What are Natural Resources?

Natural Resources are resources which are present in nature independent of human actions. 

These are the resources that are created naturally by the environment, without any help from humans. Soil, stone, sunlight, air, plants, animals, fossil fuels, etc. are all natural resources.

In simple language, natural resources are naturally occurring materials which are useful to humankind. They can also be useful in a variety of ways such as in technological, economic or social contexts. These resources include building, clothing materials, food, water, fertilisers and geothermal energy. Natural resources were traditionally within the purview of the natural sciences.

Renewable Resources: These are those resources which are endlessly available to humans for several uses. These resources are trees, wind, and water.

Non-Renewable Resources: These resources are available to humans in infinite quantities as they are not renewable and their supply may eventually run out. Minerals and fossil fuels are a few examples.

Essay on Natural Resources in 100 Words

Natural resources are parts of the natural world that are useful to humans. Renewable resources are those that can be swiftly replenished, these include soil, water, and air., Non-renewable resources are those that need time to recover, such as minerals, oil, natural gas, etc. 

One should note that the survival of all life on Earth depends on natural resources. However, the usage of natural resources in excess use can cause ecosystem disruption. Many nations are taking action these days to protect their natural resources. Natural resources shouldn’t be used for purposes outside our needs. In order to preserve non-renewable resources, we should utilise renewable resources more frequently than non-renewable ones.

Essay on Natural Resources in 150 Words

The organic aspects of nature that contribute to our way of life are known as natural resources. For survival, we rely on natural resources. Natural resources include things like air, water, soil, minerals, crops, etc. Resources like minerals, oil, and other resources are found in non-living organisms and take eons to regenerate. 

The distribution of natural resources is not even. Resources like these are also the primary driver of international trade relations for many nations. However, with time, these natural resources have now been overused by the human mankind beyond their limits. 

However, the unrestricted exploitation of natural resources is a challenge for all nations these days. To control this, a lot of nations are emphasising garbage recycling and employing more renewable resources than non-renewable ones. 

Sustainable development is the use of natural resources for current requirements without wasting them while keeping an eye on the future. It refers to the wise use of natural resources without sacrificing what coming generations will need.

Essay on Natural Resources in 200 Words

Natural resources are materials found in the environment that humans use to survive.  From the very start, humans have been dependent on these resources. While some of these resources can be restored more rapidly than others, some require more time. Resources like sunlight, water, air, and other renewable resources are readily available and have higher recovery rates than consumption rates.

On the other hand, the formation and processing of non-renewable resources, such as minerals, oil, and natural gas, take a long time. Even the usage rate of these non-renewable resources is higher as compared to the renewable resources. While some natural resources are used immediately, others must first undergo processing.

Even while renewable resources are available in huge quantities, they should also be used responsibly. Both renewable and non-renewable resources require time to be created and processed. Therefore, it is very important for humans to use these resources in a limited quantity and leave some for future generations.

With time, humans are using these resources excessively. With the ever-increasing population, humans have already created a huge impact on the environment. To begin, humans are continuously polluting the air, water and noise. Buildings are being constructed on more land. The land is becoming less valuable in this way. Humans are soon becoming the biggest reason behind depleting natural resources, such as land, water, and air. 

Therefore, we mustn’t undervalue these resources. The moment has come for us to recognise the importance of using these resources sustainably.

Natural Resources Essay

Resources are necessary for humans and other organisms to survive. The most fundamental source of all our resources is nature, and these resources are termed natural resources. If we look around, we can list many of them, like water, sunlight, flora and fauna, air etc., and we can't think of a world without these resources. Here are some sample essays on natural resources.

100 Word Essay On Natural Resources

Every living thing in the world needs resources to thrive, and nature is itself the epicentre of these resources. These gifts from nature make life on earth easy and comfortable. Centuries back, we humans were on the track of development and are still developing. We have found many hidden natural resources through this journey and used them widely. Today the population is many times more than the previous centuries, and our consumption has increased.

It is interesting to note that natural resources are divided into two, namely renewable and non-renewable. Renewable resources, for example, sunlight and wind, get renewed as they are consumed. On the other hand, non-renewable resources, for instance, coal and petroleum, take more time to replenish. So we need to use the resources wisely.

200 Word Essay On Natural Resources

No one can deny that we all depend on the resources around us. We breathe the air around us, plants use sunlight to make their supplements, and animals consume food from the forest. These all show how living organisms are so dependent on natural resources. Most natural resources are found on the earth's surface, and as civilisations grew, they explored the land and discovered resources hidden inside the planet. Since then, we have used many resources like Coal, Gold, Natural gas, uranium etc. And today, we are not using them but are rapidly exploiting them.

Types Of Resources

Some resources are abundantly found on earth, like water and air. These resources can be accessed when needed and are primarily available, called renewable resources. These resources are less likely to be depleted but can be contaminated, making them less favourable to consumption.

Another type of resource, which is available on earth in limited quantities, is termed non-renewable resources. These resources are limited and tend to exhaust over time.

Another resource category is Biotic and Abiotic resources, which means resources from living and non-living elements.

The current resource consumption rate is alarming, and if it is continuous, the world may run out of resources in the coming centuries.

500 Word Essay On Natural Resources

A natural resource is not anything complicated. Simply put, everything taken from the Earth is considered a natural resource. Sunlight, water, coal, natural gas, minerals, and even air play a role. Everything included here is regarded as a natural resource. These resources are necessary for the survival of life on earth. Energy is one of the most important products of resources and we humans extract energy from almost all of the available resources to meet our demands. Solar energy, wind energy, and hydro energy are some of them.

Types Of Natural Resources

While each natural resource has unique classifications and applications, they may be roughly divided into two groups: renewable and nonrenewable.

Renewable | Those natural resources are considered renewable if they can be readily replenished and there is an abundance of them. Sunlight, water, air, soil, biomass, and wood are all examples of such things. However, some of these resources, such as wood and mud, need more time to replenish than others.

Further, they originate from both living and nonliving sources. Renewable resources may be either organic (obtained from living organisms) or inorganic (obtained from nonliving materials).

Nonrenewable | The term "nonrenewable natural resources" refers to resources that cannot be replenished as readily as renewable ones. Not only that, but their regeneration process is prolonged and may take years. Coal, oil, gas, and other similar materials fall under this category.

Moreover, we divided everything into the organic and inorganic classes. Fossil fuel is an example of the nonrenewable organic resources that arise from the decaying remains of formerly living beings. On the other hand, non-living entities like wind, minerals, soil, and land are responsible for forming nonrenewable inorganic resources.

Distribution Of Natural Resources

There is a significant disparity in the world's natural resource distribution. In addition, several minerals and other natural resources may be abundant over the surface. Even though some places get sun, others get hardly any at all. In a similarity, certain areas are abundant in the water while others have plenty of minerals.

Climate and terrain have a pivotal role in determining resource distribution. This asymmetry is the lifeblood of international commerce, serving as the primary connection between nations. Even worse, it has unintended consequences since nations well-endowed with fossil fuels dominate the market and exploit others dependent on them for their energy needs. As a result, affluent countries are expanding their wealth while impoverished nations are sinking further into poverty.

Example Of Natural Resource

Fatu-Hiva rainforest on the Marquesas Islands is an example of an unspoiled natural resource. The forest supplies people with wood, food, water, and shelter for flora and fauna, tribes, and animals. The nutrient cycle between organisms forms food chains and promotes species diversification.

Earth is endowed with abundant natural resources. We can easily conserve them and the world if we utilise them responsibly until we transition entirely to renewable energy sources. Thus, we will use fewer nonrenewable resources. Not to mention, we cannot survive without them, making them quite crucial. In addition, we need to make good use of them and avoid wasting them in any way.

Access NCERT Solutions for Biology Chapter 14 - Natural Resources

1. How is Our Atmosphere Different from the Atmospheres on Venus and Mars?

Ans: The composition of Earth's atmosphere differs from that of Venus and Mars. The atmosphere of the Earth is composed of nitrogen, oxygen, a trace of carbon dioxide, water vapour, and other gases. This allows for the existence of life on Earth. However, carbon dioxide makes up the majority of the atmosphere on Venus and Mars, which could range between 95 to 97 per cent.

2. How Does the Atmosphere Act as a Blanket?

Ans: The atmosphere keeps the temperature of the Earth constant. It avoids a sudden increase in the temperature during the daytime due to the sun. It blocks or slows down the escape of heat from the Earth into outer space during the night- time.

3. What Causes Winds?

Ans: The uneven heating of the Earth's surface causes winds. When air is heated, it becomes lighter and rises in the atmosphere.  As a consequence, a low-pressure area is formed. The air then travels from a high-pressure area to a low-pressure area, creating wind.

4. How are Clouds Formed?

Ans: Due to the heat of the sun, a huge volume of water evaporates from various water bodies during the day and rises into the air. The air in the atmosphere heats up as a result of this. When water vapour-carrying air rises, it expands and cools. Water droplets develop as a result of the condensation of water vapour. Clouds arise as a result of the production of water droplets.

5. List Any Three Human Activities That You Think Would Lead to Air Pollution.

Ans: Three human activities that would lead to air pollution are deforestation, automobile emissions, and industrialisation all contribute to the combustion of fossil fuels.

6. Why Do Organisms Need Water?

Ans: Organisms need water as all the cellular processes need water as a medium. Also, the transportation of substances require water.

7. What is the Major Source of Fresh Water in the City/town/village Where You Live?

Ans: The major source of fresh water in the city/town/village is the River.

8. Do You Know of Any Activity Which May be Polluting This Water Source?

Ans: Discharge of wastewater from houses, industries, hospitals, etc. pollutes freshwater sources.

9. How is Soil Formed?

Ans: Various processes and factors help in the formation of the soil. The major plays by the sun, water, wind, and living organisms in soil formation.

Sun: During the day, the sun warms rocks, causing them to expand. These rocks cool and contract throughout the night. Since all parts of the rock do not expand and contract at the same rate, this causes the formation of cracks which lead to the breaking up of huge rocks into smaller pieces.

Water: Water contributes to soil formation in two ways. Water pours through the cracks in the rocks caused by the sun's heat. When this water freezes, it increases in volume. As a result, the size of the holes grows as well. The weathering of rocks is helped by this. Hard rocks are worn away over time by flowing water. Large and tiny rock fragments are frequently carried downstream by fast-moving water. These rocks scrape against one other, causing the rocks to crumble. Running water carries these smaller particles away and deposits them along its course.

Wind: Strong winds move rocks away, causing them to rub together. As a consequence, rocks are broken down into smaller and smaller bits.

Living Organisms: Some organisms, temperature rise, too, for example, Lichens, help in the development of soil. Lichens can also be found on rocks. Lichens emit specific chemicals during their development, which cause the rock surface to powder down, creating a thin coating of soil. Other tiny plants, such as moss, can now grow on this surface, causing the rock to break apart even further. The roots of large trees can occasionally become caught in cracks in the rocks, and as the roots get larger, the crack expands.

10. What is Soil Erosion?

Ans: Soil erosion is defined as when the top layer of soil is washed away from the ground surface by wind or water.

11. What are the Methods of Preventing or Reducing Soil Erosion?

Ans: Soil erosion can be avoided by afforestation, various agricultural practices that prevent topsoil removal, and grass overgrazing, among other things.

12. What are the Different States in Which Water is Found During the Water Cycle?

Ans: During the water cycle, water is found in solid-state as snow, ice, etc., in a liquid state as groundwater, river water, etc., and in a gaseous state as water vapour.

13. Name Two Biologically Important Compounds That Contain Both Oxygen and Nitrogen.

Ans: Amino acids DNA and RNA are two biologically important compounds that contain both oxygen and nitrogen.

14. List Any Three Human Activities Which Would Lead to an Increase in the Carbon Dioxide Content of the Air.

Ans: Three activities that increase the amount of carbon dioxide in the atmosphere are:

Emission from the vehicles

Burning of fossil fuels

Forest fires due to human activities, deforestation. 

What is the greenhouse effect?

Ans: A rise in the amount of methane, carbon dioxide, nitrous oxide etc. in the atmosphere would cause the average temperature to increase on a global level. This is called the greenhouse effect.

15. What are the Two Forms of Oxygen Found in the Atmosphere?

Ans: A diatomic molecular form (O2) and a triatomic molecular form (O3) of oxygen are present in the environment (O3 known as ozone).

16. Why is the Atmosphere Essential for Life?

Ans: The atmosphere maintains the Earth's average temperature fairly constant throughout the day and even throughout the year. During daytime hours, the atmosphere prevents a rapid rise in temperature. It reduces the amount of heat that escapes into space throughout the night. The atmosphere is necessary for life for all of these reasons.

17. Why is Water Essential for Life?

Ans: In a water medium, all cellular activities take place. All of the processes that occur within our bodies and cells take place between chemicals that are dissolved in water. Dissolved substances are transferred from one region of the body to another. As a result, organisms must maintain a constant amount of water within their bodies in order to survive.

18. How are Living Organisms Dependent on the Soil? Are Organisms That Live in Water Totally Independent of Soil as a Resource?

Ans: All living organisms are dependent on soil. Certain organisms rely on each other directly, while others rely on each other indirectly. Plants require soil to acquire nutrients and support. On the other hand, organisms depend on plants for food which is essential for life. Carnivores feed on animals, which in turn rely on plants for food, whereas herbivores feed on plants directly. As a result, they are indirectly dependent on soil. Water-dwelling organisms are not dependent on the soil as a source of food. Minerals are required for the survival of aquatic plants. Rivers, rains, and other natural processes transport these minerals from the soil to aquatic bodies. Aquatic life is hard to envisage without the flow of minerals from the land to the water bodies.

19. You Have Seen Weather Reports on Television and in Newspapers. How Do You Think We Can Predict the Weather?

Ans: Temperature, humidity, rainfall, wind speed, and other weather variables are collected by the meteorological department. These data are collected using various instruments. A thermometer known as a maximum-minimum thermometer is used to determine the day's maximum and lowest temperatures. The rain gauge is a device that measures the amount of rain that falls. Anemometers are used to measure wind speed. Humidity is measured using a variety of devices.

20. We Know That Many Human Activities Lead to Increasing Levels of Pollution of the Air, Water- Bodies and Soil. Do You Think That Isolating These Activities to Specific and Limited Areas Would Help in Reducing Pollution?

Ans: Yes, limiting human activity to restricted regions will undoubtedly aid in pollution reduction. For instance, Industries that are set up in the isolated regions will not contaminate the water resource, fertile land and agricultural land. To some extent, these methods will reduce pollution.

21. Write a Note on How Forests Influence the Quality of Our Air, Soil and Water Resources.

Ans: Forests have a variety of effects on all-natural resources. The below are a few examples. They keep the quantity of $$CO_2$$ and oxygen in the atmosphere in check. Forests help to minimize soil erosion by retaining the fertile soil in place with their roots. Forests contribute to the recovery of water supplies. Plants lose water through transpiration, which then condenses to produce clouds. These clouds produce rain, which replenishes water bodies.

NCERT Class 9 Science Chapter 14 Solutions- Natural Resources

Introduction.

Earth is the only planet where life is found. This life exists because of its resources which include the land, water and air. There are several other resources on which life forms are reliable. Alongside, it also comprises the biotic and abiotic components of life. 

14.1 The Breath of Life: Air

The atmosphere is a composition of several gases which include nitrogen, carbon, oxygen, water vapours, etc. Atmosphere covers the earth like a blanket keeping the temperature steady. It also plays a key role in reducing the amount of heat escaping into outer space. 

Air Pollution

It is caused because of the harmful and toxic elements present in the atmosphere, some of which include pollutants and organic molecules. The causes of air pollution are mostly because of human-made sources which include fuel combustion, smoke, etc. The other natural causes include forest fires, etc. The air pollution has several negative effects on the atmosphere, which include global warming, acid rain, respiratory diseases, etc. 

14.2 Water: A Wonder Liquid

Under this section, we talk of water which is among the most important resources. Only 3% of water available on earth is freshwater, the remaining 97% of which is covered by oceans. 

Water Pollution

It happens when water is contaminated due to excessive pollutants being discharged in the water bodies without adequate treatment. Some of the causes of water pollution include:

Agriculture

Urbanisation

Transpiration

It is the process in which the water is lost in the atmosphere from parts of a plant called stomata. 

Evaporation

It is the process through which water is lost in the atmosphere in the form of vapours. 

14.3 Mineral Riches in The Soil

This section talks about soil, its importance and its components. It is the uppermost layer of the earth’s crust. Soil is formed due to continuous weathering of the mountains. The factors which lead to soil formation include:

Parent material

Organisms present in the soil

Composition of Soil

Soil is made of organic matter, the basic components of which include water, air, and other inorganic matter as well. There are various types of soils across different regions. 

Soil Pollution

Soil pollution is defined as the addition of harmful substances to the soil, which makes it unproductive. Some of the pollutants include acid rain, industrial wastes, etc. 

Soil Erosion

It is yet another form of soil degradation. The prime agents which lead to soil erosion include rainwater, wind, flowing water, etc. Soil erosion leads to a loss of topsoil, which further reduces the potential for crop production. 

14.4 Biogeochemical Cycles

These are defined as the biological cycles in which natural elements are circulated through both biotic and abiotic parts in the ecosystem. 

There are Mainly Three Biogeochemical Cycles Which Include:

Carbon cycle

Nitrogen cycle

Oxygen cycle

14.5 Ozone Layer

It is defined as a thin layer which acts as a shield for the earth, protecting it from the injurious radiation of the sun. It mainly consists of high concentrations of ozone. 

FAQs on NCERT Solutions for Class 9 Science Chapter 14 - Natural Resources

• Solved Questions on Natural Resources

Natural resources are the materials and components that occur naturally in the environment and are utilised by humans for various purposes. These resources are essential for sustaining life, supporting economic activities, and maintaining ecosystems. Natural resources can be broadly categorised into two main types: renewable and non-renewable resources.

1. Inexhaustible Natural Resources

These resources are abundant and not likely to be depleted despite continuous use.

Examples include:

• Air: The Earth's atmosphere, composed mainly of gases like nitrogen, oxygen, and carbon dioxide, is an inexhaustible resource.
• Water: Oceans, rivers, lakes, and groundwater provide a constant supply of water.
• Solar Energy: The sun's energy is an ongoing source of power that can be harnessed using solar panels.

2. Exhaustible Natural Resources

These resources are available in limited quantities and can be depleted with continuous and unchecked use. Exhaustible resources are further divided into two categories:

a) Renewable Resources:  These resources can replenish themselves naturally over time, given responsible use.

• Forests: Trees can regrow and renew themselves through reproduction, making them a renewable resource.
• Wildlife: Populations of various animal species can reproduce and sustain themselves if conservation efforts are in place.
• Soil: Proper soil management practices can allow soil to regenerate and remain fertile.
• Underground Water: Responsible water usage and management can ensure a sustainable supply of underground water.

b) Non-renewable Resources: These resources cannot naturally replenish themselves in human timescales. Once they are depleted, they are gone.

• Minerals: Elements like iron, copper, and aluminium are finite in supply and cannot be regenerated within human lifetimes.
• Fossil Fuels: Coal, oil, and natural gas are formed over millions of years and cannot be renewed in a short time. Once extracted and used, they are gone.

Air is a mixture of gases that surrounds the Earth. It is composed of various gases, with nitrogen and oxygen being the most abundant. Other gases, such as carbon dioxide, argon, and trace amounts of other gases, also contribute to the composition of air. Air is essential for sustaining life on Earth and plays a crucial role in many natural processes.

The atmosphere is the layer of gases that surrounds the Earth and is held in place by gravity. It is divided into different layers based on altitude, each with distinct characteristics. The main layers, from lowest to highest, are the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The atmosphere serves several important functions:

• Protection: The atmosphere acts as a protective shield, absorbing and scattering harmful solar radiation (UV rays) and cosmic rays. It prevents these radiations from reaching the Earth's surface and causing damage to living organisms.
• Climate Regulation: The atmosphere plays a vital role in regulating the Earth's temperature. Greenhouse gases, such as carbon dioxide and water vapour, trap heat and maintain the planet's temperature within a habitable range. This phenomenon is known as the greenhouse effect.
• Weather Patterns: The movement of air masses and the distribution of heat contribute to the formation of weather patterns. The atmosphere carries moisture, which condenses to form clouds and precipitation. Wind patterns are influenced by differences in temperature and pressure.
• Oxygen Supply: Oxygen, present in the atmosphere, is essential for the respiration of humans, animals, and most organisms. It supports cellular processes and energy production.
• Carbon Cycle: The atmosphere is involved in the carbon cycle, where carbon dioxide is exchanged between the atmosphere, oceans, and land through processes like photosynthesis and respiration.

Wind: Causes and Patterns

Air movement, known as wind, is a fundamental aspect of our atmosphere, influencing our daily experiences and weather patterns. The intricate dance of wind is driven by various factors, including temperature differentials, pressure variations, and Earth's rotation.

• Causes of Air Movement: The primary driver of air movement is the uneven heating of the Earth's surface by solar radiation. This process creates variations in temperature and pressure, prompting air to flow from areas of high pressure to those of low pressure. These movements give rise to the diverse wind patterns we observe.
• Temperature and Pressure Gradients: The intensity and character of wind, whether a gentle breeze or a powerful storm, depend on the degree of temperature and pressure differences between regions. Regions receiving more sunlight become warmer, leading to the expansion of air and lower pressure. Conversely, cooler regions experience denser air and higher pressure. This contrast in pressure propels the air, creating wind currents.
• Diurnal Air Movement: Coastal areas exhibit distinct air movement patterns due to the uneven heating of land and water. During the day, land heats up more quickly than water, causing cooler air from the sea to flow toward the warmer land. It is known as the sea breeze. At night, the land cools rapidly, leading to a reversal in air flow as cooler air from the land moves toward the warmer sea. This is known as a land breeze. These shifts are driven by the variations in heating rates between land and water.

• Vertical Air Movement and Fronts: The interplay of temperature and pressure gradients also leads to vertical air movement. Warmer air near the surface, being lighter, rises, creating a low-pressure area. This uplift can lead to cloud formation and precipitation. Additionally, the collision of warm and cold air masses generates fronts and depressions, contributing to the complexity of Earth's atmospheric dynamics.

• The Coriolis Effect: The Coriolis Effect is a phenomenon that occurs due to the Earth's rotation. When objects, like air or water, move across the Earth's surface, they appear to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection happens because the Earth is rotating beneath these moving objects.

Imagine you're standing on a spinning carousel, and you throw a ball to someone across from you. To you, the ball appears to curve as it travels, even though you threw it in a straight line. This is similar to how the Coriolis Effect works. The Earth is like that spinning carousel, and anything that moves across its surface, like air masses or ocean currents, seems to curve due to the Earth's rotation.

The Coriolis Effect has a significant impact on various phenomena, especially large-scale movements like global wind patterns and ocean currents. It influences the way weather systems, like hurricanes, rotate and move. This effect is essential for understanding Earth's dynamic systems and how they interact with its rotation.

Air pollution refers to the presence of harmful substances in the air that can have adverse effects on human health, the environment, and ecosystems. These pollutants can originate from natural sources, such as volcanic eruptions and wildfires, or human activities, such as industrial processes, transportation, and burning of fossil fuels.

Common Air pollutants

• Particulate matter (PM): Tiny solid particles or liquid droplets suspended in the air.
• Ground-level ozone (O 3 ): A component of smog formed by the reaction of pollutants in the presence of sunlight.
• Nitrogen oxides (NOx): Gases produced from combustion processes, contributing to smog and acid rain.
• Sulphur dioxide (SO 2 ): A gas produced from burning fossil fuels and industrial processes, leading to acid rain.
• Volatile organic compounds (VOCs): Gases emitted from vehicles, industrial processes, and solvents.
• Carbon monoxide (CO): A colourless, odourless gas produced by incomplete combustion.

Effects of Air Pollution

Air pollution can have a range of negative effects on human health, the environment, and the atmosphere:

• Health Impacts: Air pollutants can cause respiratory and cardiovascular diseases, aggravate asthma, and lead to premature death. Long-term exposure to polluted air is linked to chronic health conditions.
• Environmental Impact: Air pollution can harm plant life, damage crops, and acidify soils. It can also affect aquatic ecosystems by contaminating water bodies through deposition.
• Smog Formation: High levels of air pollutants can lead to the formation of smog, a type of air pollution characterised by a hazy appearance and poor visibility.
• Global Warming: Some air pollutants, such as carbon dioxide and methane, contribute to global warming by enhancing the greenhouse effect and causing temperature rise.
• Ozone Depletion: Certain pollutants can lead to the depletion of the ozone layer, allowing harmful UV radiation to reach the Earth's surface, increasing the risk of skin cancer and other health issues.
• Acid Rain: Pollutants like sulphur dioxide and nitrogen oxides can combine with water vapour in the atmosphere to form acid rain. Acid rain damages vegetation, aquatic ecosystems, and buildings.

Water is a colourless, odourless, and tasteless substance that covers about 71% of Earth's surface. It exists in various forms – solid (ice), liquid (water), and gas (water vapour) – and plays a fundamental role in supporting life on our planet. Water is a universal solvent, meaning it can dissolve a wide variety of substances, making it essential for many biochemical processes. It is also a major component of all living organisms.

Hydrosphere

The hydrosphere refers to the total amount of water on Earth's surface, including oceans, rivers, lakes, glaciers, groundwater, and even water vapour in the atmosphere. It's a dynamic system where water constantly moves and cycles through different forms and locations.

Water Pollution

Water pollution refers to the contamination of water bodies – including rivers, lakes, oceans, and groundwater – by harmful substances. Pollutants can originate from various sources and have detrimental effects on aquatic ecosystems, human health, and the environment.

Sources of Water Pollution

a) Point Sources of Water Pollution: Point sources are pollution discharge points that have a specific and identifiable location from which pollutants are directly released into water bodies. These sources are usually well-defined and relatively easier to monitor and regulate. Because point sources have a fixed location, it is often possible to implement pollution control measures, such as installing treatment systems, before the pollutants are discharged into water bodies. Regulations and permits can be issued to ensure that the released pollutants meet acceptable standards.

Some examples of point sources include:

• Factories and industrial facilities that release wastewater containing chemicals, heavy metals, and other pollutants.
• Power plants that discharge heated water into water bodies.
• Sewage treatment plants that release treated or untreated wastewater.
• Underground coal mines and oil wells may release pollutants into groundwater.

b) Non-point Sources of Water Pollution: Non-point sources are diffuse and scattered pollution inputs that do not have a specific discharge point. They result from the runoff of pollutants from various land surfaces, making them more challenging to identify and control.

Some examples of non-point sources include:

• Runoff from agricultural fields carrying fertilisers, pesticides, and soil particles.
• Urban runoff from roads, streets, and parking lots carrying oil, chemicals, and litter.
• Runoff from lawns and gardens containing fertilisers and pesticides.
• Erosion from construction sites, logging areas, and disturbed land.

Causes of Water Pollution

• Industrial Discharges: Factories and industries release various chemicals, heavy metals, and pollutants into water bodies through their wastewater.
• Agricultural Runoff: Excessive use of fertilisers, pesticides, and herbicides in agriculture can lead to runoff that carries these chemicals into water bodies.
• Sewage and Wastewater: Improperly treated or untreated sewage and wastewater release harmful pathogens and pollutants into water bodies.
• Oil Spills: Accidental or intentional release of oil into water bodies can harm aquatic life and degrade water quality.
• Plastic and Trash: Improper disposal of plastic waste and other debris can accumulate in water bodies, harming marine life and ecosystems.
• Mining Activities: Mining operations can release heavy metals and toxic substances into nearby water bodies.

Effects of Water Pollution

• Impact on Human Health: Contaminated water sources can lead to various waterborne diseases, including cholera, typhoid, dysentery, hepatitis, and gastrointestinal infections. Pathogens like bacteria, viruses, and parasites present in polluted water can cause severe illnesses and even death, particularly in areas with inadequate sanitation and water treatment facilities.
• Aquatic Ecosystem Damage: Pollutants can disrupt aquatic ecosystems, killing aquatic organisms, disrupting food chains, and reducing biodiversity.
• Loss of Biodiversity: Water pollution can harm aquatic plants and animals, leading to habitat destruction and a loss of biodiversity. Many species of fish, amphibians, and invertebrates are sensitive to changes in water quality and can be severely impacted by pollution. This can disrupt entire food chains and ecological relationships.
• Depletion of Oxygen: Organic pollutants from sewage and industrial waste can lead to increased microbial activity during decomposition. As microorganisms break down these pollutants, they consume oxygen from the water, leading to reduced oxygen levels. Low oxygen levels (hypoxia) can cause "dead zones" where aquatic life cannot survive.
• Economic Impact: Industries that rely on clean water, like fishing and tourism, can suffer economic losses due to polluted water bodies.
• Food Chain Contamination: Pollutants can accumulate in the food chain, affecting both aquatic and human organisms that rely on contaminated sources.
• Eutrophication: Eutrophication is a process that occurs when water bodies, such as lakes, rivers, and ponds, become enriched with excess nutrients, particularly nitrogen and phosphorus. These nutrients often come from sources like agricultural runoff, sewage discharge, and industrial effluents. The excessive nutrients cause rapid growth of algae and aquatic plants, leading to a series of detrimental effects.

Preventing Water Pollution

Efforts to prevent water pollution include:

• Regulations: Governments enact laws and regulations to limit pollutant discharges and protect water quality.
• Wastewater Treatment: Industries and municipalities treat their wastewater before releasing it into water bodies.
• Waste Management: Proper disposal and recycling of waste, especially plastics, can prevent pollutants from entering water bodies.
• Conservation Practices: Implementing sustainable agriculture practices, reducing fertiliser use, and promoting responsible waste disposal can help prevent pollution.
• Public Awareness: Educating individuals about the importance of clean water and responsible behaviour can lead to more conscious water use and pollution prevention.

Rainwater harvesting is a technique used to collect and store rainwater for various purposes. It involves the capture of rainwater from surfaces like rooftops, which is then stored in tanks or underground reservoirs. Rainwater harvesting can provide a sustainable source of fresh water in areas with low rainfall or limited access to surface or groundwater. It has several benefits:

• Water Conservation: Harvesting rainwater reduces the demand for other water sources, easing pressure on freshwater supplies.
• Reduced Flooding: Collecting rainwater reduces surface runoff, which can help mitigate flooding during heavy rainfall.
• Groundwater Recharge: By infiltrating into the ground, harvested rainwater can replenish underground aquifers and maintain groundwater levels.
• Cost Savings: Rainwater harvesting can reduce the cost of water bills, especially for non-potable uses like irrigation and toilet flushing.

Soil is a complex mixture of minerals, organic matter, water, air, and living organisms that covers the Earth's land surface. It plays a crucial role in supporting plant growth, providing nutrients to organisms, filtering and storing water, and serving as a habitat for various organisms. Soil is formed through the process of weathering of rocks and the accumulation of organic material over time.

Formation of Soil

Soil formation is a gradual process influenced by various factors, including climate, parent material (rock from which soil forms), topography, organisms, and time. The process involves physical, chemical, and biological interactions:

• Weathering: Weathering is the initial step where rocks are broken down into smaller particles. Physical weathering involves processes like freezing and thawing that break rocks apart. Chemical weathering involves reactions with water, gases, and minerals, leading to rock decomposition.
• Organic Matter Accumulation: As plants and animals decay, they contribute organic matter to the soil. This organic matter enriches the soil's fertility by providing nutrients and creating a better environment for organisms.
• Leaching: Water moving through the soil can carry dissolved minerals and nutrients from the upper layers down to the lower layers. Leaching plays a crucial role in redistributing nutrients within the soil profile.
• Mineralization: Organic matter present in the soil decomposes over time through microbial activity. This decomposition releases nutrients, such as nitrogen, phosphorus, and potassium, into the soil.
• Humus Formation: Partially decomposed organic matter accumulates as dark, nutrient-rich humus. Humus enhances soil structure, water-holding capacity, and nutrient retention.
• Soil Horizons: Over time, distinct layers or horizons form within the soil profile. Each horizon has its own unique characteristics, including texture, colour, and nutrient content. The different horizons are labelled as O, A, B, C, and sometimes even deeper layers.

Composition of Soil

Soil is a complex mixture of various components, each contributing to its overall characteristics and properties. The composition of soil includes:

• Mineral Particles: Soil is primarily composed of mineral particles, which are categorised based on their size: sand, silt, and clay. Sand particles are the largest, followed by silt particles, and clay particles are the smallest. The relative proportions of these particles determine the soil's texture. Sandy soils have larger particles, allowing for good drainage but lower water-holding capacity. Clay soils have small particles, leading to higher water retention but poor drainage. Silt falls between these two extremes.
• Organic Matter: Organic matter in the soil consists of decomposed plant and animal materials. It plays a crucial role in soil fertility, structure, and nutrient availability. Organic matter improves soil's water-holding capacity, aeration, and nutrient-holding capacity. It also provides a habitat for beneficial soil organisms.
• Water: Water is present in the spaces between soil particles. It is essential for plant growth and nutrient transportation within the soil. The amount of water soil can hold depends on its texture and structure.
• Air: Air also occupies the spaces between soil particles. Adequate air circulation in the soil is crucial for root respiration and the survival of soil organisms.

The relative proportions of these components influence soil properties such as drainage, water-holding capacity, aeration, fertility, and suitability for plant growth.

Types of Soil

Soils are categorised based on their particle size and properties:

• Clay Soil: This type of soil has fine particles and retains water well. It can become easily compacted, leading to drainage issues and poor aeration.
• Sandy Soil: Sandy soil has larger particles and doesn't retain water well. It provides good drainage and aeration but may lack essential nutrients.
• Silt Soil: Silt soil contains fine particles that are smaller than sand but larger than clay. It has good water retention and drainage properties and is fertile.
• Loam Soil: Loam soil is a balanced mixture of sand, silt, and clay. It has good water-holding capacity, and proper drainage, and is considered ideal for plant growth.
• Peat Soil: Peat soil is rich in organic matter and retains a lot of moisture. It's often found in wetlands and can be fertile but requires careful management.

Effect of Minerals on Soil Fertility

• Limestone: Limestone is calcium carbonate and can neutralise acidic soils, raising pH. It enhances fertility by improving nutrient availability in slightly acidic soils.
• Phosphate Minerals: Minerals like apatite provide phosphorus, a crucial nutrient for plant growth. Adding phosphate-rich minerals or fertilisers enhances soil fertility.
• Potassium Minerals: Minerals like feldspar release potassium as the weather. Potassium is essential for root development and overall plant health.
• Organic Matter: Adding materials like compost, manure, and plant residues improves soil structure, water retention, and nutrient availability, thus boosting fertility.
• Micronutrient-Bearing Minerals: Minerals containing micronutrients like iron, zinc, and copper contribute to soil fertility by providing essential trace elements for plants.

Soil erosion is the process of detachment and movement of soil particles from their original location by agents like water, wind, and human activities.

Causes of Soil Erosion

• Water Erosion: This type of erosion occurs due to the impact of rainfall, surface runoff, and water currents. Raindrops dislodge soil particles, which can be transported by flowing water. Streams, rivers, and even ocean currents can carry away eroded soil. Water erosion is particularly prominent on sloped landscapes.
• Wind Erosion: Wind erosion is common in arid and semi-arid regions with sparse vegetation cover. Strong winds lift and carry loose soil particles, causing them to collide with other surfaces or drop in different areas. This process is most likely to happen when the soil is dry and lacks vegetation to anchor it.
• Human Activities: Human-induced factors can greatly accelerate soil erosion:
• Deforestation: Removing trees and plants exposes soil to the impact of raindrops and reduces root systems that help hold soil in place.
• Construction: Grading and construction activities disturb the soil's natural structure and increase its vulnerability to erosion.
• Overgrazing: Continuous grazing by livestock removes vegetation cover, leaving the soil exposed to erosive forces.

Improper Agricultural Practices: Practices like ploughing along slopes, leaving fields bare between crops, and not implementing proper soil conservation measures can lead to soil erosion.

Effects of Soil Erosion

Soil erosion can have significant and far-reaching impacts on both the environment and human activities. Some of the key effects of soil erosion include:

• Loss of Fertility: Eroded topsoil contains valuable nutrients and organic matter essential for plant growth. As this nutrient-rich layer is carried away, the remaining soil becomes less fertile, leading to decreased agricultural productivity.
• Reduced Agricultural Productivity: The loss of fertile topsoil directly affects crop yields and agricultural productivity. Farmers may experience lower harvests and struggle to grow healthy crops.
• Sedimentation: Eroded soil particles can be transported by water runoff into rivers, lakes, and other water bodies. This sedimentation not only reduces the water-holding capacity of these bodies but also degrades water quality by carrying pollutants and nutrients. Aquatic habitats and ecosystems can suffer as a result.
• Landslide Risk: Soil erosion weakens the stability of slopes and hillsides. As the protective topsoil layer is eroded, the underlying soil becomes more prone to landslides, especially during heavy rainfall or other erosive events. Landslides can damage infrastructure, disrupt communities, and pose safety risks.
• Impact on Infrastructure: Eroded soil can accumulate in areas such as roads, ditches, and drainage systems, causing blockages and reducing the efficiency of these structures. This can lead to increased maintenance costs and disruptions to transportation.
• Desertification: In severe cases, continuous soil erosion can lead to the expansion of desert-like conditions, where fertile land turns into unproductive arid landscapes. This process, known as desertification, has serious consequences for local communities and ecosystems.
• Economic Consequences: The negative effects of soil erosion can result in economic losses for agricultural sectors, increased expenses for sediment cleanup in water bodies, and the need for soil conservation efforts. These economic impacts can ripple through communities and regions.

Prevention of Soil Erosion

Implementing effective soil erosion prevention measures is crucial for maintaining soil health and sustainability. Some key strategies for preventing soil erosion include:

• Plant Vegetative Cover: Planting and maintaining vegetation, such as grasses, shrubs, and trees, provides natural protection against soil erosion. The vegetation acts as a barrier, reducing the impact of raindrops and wind on the soil surface, and preventing detachment and erosion.
• Terracing: Constructing terraces on slopes involves creating level platforms with short vertical slopes. Terracing slows down the flow of water down the slope, allowing more time for water to infiltrate the soil. This helps to reduce erosion and retain moisture.
• Contour Farming: Ploughing and planting crops perpendicular to the slope contour rather than following the slope helps to slow down water runoff. This method reduces the speed at which water flows across the land, minimising erosion and allowing water to infiltrate the soil more effectively.
• Cover Crops: Planting cover crops, also known as green manure, between main crops, helps protect the soil from erosion during periods when the main crops are not growing. Cover crops improve soil structure, reduce surface runoff, and prevent soil from being exposed to erosive forces.
• Mulching: Applying a layer of organic or synthetic materials, such as straw, wood chips, or plastic, to the soil surface helps to reduce erosion by creating a protective barrier. Mulch slows down water flow, prevents soil splashing, and promotes water infiltration.
• Windbreaks: Planting rows of trees or shrubs along the edges of fields helps reduce wind erosion by acting as a wind barrier. Windbreaks also provide habitat for wildlife and can have multiple benefits beyond erosion prevention.
• Erosion-Control Structures: Installing physical structures like silt fences, check dams, and sediment ponds in areas prone to erosion can capture sediment and prevent it from entering water bodies.
• Sustainable Land Management: Adopting integrated land management practices that take into account soil health, water management, and crop selection can contribute to long-term erosion prevention.

Soil pollution refers to the contamination of soil with pollutants such as chemicals, heavy metals, pesticides, industrial waste, and sewage.

Causes of Soil Pollution

Soil pollution occurs due to various human activities that introduce harmful substances into the soil, affecting its quality and fertility. Some key causes of soil pollution include:

• Industrial Activities: Industries release pollutants and hazardous chemicals into the environment. These pollutants can find their way into the soil through various pathways, contaminating it with heavy metals, toxins, and synthetic chemicals.
• Agricultural Chemicals: The excessive use of pesticides, herbicides, and synthetic fertilisers in agriculture can lead to the accumulation of toxic chemicals in the soil. These chemicals can disrupt soil ecosystems and impact both soil and water quality.
• Improper Waste Disposal: The improper disposal of various types of waste, including untreated sewage, household waste, and electronic waste, can contaminate the soil. Toxic substances from these wastes can leach into the soil, posing risks to human health and the environment.
• Mining Activities: Mining operations can release heavy metals, toxic chemicals, and acidic substances into the soil. These contaminants can persist in the soil for long periods, affecting soil structure and fertility.
• Urbanization: The expansion of urban areas brings increased construction activities, vehicle emissions, and waste generation. Urban waste disposal, improper management of construction materials, and vehicle-related pollutants can all contribute to soil pollution.
• Deforestation: Clearing forests for agriculture or development exposes the soil to erosion and degradation. Soil in deforested areas is more vulnerable to pollution from other sources due to reduced vegetation cover.
• Contaminated Water Irrigation: Using contaminated water for irrigation can introduce pollutants and toxins into the soil. Irrigation with untreated or polluted water can lead to the accumulation of salts, heavy metals, and pathogens in the soil.
• Atmospheric Deposition: Airborne pollutants, such as heavy metals, can be deposited onto the soil through rain, dust, and industrial emissions. These pollutants can accumulate in the soil over time.
• Chemical Spills and Accidents: Accidental spills of chemicals, oil, or hazardous substances can lead to immediate soil contamination. These spills can impact the soil's physical, chemical, and biological properties.
• Landfill Leachate: Leachate from landfills contains a mixture of pollutants that can seep into the surrounding soil, contaminating it with a range of hazardous substances.

Effects of Soil Pollution

Soil pollution has far-reaching consequences for the environment, human health, and ecosystems. Some of the key effects of soil pollution include:

• Reduced Soil Fertility: Pollutants in the soil can disrupt the natural nutrient balance, making essential nutrients less available to plants. This results in reduced crop yields and overall plant growth, impacting agricultural productivity.
• Contaminated Food Chain: Pollutants present in the soil can be taken up by plants and subsequently transferred to animals and humans through the food chain. This can lead to the accumulation of harmful substances in edible parts of plants and animals, posing risks to human health.
• Groundwater Contamination: Pollutants from the soil can leach into groundwater, which is a vital source of drinking water for many communities. Contaminated groundwater can carry toxic substances, heavy metals, and chemicals, affecting drinking water quality and endangering public health.
• Negative Impact on Biodiversity: Soil pollution can harm soil-dwelling organisms such as earthworms, bacteria, fungi, and other microorganisms that play crucial roles in nutrient cycling and maintaining soil structure. The disruption of soil ecosystems can have cascading effects on higher trophic levels, impacting biodiversity.
• Ecosystem Disruption: Polluted soil can disrupt entire ecosystems by affecting the health and vitality of plants, animals, and microorganisms. Soil pollution can alter the composition of plant communities, leading to changes in animal populations and overall ecosystem dynamics.
• Soil Structure Degradation: Pollutants can alter the physical properties of soil, causing compaction, reduced water-holding capacity, and decreased soil porosity. These changes can negatively impact plant root growth and water infiltration.
• Air Quality Impacts: Some pollutants in contaminated soil can become airborne through processes like volatilization or wind erosion. These airborne pollutants can contribute to poor air quality and may have additional negative impacts on human health.
• Health Risks to Humans: Direct exposure to polluted soil can lead to various health risks for humans, such as skin diseases, respiratory issues, and the absorption of toxic substances. Consuming crops grown in polluted soil can also pose health hazards.
• Economic Losses: Soil pollution can lead to economic losses in agriculture due to reduced crop yields, increased input costs, and the need for soil remediation measures. It can also impact tourism and property values in contaminated areas.

Prevention and Mitigation of Soil Pollution

• Proper Waste Management: Effective disposal and treatment of industrial, household, and electronic waste prevent harmful substances from leaching into the soil. Safe waste disposal facilities, recycling, and proper hazardous waste management minimise the introduction of pollutants into the environment.
• Integrated Pest Management: By reducing reliance on chemical pesticides and incorporating practices like crop rotation, biological control, and using pest-resistant crop varieties, agricultural pollution from excessive pesticide use can be minimised.
• Soil Testing: Regular soil testing allows farmers, landowners, and authorities to monitor soil quality, identify potential contamination, and take corrective measures to maintain healthy soil conditions.
• Bioremediation: This technique utilises the natural abilities of certain plants and microorganisms to break down or remove pollutants from the soil. Plants may absorb and accumulate contaminants, while microorganisms can break down pollutants through biological processes.
• Reforestation: Planting trees and restoring vegetation cover helps prevent soil erosion by stabilising the soil with their root systems. Trees also play a role in absorbing pollutants and promoting healthy soil microbial communities.
• Regulation and Legislation: Enforcing strict environmental regulations and policies establishes guidelines for industries, agriculture, and individuals to follow responsible practices and reduce pollution.
• Contaminated Site Remediation: In cases where soil pollution has already occurred, various techniques such as soil excavation, soil washing, and soil vapour extraction can be employed to remove or treat contaminants and restore soil quality.
• Public Awareness and Education: Educating communities about the importance of responsible soil management practices, waste reduction, and pollution prevention raises awareness and encourages collective efforts to safeguard soil health.
• Green Infrastructure: Designing urban spaces with green roofs, permeable pavements, and vegetation helps manage stormwater runoff, prevent soil erosion, and mitigate pollution by providing natural filtration.
• Industrial Best Practices: Industries can adopt cleaner production methods, reduce emissions, and implement proper waste disposal systems to minimise the release of pollutants into the environment.
• Wastewater Treatment: Treating industrial and domestic wastewater before it is discharged into the environment prevents harmful chemicals and contaminants from infiltrating the soil and groundwater.

Long and Short Essay on Natural Resources in English

Natural resources essay – 1 (200 words).

Natural resources are the resources that are available naturally on our planet. We do not require any human intervention to derive them. These resources are essential for the survival of living beings. While some of the natural resources such as air, water and sunlight are used directly; others serve as raw material to produce various items of necessity.

Many of the natural resources are present in abundance and are renewable. This means that these can be recycled and reused. However, there are many others that are non-renewable or take thousands of years to replenish. Many natural resources are depleting fast. This is owing to several reasons. One of the main reasons is the growth in population. The consumption of natural resources is on an increase continually owing to the rapid population growth.

Deforestation is another cause for the depletion of natural resources. Land is being used for urbanization. This has led to the loss of wildlife and trees. The raw material derived from them is thus decreasing by the day. The growing pollution is affecting the water bodies negatively. The coming generations may have to face scarcity of water that was once available in abundance.

It is high time we humans must stop wasting the natural resources and use them wisely.

Natural Resources Essay – 2 (300 words)

Introduction

Natural resources are the resources that are made available by nature. Man does not have to work to derive these resources. Some of the examples of natural resources include water, air, sunlight, wood, minerals and natural gases. While many of the natural resources are available abundantly in nature others take time to form and are not available as freely.

Types of Natural Resources

While the characteristics and use of each natural resource is different from the other, these have broadly been classified in two categories. These are the renewable natural resources and non-renewable natural resources. Here is a look at these in detail:

• Renewable Natural Resources : Renewable natural resources, as the name suggests are the ones that can be renewed naturally and used over and over again. Water, solar energy, wood, biomass, air and soil fall under this category. While many of these resources such as water, air and sunlight is easily renewable it takes time to renew natural resources such as wood and soil. Renewable resources are further categorized into organic and non-organic.

When renewable resources are derived from living things like animals and plants these are termed as organic renewable resources. When renewable resources are derived from non-living things, they are termed as inorganic renewable resources.

• Non-Renewable Natural Resources : These are the resources that cannot be renewed or recycled or take a very long time to form again. Coal, oil, minerals and natural gases are examples of non renewable natural resources. While these form naturally without any human intervention, non-renewable natural resources such as minerals may take thousands of years to form. These are also divided into two categories – Organic and Non-organic.

Non-renewable natural resources derived from living organisms are called organic natural resources. One of the examples of this can be fossil fuel.

Non-renewable natural resources derived from non-living things such as wind, minerals, land and soil are known as inorganic natural resources.

Natural resources, especially the non-renewable resources, must be used wisely so that these are not depleted from nature.

Natural Resources Essay – 3 (400 words)

Natural Resources are the resources that have been available in nature since the beginning of the time. These resources make life possible on earth. Life on our planet would not have been possible without natural resources such as air, sunlight and water. Other natural resources are also as important and have become an integral part of our life.

Natural Resources Employed to Different Uses

While natural resources fulfil the basic necessities of man and other living beings on earth, they also form the basis for deriving various things. These things make life easier and comfortable. Today, man cannot imagine his life without most of these. Here is a look at the various ways in which natural resources are used:

• Sunlight : It is used to generate solar power which is used in various appliances. Sunlight also enables the process of photosynthesis.
• Air : Air is used to generate wind energy. Wind mills are employed to generate the same. It is used for various purposes such as grinding grains and pumping water.
• Water : Water is used to generate hydroelectric energy. It is also used for various cleaning tasks and cooking.
• Minerals : Minerals are used for generating several items that are used in our day to day lives. Wires, aluminium cans and parts of automobiles are among some of the things that are made with different kinds of minerals. Minerals such as gold and silver are used to craft jewellery.
• Natural gases : These are used to generate electricity. These are also used in the kitchen for the purpose of heating.
• Coal : This is another natural resource which is used for the purpose of generating electricity.
• Plants : Plants offer a number of natural resources such as wood, fruits and vegetables. While fruits and vegetables are essential to keep the living beings alive, wood is used to manufacture various pieces of furniture, paper and other products.
• Animals : Animals also provide numerous natural resources. They provide milk which is used to produce curd, cheese, butter and many other dairy products. Animal fur and skin are also used to derive various clothing items and other things of necessity. Woollen sweaters and caps, leather belts and bags, silk saris and bed linens are among some of the things made with the natural resources derived from animals.

Thus, natural resources are not only useful in their raw form but are also useful when they are employed to generate other stuff. Man has certainly made use of these resources in the best possible ways to make life better.

Natural resources are a gift of the nature. These are consumed by the living organisms directly as well as indirectly. Direct consumption of natural resources implies using these resources in their pure form. The best examples of these can be sunlight and oxygen. Indirect consumption of natural resources means using them by modifying them or by generating other goods and services with their help. For instance, minerals, wood and many other natural resources are crafted into different materials before putting them to use.

Uses of Different Natural Resources

Natural Resources offer several uses. Without these, life would not be possible on earth. As per a survey, the developed countries use greater amount of natural resources compared to under-developed countries. Here is how these are used for various purposes:

Natural resources produced by animals are the kind of natural resources that are much in demand. This is because they provide us food which is essential for the survival of the living beings. Animals are tamed and reared to fetch organic natural resources from them. Milk and other dairy products that provide essential nutrients to the living beings are derived from animals. Fossil fuels derived from animal wastes are also employed for various tasks such as heating, running vehicles and generating electricity. Animal fur and skin is used for manufacturing clothes, bags, shoes, belts and other such items.

Plants provide us with fruits and vegetables that are essential for the survival of the living beings. Various medicines for curing different illnesses are also produced from these natural resources. Plants also provide us oxygen and absorb the harmful and toxic gases such as carbon dioxide and carbon monoxide. This functions naturally without any human interaction. Besides, plant waste also contributes in producing fossil fuels which are used in various ways.

Apart from this, trees provide wood that is used for various purposes such as constructing houses, crafting furniture, making paper and producing various other big and small things that we cannot do without.

• Minerals and Metals

Metals and minerals are also used for different purposes. All of these have their unique properties and are useful in their own way. Some of the uses of minerals and metals include creating batteries, manufacturing medical equipments, manufacturing automobile parts, crafting jewellery, constructing buildings and manufacturing utensils. These resources are limited and fall under the non-renewable natural resources category.

• Sunlight, Air and Water

The importance and use of these natural resources is known to all. These are available in abundance in the atmosphere and are used directly in their pure unadulterated form by the living beings. These are also modified and used to run various processes. Fortunately, these are renewable natural resources and are replenished and replaced easily.

We consume a good amount of natural resources on a daily basis knowingly or unknowingly. While some of these are abundantly available in the atmosphere, most of these are fast depleting from earth. It is essential to use the natural resources wisely and stop any kind of wastage to ensure that these are available for our coming generations too. The government of every country must keep a check on the consumption of these resources and take measures to reduce wastage.

Natural Resources Essay – 5 (600 words)

Natural Resources are bliss for the mankind as well as other living organisms. These form an essential part of our lives. In fact, life on earth wouldn’t be possible without most of these natural resources.

Distribution of Natural Resources

Natural resources are distributed unevenly on Earth. Different parts of the planet are rich in different kinds of natural resources. While some places receive abundance of sunlight others remain devoid of the same for most part of the year. Similarly, while certain places have numerous water bodies others have rich mineral fields. There are many factors that influence uneven distribution of natural resources. Climate and land type are among the main factors.

Countries that boast of rich reserves of natural resources include China, Iraq, Venezuela, Russia, Saudi Arabia, United States of America, Canada and Brazil. Here is a look at the natural resources these countries are rich in:

Russia ranks number one when it comes to natural resources. The country boasts of abundance of timber, oil, natural gas, coal and gold. One of the main reasons of its economic growth is export of these valuable natural resources.

China has a rich reserve of coal, timber and various metals. It supplies these resources to various parts of the world.

Iraq is known to have a whopping 9% of the total world’s oil deposits. Besides oil, it is also rich in phosphate rock.

The country is rich in natural resources such as natural gas, iron and oil. It ranks six worldwide when it comes to oil reserves. It exports oil to many countries around the world.

• Saudi Arabia

The country encompasses the fifth largest natural gas reserve. Timber is also found in abundance in Saudi Arabia.

• United States

The United States comes on the second position when it comes to the availability of natural resources. It is known for its coal, natural gas and oil reserves and gold and copper deposits.

Canada comes on number four when it comes to the availability of natural resources. It is known for its oil deposits. It supplies oil to various countries worldwide. It is also known for its uranium, phosphate and natural gas reserves and timber production.

Brazil is the world’s second largest iron producer. It also generates a good amount of timber which is supplied to various countries worldwide. Besides, Brazil is known for its deposits of uranium and gold.

Similarly, different regions grow different kinds of fruits and vegetables and export them to other places. Same is the case with animals. All kinds of animals are not available everywhere. The raw materials they produce are thus exchanged between countries.

Impact of Uneven Distribution of Natural Resources

This uneven distribution of natural resources gives way to international trades which promotes businesses and boasts the economic growth of various countries around the world. However, it also has a downside to it. It has led to power play among the countries. Countries that have higher deposits of oil, natural gases, minerals and other natural resources control and exploit those that have fewer resources. Due to this the rich and developed countries are getting richer and the poor are getting poorer.

While natural resources are essential for us so much so that our life on earth is not possible without the existence of these resources, human beings are using these without any inhibition. They do not realise the fact that most of these resources are non-renewable and many others take thousands of years to renew. We must use natural resources wisely and avoid any kind of wastage to help our future generations enjoy the kind of comfort and luxury we enjoy.

Nature Essay for Students and Children

500+ words nature essay.

Nature is an important and integral part of mankind. It is one of the greatest blessings for human life; however, nowadays humans fail to recognize it as one. Nature has been an inspiration for numerous poets, writers, artists and more of yesteryears. This remarkable creation inspired them to write poems and stories in the glory of it. They truly valued nature which reflects in their works even today. Essentially, nature is everything we are surrounded by like the water we drink, the air we breathe, the sun we soak in, the birds we hear chirping, the moon we gaze at and more. Above all, it is rich and vibrant and consists of both living and non-living things. Therefore, people of the modern age should also learn something from people of yesteryear and start valuing nature before it gets too late.

Significance of Nature

Nature has been in existence long before humans and ever since it has taken care of mankind and nourished it forever. In other words, it offers us a protective layer which guards us against all kinds of damages and harms. Survival of mankind without nature is impossible and humans need to understand that.

If nature has the ability to protect us, it is also powerful enough to destroy the entire mankind. Every form of nature, for instance, the plants , animals , rivers, mountains, moon, and more holds equal significance for us. Absence of one element is enough to cause a catastrophe in the functioning of human life.

We fulfill our healthy lifestyle by eating and drinking healthy, which nature gives us. Similarly, it provides us with water and food that enables us to do so. Rainfall and sunshine, the two most important elements to survive are derived from nature itself.

Further, the air we breathe and the wood we use for various purposes are a gift of nature only. But, with technological advancements, people are not paying attention to nature. The need to conserve and balance the natural assets is rising day by day which requires immediate attention.

Conservation of Nature

In order to conserve nature, we must take drastic steps right away to prevent any further damage. The most important step is to prevent deforestation at all levels. Cutting down of trees has serious consequences in different spheres. It can cause soil erosion easily and also bring a decline in rainfall on a major level.

Polluting ocean water must be strictly prohibited by all industries straightaway as it causes a lot of water shortage. The excessive use of automobiles, AC’s and ovens emit a lot of Chlorofluorocarbons’ which depletes the ozone layer. This, in turn, causes global warming which causes thermal expansion and melting of glaciers.

Therefore, we should avoid personal use of the vehicle when we can, switch to public transport and carpooling. We must invest in solar energy giving a chance for the natural resources to replenish.

In conclusion, nature has a powerful transformative power which is responsible for the functioning of life on earth. It is essential for mankind to flourish so it is our duty to conserve it for our future generations. We must stop the selfish activities and try our best to preserve the natural resources so life can forever be nourished on earth.
