What is called natural resources?
Without human assistance, natural resources are present on planet. We can get water, wood, food, and energy from natural resources. Without natural resources, life is not conceivable.Oil, coal, natural gas, metals, stone, and sand are examples of natural resources. Other natural resources include water, soil, sunlight, air, and so on.
Types of Natural resources:
two types of natural resources.
2.non renewable resources.
A resource that can be used repeatedly and does not run out because it is naturally replaced.
examples of renewable resources are:
One well-known renewable resource is sunlight. In fact, throughout human history, it has been used to heat water, dry and prepare food, and warm habitations. In order to gather and transform solar radiation into heat energy that can be used for a variety of purposes, different technologies already exist and are being developed.
The sun and wind are in a direct interaction. When the sun’s heat is absorbed unevenly by the various surfaces of the earth, including oceans and other water masses, daily winds are created. When the sun is shining during the day, air above land warms up more quickly than air above water. The warm air rises and expands. It is replaced with cooler air. The result is wind.In earlier years, windmills were used across the U.S. to capture energy and pump water from wells. They still exist in some farming areas to provide livestock with water.
Geothermal energy uses the heat of the earth to produce electricity and is a renewable resource. For millennia, people have taken baths in hot springs that are heated by the ground. District heating systems have also utilised and continue to employ geothermal energy. Moreover, geothermal energy is used to produce power. Underground power plants are constructed for this purpose within a mile of the earth’s surface.
A dam or other construction that alters the natural flow of a river or other body of water is used to generate hydropower, often known as hydroelectric power.Water in motion generates hydroelectricity, namely the winter and spring runoff from mountain streams and crystal-clear lakes. Water can be utilised to turn turbines and generators that produce power when it is falling due to gravity.
Tidal energy is a renewable source of power generated by the tidal movements and ocean currents that occur naturally. These technologies include paddles and turbines, among others. The rush of ocean waters during tide changes is what generates tidal energy. A renewable energy source is tidal energy.
A clean, renewable energy source is biomass. Plant or algae biomass may regenerate quickly since it receives its initial energy from the sun. Municipal solid trash, trees, and crops are all readily available and may be managed responsibly.
Advantages of renewable resources:
2.clean,safe and efficient
3.numerous methods to create renewable power
4.Reliability and resilience
5.Less global warming.
Disadvantages of renewable resources:
1.Renewable resources need recycling.
2.initial cost is very high
3.renewable resources is not available at any time
4.It is difficult to generate the quantity of electricity.
Non Renewable resources:
The sources of non-renewable energy will deplete or not be renewed within our lifetimes, or perhaps within many, many lifetimes.
Examples of non renewable resources are:
1.Fossil fuels: coal, crude oil, natural gas
A flammable sedimentary rock with a high concentration of carbon and hydrocarbons, coal is often black or brownish-black in colour. Because it takes millions of years for coal to develop, it is categorised as a nonrenewable energy source. Coal is made up of the energy that was once locked up in plants that inhabited marshy forests hundreds of millions of years ago.
Only one non-renewable resource, crude oil, commonly known as petroleum oil, is extracted in liquid form. It is extracted by drilling a vertical well into the ground or ocean floor and is discovered between the layers of the earth’s crust or between rocks.
There are no renewable energy sources like natural gas. It takes millions of years for a fossil fuel to form. We can only manufacture more till a finite amount of it remains in the ground.
The element uranium is the one that is most frequently employed in nuclear power reactors. Despite the fact that uranium may be found in rocks all over the world, nuclear power plants typically use U-235, a highly uncommon form of uranium. A non-renewable resource is uranium. Over the world, generating power via nuclear energy is a common practise.
Advantages of non renewable resources:
1.Non renewable resources are abundant and affordable
2.it is more effective and easier to produce and use then renewable energy
3.Non renewable resources are significant source of energy.
Disadvantages of non renewable resources:
1.These resources are used once.it can not be replaced.
2.once fossil fuels are burn.it creates pollution.
3.heavy uses of fossil fuels .it creates global warming and green house effect.
