Detailed explanation-1: -Fossil fuels like coal, petroleum, and natural gases take millions of years for their formation. If these fuels are exhausted today, then they will not be formed very soon. Hence, they are known as non-renewable sources of energy.
Detailed explanation-2: -These layers were subjected to heat and pressure over millions of years. The sediments were transformed into beds of rock, and the plant and animal remains underwent slow chemical change and formed oil and natural gas. As you can see, the fossil fuels take millions of years to form. They cannot be replaced quickly.
Detailed explanation-3: -Fossil fuels are available in limited amount and can be exhausted by human activities. Moreover, they can’t be renewed fast enough. Therefore, they are considered as non-renewable resources.
Detailed explanation-4: -FOSSIL FUELS FORM. After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal. Today, humans extract these resources through coal mining and the drilling of oil and gas wells on land and offshore.
Detailed explanation-5: -There are four major types of nonrenewable resources: oil, natural gas, coal, and nuclear energy. Oil, natural gas, and coal are collectively called fossil fuels. Fossil fuels were formed within the Earth from dead plants and animals over millions of years-hence the name “fossil” fuels.
