EVERYDAY SCIENCE

Detailed explanation-1: -Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs.

Detailed explanation-2: -Fossil energy sources, including oil, coal and natural gas, are non-renewable resources that formed when prehistoric plants and animals died and were gradually buried by layers of rock.

Detailed explanation-3: -Fossil fuels are all nonrenewable. But not all nonrenewables are fossil fuels. Crude oil, natural gas, and coal are all considered fossil fuels, but uranium is not. Rather, it is a heavy metal that is extracted as a solid and then converted by nuclear power plants into a fuel source.

Detailed explanation-4: -Fossil fuels like coal and petroleum are formed from the decayed plants and animals buried under the Earth. It takes millions of years for them to decay and convert into fossil fuels. So, fossil fuels like coal, petroleum, etc cannot be replenished easily and hence, it is considered as a non-renewable source of energy.

Detailed explanation-5: -Nuclear energy (Uranium) Apart from fossil fuels, the other category of non-renewable resources is nuclear fuels. It is primarily obtained through the mining and refining of uranium ore, a naturally occurring radioactive element below the earth’s surface.
