Detailed explanation-1: -Coal is called a fossil fuel because it was made from plants that were once alive! Since coal comes from plants, and plants get their energy from the sun, the energy in coal also came from the sun. The coal we use today took millions of years to form.

Detailed explanation-2: -There are three types of fossil fuels which can all be used for energy provision; coal, oil and natural gas.

Detailed explanation-3: -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-4: -What are fossil fuels? Fossil fuels are formed from the decomposition of buried carbon-based organisms that died millions of years ago. They create carbon-rich deposits that are extracted and burned for energy. They are non-renewable and currently supply around 80% of the world’s energy.

Detailed explanation-5: -Chemical energy is energy stored in the bonds of atoms and molecules. Batteries, biomass, petroleum, natural gas, and coal are examples of chemical energy.
