Detailed explanation-1: -Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usually found in sedimentary rock deposits where rock and dead plant and animal matter are piled up in layers. More than 50 percent of a piece of coal’s weight must be from fossilized plants.

Detailed explanation-2: -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-3: -Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago. Because of their origins, fossil fuels have a high carbon content.

Detailed explanation-4: -Terrestrial plants tended to form coal and methane. Many of the coal fields date to the Carboniferous period of Earth’s history. Terrestrial plants also form type III kerogen, a source of natural gas.
