Formation of Coal
Overlaying of sediments over the burial results in the formation of fossil fuels due to exposure to high pressure for a very long period of time. The 3 main types of Fossil Fuels are Coal, Oil & Natural Gas. Natural coal is formed due to the burial of plants and animals. Petroleum and natural gas are a result of the buried marine life.
Coal
Origin of coal Coal-forming materials Plant matter. It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions.

How a Coal Plant Works
How a Coal Plant Works. Coal-fired plants produce electricity by burning coal in a boiler to produce steam. The steam produced, under tremendous pressure, flows into a turbine, which spins a generator to create electricity. The steam is then cooled, condensed back into water and returned to the boiler to start the process over.
