  • The Formation of Fossil Fuels

    Coal forms from dead plants that sink to the bottoms of swamps. The organic matter is buried under sediments and slowly transformed into peat. If the peat is buried under more sediment, it can become coal. There are several kinds of coal. Coal that has experienced greater pressure contains more energy.
