Coal is a sedimentary rock that is made up mostly of organic matter; forms by accumulating large quantities of plant remains. In successive stages, higher temperatures rid coal of impurities. Forms in swamps because of the water''s oxygen deficient.
If there is a layer of rock above the coal face, called the overburden, this is also removed before the coal can be excavated. Once all the coal has been removed, the overburden and topsoil are replaced to help in restoring the natural vegetation of the area. This is called rehabilitation.
