Coal forest - Wikipedia

Coal forests were the vast swathes of wetlands that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian) and Permian times. As vegetable matter from these forests decayed, enormous deposits of peat accumulated, which later changed into coal.. Much of the carbon in the peat deposits produced by coal forests came from photosynthetic splitting of existing ...

How Nature Makes Coal, Oil and Gas | EARTH 104: Earth and ...

Coal, as a solid, mostly sits where it was formed. Eventually, if the rocks above it are eroded so that it is exposed at the Earth's surface, the coal itself may be eroded away, and either "eaten" by bacteria, or buried in new rocks. And, occasionally, a natural forest fire or a lightning strike may set coal on fire.
