Coal is an organic sedimentary rock. Coal is formed by the biogenic and thermal decomposition of vegetal matter. When plants remains are buried underneath,the decompose and convert to peat through biogenic and thermogenic processes.
Sedimentary rocks are actually formed by sediment. It is piled up over time, usually in layers at the bottom of the ocean or even lakes. The sediment can include all sorts of things like minerals, bits of plants, shells, corals and algae and all sorts of other weird and wonderful things.
From the Latin sedimentum - settling. Sedimentary rocks make up only 5% (by volume) of the upper 10 miles of the crust, but about 75% of the outcrops on the continents.
