Coal Plant Matter, Carbonization, Sedimentary Rocks

Coal Plant Matter, Carbonization, Sedimentary Rocks: It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in lowlying areas that remained wet most of the time and was converted to peat through the activity of microorganisms.

Peat occurs in sediments that are not yet hard enough to be called rock, lignite in soft sedimentary rocks, bituminous in harder ones, and anthracite in metamorphic rocks. Oil is formed from "slimy" water plants (algae, plus things such as cyanobacteria that probably shouldn't really be called plants, but we're simplifying a little here).
