Answer» Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen.[1] Coal is formed when dead plant matter decays into PEAT and is converted into coal by the heat and pressure of deep burial over millions of years.[2] VAST deposits of coal originate in former wetlands—called coal forests—that covered much of the Earth's tropical land areas during the LATE CARBONIFEROUS (Pennsylvanian) and Permian TIMES.[3][4]Coal, please mark as brainliest answer it took so much of time |
