Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal seams al is mostly carbon with variable amounts of other elements chiefly hydrogen, sulfur, oxygen, and nitrogen. 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.
