Coal is a fossil fuel, readily combustible black sedimentary rock normally occurring in rock strata in layers called coal beds. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly sulfur, hydrogen, oxygen and nitrogen. The largest reserves are found in the USA, Russia, China, India and Australia.
