Question

explain the formation of coal.​

Answer 1

Answer:

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. ... Some iron and steel making and other industrial processes burn coal. The extraction and use of coal causes many premature deaths and much illness.

Answer 2

Explanation:

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] However, many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras.
