Question

Whre do we get coal from and how is it formed?

Answer 1

We can find coal mostly from forests. They are dead remains of organisms . when they are burnt coal is formed. It is a fossil fuel.

Answer 2

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.
