Answer:
Because coal takes millions of years to develop and there is a limited amount of it, it is a nonrenewable resource. The conditions that would eventually create coal began to develop about 300 million years ago, during the Carboniferous period.

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
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.
