What “coal” means
Wiktionary · Wikipediacoal/kɔʊl/
- nounA black rock formed from prehistoric plant remains, composed largely of carbon and burned as a fuel.
- verbTo take on a supply of coal (usually of steam ships).
Coal is a combustible black or brownish-black sedimentary rock, formed as layers called coal seams. Coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. It is a fossil fuel, formed when plants decay into peat which is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits formed from wetlands called coal forests that covered much of the tropics during the late Carboniferous and early Permian.
