the technicalities of coal
Coal
Coal is a combustible black or brownishblack 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 Coal is a type of fossil fuel, 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 Vast deposits of cThere are four major types (or “ranks”) of coal Rank refers to steps in a slow, natural process called “coalification,” during which buried plant matter changes into an ever What are the types of coal?
