Coal is a fossil fuel extracted from the ground by mining.It is a form of carbon and hydrocarbons along with assorted other elements including sulfur.. Coal is a readily combustible black or brownish-black rock whose composition, including inherent moisture, consists of more than 50 percent by weight and more than 70 percent by volume of carbonaceous material.
This rock is a solid, but it is fragile and brittle. It is a carbonaceous black sedimentary rock which burns. This sedimentary rock is made up of hydrogen, carbon, oxygen, nitrogen, sulphur which is less important in this rock and other trace elements. Coal is divided into four classes: lignite, sub bituminous, bituminous, and anthracite. In ...

including mineral matter (James, 2005). Coal is a solid, brittle, combustible, carbonaceous rock formed by the decomposition and alteration of vegetation by compaction, temperature and pressure. It varies in color from brown to black and is usually stratified. Coal deposits, usually
Coal: A solid, brittle, more or less distinctly stratified combustible carbonaceous rock formed by partial to complete decomposition of vegetation; varies in color from dark brown to black; not fusible without decomposition and very insoluble.The classification of coal is done by degree of hardness, moisture and heat content. Anthracite is hard coal, almost pure carbon, used mainly for heating ...
Coal, one of the most important primary fossil fuels, a solid carbon-rich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in .
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. 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.
partially decomposed vegetation buried in a sedimentary environment may slowly be transformed into the solid brittle carbonaceous rock we call coll; world's most abundant fossil fuel lignite, bituminous, and anthracite. The high sulfur content of some types of coal pollute the atmosphere. Sulfur can be removed
