Fossil fuels are made from decomposing plants and animals. These fuels are found in Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usually found in sedimentary rock deposits where rock and dead plant and animal matter are piled up in layers. More than 50 percent of a piece of coal's ...

THE FORMATION OF COAL What is Coal? Coal is a combustible, sedimentary, organic rock formed from ancient vegetation, which has been consolidated between other rock strata and transformed by the combined effects of microbial action, pressure and heat over a considerable time. This process is referred to as 'coalification'.

When coal is heated strongly in the absence of air, a large number of organic and some inorganic compounds are formed. This process is called destructive distillation of coal. Two products of this process are coal tar and coal gas. Coal tar is a thick black liquid that is a byproduct of the destructive distillation of coal. It contains benzene ...

Answers (1) About 300 million year ago, Due to the natural calamities like flooding, storms and earthquake, the dense forests got buried under the soil. they were compressed, As more soil deposited over them. Under deep in the soil they were exposed to high pressure and high temperature, dead plants and animals slowly converted into coal.

Coal is a combustible rock mainly composed of carbon along with variable quantities of other elements, mostly hydrogen, sulphur, oxygen and nitrogen. Coal occurs as layers, called coal beds or coal seams, that are found between other sedimentary rocks. Coal is slightly denser than water but less dense than most of the rocks of the Earth's crust ...

Coal that is surfacemined is usually found in seams that range in size from 2 feet ( meter) to more than 100 feet (30 meters) thick. Some seams contain as much as 200,000 tons of coal in a single acre ( hectare). Normally, between 90 and 100 percent of this coal is recovered during surface mining operations.
