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 ...

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 formed by decomposition of living organisms which lived million years ago. Million years ago, plants and animals lived in a swampy forest. After the animals and plants died, other plants and animals grow instead of earlier organisms. The dead organisms form rot and form a layer of decaying things. After sometimes, water and light stop ...

The formation of coal takes millions of years, which is why it is an exhaustible and nonrenewable natural resource. It was formed around 300 million years ago when the earth was covered with swampy forests. When plants in these forests mainly trees, mosses, ferns, and reeds died, they fell into the swamps. And this process is called ...

Origin of coal Coalforming materials Plant matter. It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in lowlying areas that remained wet most of the time and was converted to peat through the activity of microorganisms. (It should be noted that peat can occur in temperate ...

Coal Geology. Coal is a combustible sedimentary 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 period. This process is commonly called 'coalification'. Coal occurs as layers or seams, ranging in ...
