How is coal formed?

2018-1-5  Coal formed millions of years ago when the earth was covered with huge swampy forests where plants giant ferns, reeds and mosses grew. As the plants grew, some died and fell into the swamp waters. New plants grew up to take their places and when these died still more grew. In time, there was thick layer of dead plants rotting in the swamp.

How is coal formded? Kentucky Geological Survey

Coal is formed from the physical and chemical alteration of peat. Peat is composed of plant materials that accumulate in wetlands ( bogs and fens), which break down through the process of peatification. If peats are buried, then the peats can be altered into different ranks of coal through the process of coalification.

How Was Coal Formed? Before starting, we must remember that our earth is approximately 4.5 billion years old. And its coal reserves we formed over a span of millions of years as plant remains got buried under the ground and were subjected to immense pressure and heat over the years before they finally turned into rocks.

The increased pressure was caused by more dock deposits that formed bituminous coal. In areas where mountains are formed, the coal beds had been compressed to the hardest type of coal that was recognized as anthracite.

Coal Types, Uses and Formation

On burning coal, coal ash is formed. This coal ash comprises several minerals like calcium and aluminium, which can be reused. About 40% of coal ash produced each year is effectively reused to fill coal mines that are abandoned. Sometimes, coal ash is used as the topmost layer on roads and foundations of high rise buildings.
