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'.

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.

The formation of coal occurs over millions of years via a process known as carbonation. In this process, dead vegetation is converted into coal which is found to be carbonrich under very high temperature and pressure. Coal is also called as black gold. Now let's discuss about how coal is formed. The formation of coal occurs over ...

Most of the coal burned in US power plants is bituminous or subbituminous coal. A fifth type, called metallurgical (or "coking") coal, is used for steelmaking. All types of coal also contain sulfur, which, when burned, releases toxic air pollution. Sulfur content is determined by the conditions under which the coal is formed.

This process is called carbonization. So, carbonization can be defined as the slow process in which the dead plants and trees under the surface of the earth in high pressure and temperature form coal. It is called fossil fuels because it is formed by the dead remains of plants. So, when coal is heated it forms carbon dioxide and heat energy.

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]

Coal is formed from dead vegetation through a process called carbonization. This process involves the transformation of plant material into coal due to the pressure and heat exerted on it over millions of years. The process begins with the accumulation of dead plant matter in swamps and marshes, where it is buried under layers of sediment.
