Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, 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.

There are several processes that contributed to the formation of coal, including: 1. Plant material accumulation: Coal was formed from the remains of plants that accumulated in swamps and wetlands. As these plants died, their remains fell into the water and began to accumulate in layers. 2. Peat formation: Over time, the plant material became ...

Abstract. The transformation of vegetable matter into peat and coal is commonly regarded as proceeding in two steps, called the biochemical and physicochemical stage of coalification (Stach et al. 1982), respectively. Other terms, such as "first and second phase" (Mackowsky 1953), or "diagenetic and metamorphic stage" (Teichmüller 1962 ...

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 classified as a sedimentary rock. It is a common nonrenewable fuel used mainly in the production of electricity. It is a fossil fuel because it forms from dead plant matter. The quality of coal depends on how it formed; as the organic matter is subjected to greater heat and pressure, the carbon content increases.

Coal is formed from the remains of plants, by a process called coalification. The whole process starts with the remains of dead plants, which must be buried in an oxygenpoor or oxygenfree environment, to avoid complete decomposition. Usually, these are swamptype environments. The coalification process takes place over millions of years.

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.

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.
