Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.

Other articles where coalification is discussed: coal: Peat: The process of peat formation—biochemical coalification—is most active in the upper few metres of a peat deposit. Fungi are not found below about metre (about 18 inches), and most forms of microbial life are eliminated at depths below about 10 metres (about 30 feet). If either the rate of.

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 seams may also contain methane (CH 4), which can be produced in conjunction with CO 2 injection in a process called enhanced coal bed methane (ECBM) recovery (see depiction below). In coal seams, the injected CO 2 can be chemically trapped by being adsorbed (or adhered) to the surface of the coal while CH 4 is released and produced.

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 ...
