Sedimentary rock - Coal | Britannica

Sedimentary rock - Sedimentary rock - Coal: Coals are the most abundant organic-rich sedimentary rock. They consist of undecayed organic matter that either accumulated in place or was transported from elsewhere to the depositional site. The most important organic component in coal is humus. The grade or rank of coal is determined by the percentage of carbon present.

Coal - Origin of coal | Britannica

Coal - Coal - Origin of coal: 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 low-lying 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 regions [e.g., Ireland and ...

What is coal used for? - USGS

Coal is primarily used as fuel to generate electric power in the United States. In coal-fired power plants, bituminous coal, subbituminous coal, or lignite is burned. The heat produced by the combustion of the coal is used to convert water into high-pressure steam, which drives a turbine, which produces electricity. In 2019, about 23 percent of all electricity in the United

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is 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.

Sep 20, 2019· 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. Learn more:

How Nature Makes Coal, Oil and Gas | EARTH 104: Earth and ...

Coal, as a solid, mostly sits where it was formed. Eventually, if the rocks above it are eroded so that it is exposed at the Earth's surface, the coal itself may be eroded away, and either "eaten" by bacteria, or buried in new rocks. And, occasionally, a natural forest fire or a lightning strike may set coal on fire.

How coal was formed. Coal was formed in Paleolithic era ecosystems ( lake basins, river deltas or low lying areas ) and is made of the material of prehistoric plants. Initially, through solar energy they produced hydrocarbons from air, water and mineral matters. Upon decay they sank into the swamps which were environments without oxygen.They could not decompose by normal biological processes.

Coal is a solid, black, readily combustible fossil fuel that contains a large amount of carbon-based material - approximately 50% of its weight. The formation of coal takes a significant amount of time (on the order of a few million years), and the first coal-bearing rock units appeared about 290-360 million years ago, at a time known as the Carboniferous or "coal-bearing" Period.
