    How is coal formed? Socratic

    Coastal peat swamps build up over time, are buried by rising sea levels and eventually get compressed into coal. Coal starts off as vegetative matter that forms often in coastal regions. Over long periods of time, this plant material lives and dies and gradually builds up into thick peat deposits. Sea levels then often rise burying the peat and sediments are gradually laid on top of the peat.

    Coal formation Energy Education

    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.

    Coal mining Coal mining Coal deposits: In geologic terms, coal is a sedimentary rock containing a mixture of constituents, mostly of vegetal origin. Vegetal matter is composed mainly of carbon, hydrogen, oxygen, nitrogen, sulfur, and some inorganic mineral elements. When this material decays under water, in the absence of oxygen, the carbon content increases.

However, there are other uses for lignite as well.

    Coal explained U.S. Energy Information Administration (EIA)

    Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce. The rank of a coal deposit is determined by the amount of pressure and heat that acted on the plants over time.

    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.
