This coal seam in Scotland was originally a layer of sediment, rich in organic carbon. The sedimentary layer was eventually buried deep underground, and the heat and pressure transformed it into coal. Coal and other fossil fuels are a convenient source of energy, but when they are burned, the stored carbon is released into the atmosphere.Coal is a fossil fuel composed primarily of carbons and hydrocarbons. Its ingredients help make plastics, tar and fertilizers.A coal derivative, a solidified carbon called coke, melts iron ore and reduces it to create steel.But most coal -- 92 percent of the U.S. supply -- goes into power production [source: Energy Information Administration]. ...
