Introduction to Coal ;
Coal is a combustible black or brownish-black sedimentary rock, formed as a result of plant matter being converted into peat, and then converted into lignite, bituminous coal, or anthracite.
Coal is a combustible black or brownish-black sedimentary rock, formed as a result of plant matter being converted into peat, and then converted into lignite, bituminous coal, or anthracite. Coal is mainly used as a fuel for steam-electric power generation, as well as for heat and power applications in manufacturing and mining. Coal is also used to produce coke, which is an essential ingredient in the manufacture of steel.
The extraction of coal from the ground by mining is a very important industry. Coal is an important source of energy for the United States. The burning of coal produces emissions of carbon dioxide (CO2), sulfur dioxide (SO2), and nitrogen oxides (NOx), which contribute to environmental problems such as acid rain and smog.
Coal is a fossil fuel that is used to produce energy. It is a combustible black or brownish-black sedimentary rock that is composed mostly of carbon and hydrocarbons. Coal is the most abundant fossil fuel in the United States.
Uses and Origin of Coal
Coal is a sedimentary rock that is composed of carbon and other elements. It is black or dark brown in color and has a high carbon content. Coal is a fossil fuel and is used to produce energy. It is the most abundant fossil fuel in the world.
Coal was formed over millions of years from the remains of plants and animals. The plants and animals were buried under sediment and the pressure and heat of the earth caused the carbon to combine with other elements to form coal.
Coal is used to produce energy. It is burned to create heat which is used to generate electricity. Coal is also used to produce coke which is used in the steelmaking process.
The use of coal has a negative impact on the environment. Coal burning produces air pollution which can cause health problems. Coal mining can also have a negative impact on the environment.
