Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.

slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Since it was formed from the remains of vegetation, coal is also called a fossil fuel. A coal mine is shown in Fig. COAL AND PETROLEUM 33 Rationalised202324

Carbon (from Latin carbo 'coal') is a chemical element; it has symbol C and atomic number 6. It is nonmetallic and tetravalent —meaning that its atoms are able to form up to four covalent bonds due to its valence shell exhibiting 4 electrons. It belongs to group 14 of the periodic table. [14]

There is thought to be 4 processes that lead to diamond formation. The first of the four processes is the most significant. 1. Earth's Mantle Geologist believe that diamonds form in the Earth's mantle and are transported the the Earth's surface by deepsource volcanic eruptions. The diamonds form from pure carbon in the mantle under ...

Ever wonder where a "fossil fuel" gets its name? Fossil fuels are compound mixtures made of fossilized plant and animal remnants from millions of years ago. The creation of fossil fuels—either oil, natural gas, or coal—from these fossils is determined by the type of fossil, the amount of heat, and the amount of pressure.

Due to natural processes like flooding, these forests got buried under the soil. As more soil was deposited, they were compressed. With an increase in depth, the temperature also rises. Under high pressure and high temperature, dead plants got slowly converted into coal. The process of coal formation is very slow and might take millions of years.

Coking coal is used in largescale industrial processes. The coal is coked, a process of heating the rock in the absense of oxygen. This reduces the moisture content and makes it a more stable product. The steel industry relies on coking coal. Bituminous coal accounts for almost half of all the coal that is used for energy in the United States.
