Coal is formed from the remains of plants, by a process called coalification. The whole process starts with the remains of dead plants, which must be buried in an oxygenpoor or oxygenfree environment, to avoid complete decomposition. Usually, these are swamptype environments. The coalification process takes place over millions of years.

Geology Coal is composed of macerals, minerals and water. [18] Fossils and amber may be found [where?][by whom?] in coal. Formation Example chemical structure of coal The conversion of dead vegetation into coal is called coalification. At various times in the geologic past, the Earth had dense forests [19] in lowlying wetland areas.

It is the coal with the lowest carbon content. The carbon content is only about 6070 %. It is formed during the younger stages of coal formation and thus has a lower carbon content. Due to the less amount of carbon, it is not fully black in colour and is somewhat brown. Lignite is used in electricity generation and in fertilizer production.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content. There are four ...

Plant matter 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 lowlying areas that remained wet most of the time and was converted to peat through the activity of microorganisms.

Coal miners use two primary methods to remove coal. Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. Mountaintop removal is a form of surface mining where the tops of mountains are removed to access coal seams.

Coal is a rock formed mainly by carbon and other substances, it is used as an energy source and can be of vegetable or mineral origin. Its origin occurs in the Carboniferous period of the Paleozoic era as a result of the death of the immense forests of ferns and horsetails that died and were buried in the swamps they inhabited, the lack of oxygen, pressure, water and mud prevented There was a ...

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.

Earth Science Coal is a fossil fuel that has been used for several hundred years. Most people have heard of coal and know that the Earths coal supplies are limited but they may not know how coal was formed. There are some mistaken beliefs that coal comes from the remains of long extinct dinosaurs but this is not true.

Let us understand the process of coal deposition in detail. Coal is formed mainly from the terrestrial plant material that grows on dry land. The plant debris gets transported by water and then gets deposited under the water in the water bodies. The sediments organic and inorganic, get settled down gradually.

Uses of Coal. It is mainly used to generate heat and electricity. It is used in s and in industries to accomplish various tasks. It is the cheapest source of power fuel. The iron and steel industry depends heavily on fossil fuel for energy. It is also used to produce useful products such as coke, tar, and coal gas.

Due to high pressure and temperature inside the earth,and in the absence of air,the woods of buried trees was slowly converted into soil. The slow process by which the dead plants buried deep under the earth have become coal is called Carbonisation. Since coal was formed from remains of plants therefore coal is called a fossil fuel.

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.

Coal formed millions of years ago when the earth was covered with huge swampy forests where plants giant ferns, reeds and mosses grew. As the plants grew, some died and fell into the swamp waters. New plants grew up to take their places and when these died still more grew. In time, there was thick layer of dead plants rotting in the swamp.
