Coal is the compacted and preserved remains of plant matter. Although most plant matter decomposes where it falls, when plant life containing celluloserich stems and leaves is highly abundant and special conditions exist, the plant matter does not totally decompose and is preserved in fossilized form.

The process of removing coal from the ground is known as coal mining. Coal mining can take place underground or at the surface. The process of coal mining, especially surface mining, affects the environment. ... How does a fossil fuel form? The hardest type of coal is called anthracite. Why is anthracite harder than other kinds of coal?

coal with a controlled amount of oxygen, a process called pyrolysis. Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the use of coal oil in the 20th century. Coking coal is used in largescale industrial processes. The coal is coked, a process of heating the rock in the

The process of coal formation is called carbonisation. The dead plants and vegetation due to temperature and high pressure over hundreds of years slowly turned into coal. This slow conversion of dead plants and forests into coal is called the process of carbonisation. The process is called so because coal largely contains carbon.

Process of Formation of Coal. Coal formed under somewhat more moderate conditions are called bituminous coals. These coals are found in flat or gently sloping seams, indicating that the strong geologic pressures operative in the formation of anthracite were not operative during formation of bituminous coal.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

Coal Plant Matter, Carbonization, Sedimentary Rocks: 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. (It should be noted that peat can occur in temperate ...

This process is called carbonization. So, carbonization can be defined as the slow process in which the dead plants and trees under the surface of the earth in high pressure and temperature form coal. It is called fossil fuels because it is formed by the dead remains of plants. So, when coal is heated it forms carbon dioxide and heat energy.

Most of the coal burned in US power plants is bituminous or subbituminous coal. A fifth type, called metallurgical (or "coking") coal, is used for steelmaking. All types of coal also contain sulfur, which, when burned, releases toxic air pollution. Sulfur content is determined by the conditions under which the coal is formed.

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.
