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.

Answers (1) About 300 million year ago, Due to the natural calamities like flooding, storms and earthquake, the dense forests got buried under the soil. they were compressed, As more soil deposited over them. Under deep in the soil they were exposed to high pressure and high temperature, dead plants and animals slowly converted into coal.

Coal that is surfacemined is usually found in seams that range in size from 2 feet ( meter) to more than 100 feet (30 meters) thick. Some seams contain as much as 200,000 tons of coal in a single acre ( hectare). Normally, between 90 and 100 percent of this coal is recovered during surface mining operations.

Describe how coal is formed from dead vegetation .What is this process called. The formation of coal begins in areas of swampy wetlands where groundwater is near or slightly above the topsoil.

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.

When these died, they too got covered. Sometimes earthquake and volcanoes buried entire forests deep down in the earth. The high temperature and high pressure inside the earth slowly converted the buried vegetation into coal. A coal contains mainly carbon. Thus, this slow process of conversion of wood into coal is called carbonization.

For example, coal, petroleum and natural gas are fossil fuels. Coal was formed by the process of carbonisation. Carbonisation is the process by which plant material or vegetation buried deep under the earth was slowly converted into coal. Question 25. Describe how coal was formed. What is this process called? Answer:

When coal is heated strongly in the absence of air, a large number of organic and some inorganic compounds are formed. This process is called destructive distillation of coal. Two products of this process are coal tar and coal gas. Coal tar is a thick black liquid that is a byproduct of the destructive distillation of coal. It contains benzene ...

Solution. Verified by Toppr. Coal is 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. Some iron and steel making and other industrial processes burn coal. The extraction and use of coal cause many premature deaths and many illnesses.

What is this process called? Coal was formed millions and millions of years ago in swampy forests where some plants died and some grew simultaneously. As the years passed, the layers of dead plants collected one over the other and formed thick layers. With changing weather conditions, more plants grew and the layers of dead plants continued to ...

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...

coal produced in the United States is subbituminous. Wyoming is the leading source of subbituminous coal. Bituminous coal contains 4586 percent carbon, and has two to three times the heating value of lignite. Bituminous coal was formed under high heat and pressure. Bituminous coal in the United States is between 100 to 300 million years old.

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.

The slow process by which the dead plants buried under the Earth have become coal is called as carbonisation. Since coal was formed from the remains of the plants, it is called a fossil fuel. Coal, which is mainly carbon, on heating produces mainly carbon dioxide gas and a lot of heat energy.
