Coal is formed whendead 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,low-carbon peat,to coal,an energy- and carbon-dense black or brownish-black sedimentary rock.

What is coal and how is it formed?
How is coal formed? Coal is a fossil fuel, formed from vegetation, which has been consolidated between other rock strata and altered by the combined effects of pressure and heat over millions of years to form coal seams. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago.
How is coal made into smokeless coal?
To manufacture smokeless coal, firstly, the naturally occurring anthracite is ground down into powder before being re-formed into briquettes of even form by combining the powder with a smokeless binding agent such as starch or molasses. These formed briquettes are more versatile than natural anthracite…
How is coal used to make steel?
Steel is an essential material for modern life and global steel production is dependent on coal – 70% of steel produced uses coal. Metallurgical coal 鈥?or coking coal 鈥?is a vital ingredient in the steel making process. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed.
What is the main source of energy in coal?
It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States. Fossil fuels are formed from the remains of ancient organisms.
