Coal is composed of macerals, minerals and water. Fossils and amber may be found in coal. Formation. Example chemical structure of coal. At various times in the geologic past, the Earth had dense forests in low-lying wetland areas. Due to natural processes such as flooding, these forests were buried underneath soil. As more and more soil ...


Coal is a fossil fuel and is the altered remains of prehistoric vegetation that originally accumulated in swamps and peat bogs. The energy we get from coal today comes from the energy that plants absorbed from the sun millions of years ago.


What is Coal made of? April 25, 2011, cherran, Leave a comment. What is Coal made of? Coal is made from trees or plants that decayed on the ground for millions of years. The remains of various plants and trees then mixed with the other components of the ground and eventually going through several natural processes making them more like solid rocks.


Coal is made out of residue of trees and plants from millions of years ago through combined effects of pressure and heat. It is a sedimentary, organic and combustible rock composed mainly of carbon, oxygen and hydrogen. Coal is more plentiful than oil or natural gas and is mainly used to produce electricity and heat through combustion.


anthracite- it has the most carbon and the least amount of moisture. moisture is made of hydrogen and oxygen. the less moisture the coal has the less chance that the carbon can mix with hydrogen and oxygen, creating less of a chance for greenhouse gas emissions.


coal contains Carbon, hydrogen sulfur, oxygen and nitrogen. We use it as a fuel in power plants.industrial furnaces.domestic cooking etc. It is mostly used in huge boilers to make steam and used for electrical power generation Olden times team engines and steam loco motives were using coal.. some type of good coal is used in blast furnace to make steel.


Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams. Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Hope this helps.


Coal [1] Coal is a naturally occurring combustible material consisting primarily of the element carbon. It also contains low percentages of solid, liquid, and gaseous hydrocarbons and/or other materials, such as compounds of nitrogen and sulfur.


Coal is a combustible, sedimentary, organic rock, which is composed mainly of carbon, hydrogen and oxygen. It is 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 room-and-pillar method involves leaving large pillars spaced at regular intervals in each seam to support the ceiling. At each level where coal is present, the wells are linked to a network of huge galleries (10-20m2 sections) that can extend over dozens of kilometers.
