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.

71,757 How is Coal Formed? The formation of coal takes millions of years, which is why it is an exhaustible and nonrenewable natural resource. It was formed around 300 million years ago when the earth was covered with swampy forests. When plants in these forests mainly trees, mosses, ferns, and reeds died, they fell into the swamps.

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...

Ans. Carbonization is a process of the formation of coal. As coal is formed by decaying vegetation under heat and pressure, the dead plants gradually turn into coal. This conversion of dead plants into coal is a process called carbonization. Peat is the inferior variety of coal. It contains a high amount of moisture and less than 40% of carbon.

Step 3. If you know the potential energies for the forces that enter into the problem, then forces are all conservative, and you can apply conservation of mechanical energy simply in terms of potential and kinetic energy. The equation expressing conservation of energy is. [KE_i + PE_i = KE_f + PE_f.] Step 4.

Coal oil is made by heating cannel 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 slow process of conservation of dead vegetation into coal is called Carbonisation. Since it was formed from the remain of vegetation, coal is also called a fossil fuel. When heated in air, coal burns and produces mainly carbon dioxide gas. Coal is processed in industry to get some useful products such as coke, coal tar, coal gas.
