The term "fossil fuel" applies to organic material deposits that can burn, thus producing energy. One such fuel is coal, which is the solid altered remains of plant material, while oil and gas are the liquid and gaseous remains of various organic or inorganic sources. Standard thinking requires long ages for their origin. For decades it has been taught that dead plants accumulate in the ...

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.

Coal forms from dead plants that sink to the bottoms of swamps. The organic matter is buried under sediments and slowly transformed into peat. If the peat is buried under more sediment, it can become coal. There are several kinds of coal. Coal that has experienced greater pressure contains more energy.

In the process of coal formation, first, the hydrogen is removed, then the nitrogen, and then the carbon. Carbon is most stable amongst hydrogen, nitrogen, and carbon. When the biochemical decomposition of vegetal matter happens, the result is carbon enrichment. Mode of Deposition of Coal. Let us understand the process of coal deposition in detail.

The formation of coal is a fourstage process, depending on the conditions to which the plant debris was subjected. More the heat and pressure to which vegetation is subjected, better is the quality of coal. Superior quality coal is denser, has more carbon content, contains lesser moisture and has a better calorific value. ...

Formation of coal : Coal is formed from the remains of the plants that existed in swampy forests some 200—300 million years ago. These plants got buried under the Earth due to some geological changes. As more and more materials piled on top of them, they were compressed. Coal is extracted from mines.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content.

The formation of peat is the first step in the formation of coal. With increasing depth of burial and increasing temperature, peat deposits are gradually changed to lignite. With increased time and higher temperatures, these lowrank coals are gradually converted to subbituminous and bituminous coal and under certain conditions to anthracite.
