Coal formed millions of years ago when the earth was covered with huge swampy forests where plants giant ferns, reeds and mosses grew. ... Heat and pressure produced chemical and physical changes in the plant layers which forced out oxygen and left rich carbon deposits. Advertisement.

As more soil got deposited over them, they were compressed. The temperature also rose as they sank deeper and deeper. Under high pressure and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonization.

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 ...

Coal is a nonclastic sedimentary rock. They are the fossilized remains of plants and are in flammable black and brownishblack tones. Its main element is carbon, but it can also contain different elements such as hydrogen, sulfur and oxygen. Unlike coal minerals, it does not have a fixed chemical composition and crystal structure.

Heat, time, pressure, and coalification. Heat: Heating is the primary control on coalification and rank increases in coal. On average, heat in the earth rises 1 degree Fahrenheit per 70 to 100 feet of depth. The deeper a coal is buried in a subsiding basin, the higher its rank. Heating during burial can also occur through interaction with ...

How Natural Gas Is Formed. Natural gas is a fossil fuel, like oil and coal, which releases pollution and global warming emissions when burned. Methane, the primary component of natural gas (or just "gas"), is itself a potent global warming pollutant, more than 80 times more powerful than carbon dioxide over a 20year period. Like oil, gas is a ...

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.

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.
