Introduction Coal is classified as a sedimentary rock. It is a common nonrenewable fuel used mainly in the production of electricity. It is a fossil fuel because it forms from dead plant matter. The quality of coal depends on how it formed; as the organic matter is subjected to greater heat and pressure, the carbon content increases.

Use this printable infographic to learn about the rock cycle. There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing ...

Coal was formed by the decomposition of large land plants and trees buried under the earth 300 million years ago. The slow process by which the dead plants buried deep under the earth have become coal is called Carbonisation. Since coal was formed from remains of plants therefore coal is called a fossil fuel.

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]

It is the coal with the lowest carbon content. The carbon content is only about 6070 %. It is formed during the younger stages of coal formation and thus has a lower carbon content. Due to the less amount of carbon, it is not fully black in colour and is somewhat brown. Lignite is used in electricity generation and in fertilizer production.

What is coalification process?

What is coalification process?

Answer: Coal is formed when peat is changed physically and chemically. Thisprocess is called coalification. During this process peat undergoes many changes as a result of bacterial decay,heat, and time. Peat deposits contain everything from pristine plant parts,such as roots, bark, spores, etc.

Coal formed millions of years ago when the earth was covered with huge swampy forests where plants giant ferns, reeds and mosses grew. As the plants grew, some died and fell into the swamp waters. New plants grew up to take their places and when these died still more grew. In time, there was thick layer of dead plants rotting in the swamp.

Coal miners use two primary methods to remove coal. Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. Mountaintop removal is a form of surface mining where the tops of mountains are removed to access coal seams.

Due to natural processes like flooding, these forests got buried under the soil. As more soil was deposited, they were compressed. With an increase in depth, the temperature also rises. Under high pressure and high temperature, dead plants got slowly converted into coal. The process of coal formation is very slow and might take millions of years.

Let us understand the process of coal deposition in detail. Coal is formed mainly from the terrestrial plant material that grows on dry land. The plant debris gets transported by water and then gets deposited under the water in the water bodies. The sediments organic and inorganic, get settled down gradually.

However, petroleum, like coal and natural gas, is a nonrenewable source of energy. It took millions of years for it to form, and when it is extracted and consumed, there is no way for us to replace it. Oil supplies will run out. Eventually, the world will reach " peak oil," or its highest production level. Some experts predict peak oil ...
