Explanation
Coal is a commodity regarded as a fossil fuel that is not renewable. It’s the most fossil fuel we’ve got. The four types of coal are peat, lignite, bituminous, and anthracite, with the high heat content of anthracite being the most desirable.
First Stage – Peat
This is the first stage in the formation of coal. It is an organic substance that is formed due to the partial decomposition of dead matter. The partial decomposition is due to the accumulation of the matter underwater, which cuts off the oxygen supply.
Second Stage – Lignite
Coal formation is the second stage. It is a dark brown matter formed due to the pressure exerted by the sediments overlying the organic matter. It consists of traces of plants.
Third Stage – Bituminous Coal
This is the third stage in the formation of coal. It is formed due to the added pressure. This is also called soft coal.
Fourth Stage – Anthracite Coal
It is formed due to high pressure and high temperature for a long period of time. It is hard, lustrous and has the highest percentage of carbon among peat, lignite, bituminous and anthracite. This is also called hard coal.
Uses of Coal
- It is mainly used to generate heat and electricity.
- It is used in households and in industries to accomplish various tasks.
- It is the cheapest source of power fuel.
- The iron and steel industry depends heavily on fossil fuels for energy.
