How is coal formed?
Hint: Coal is fossil fuel or we can say, fuel that comes from the remains of dead plants or animals. The formation of coal occurs over millions of years via a process known as carbonation. In this process, dead vegetation is converted into coal which is found to be carbon-rich under very high temperature and pressure.
How are dead remains of plants converted into coal?
Dead remains of plants got buried under the earth millions of years ago. Due to intense heat and pressure inside the earth, they got converted into coal. The process of conversion of dead remains of plants into coal is called carbonization. Our earth had dense forests in low-lying wetland areas about 300 million years ago.
What is the main use of coal?
The main use of coal is as fuel for electric power plants, for which more than 50% of the coal produced in the world is used. The simplest use of coal is to burn it for heat.
How did the forest get buried under the soil?
Millions of years ago, dense forest got buried under the soil due to natural processes like storms, floods and earthquakes etc. These got compressed or more and more layer of soil got deposited over them. When they got deep burried in the layers of soil, they were exposed to very high pressure and high temperature.
