Describe how coal is formed from dead vegetation. What is this process called?
Millions of years ago, dense forests got buried under the soil due to natural processes like storms, floods, and earthquakes. These got compressed as more and more soil got deposited over them. When they got buried deep in the soil, they were exposed to very high pressure and temperature. Under these conditions, they slowly got converted into coal. This process of formation of coal from dead vegetation is called carbonisation.
