Explain the process of formation of coal.
Answers
Answer:
Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. ... As a fossil fuel burned for heat, coal supplies about a quarter of the world's primary energy and two-fifths of its electricity.
Answer:
About 300 million years ago the earth had dense forests in low lying wet land areas . Due to natural processes , like flooding,these forests got buried under the soil . As more soil deposited over them,they were compressed . The temperature also raise 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 carbonisation. Since it was formed from the remains of vegetation , coal is also called a fossil fuel
