Formation of coal

Coal was formed from the dead remains of trees, ferns and other plants that lived 300 to 400 million years ago. Even swamps covered by sea water can also form coal . It is believed that dead plants were covered by rocks and soil and were decomposed by bacteria . Volcanic eruption and earth quakes destroyed forest which also got buried under the surface of the earth and in absence of air, they got converted into coal.
