Solution

About 300 million years ago the earth had dense forest in low lying wetland areas. Due to natural processes, like earthquakes, these forests got buried under the earth’s surface. As more soil deposited over them, they were compressed. The temperature also rose as they sank deeper and deeper. Under high temperature and high pressure, dead plants got slowly converted into coal.
