Question

How Coal was formed??????

Answer 1

coal is formed by sedimentary rocks.it takes many years 2 form.under high pressure and temperature these rocks r changed into coal

Answer 2

the plants in large and dense forests in low lying wetlands got buried under the soil due to the natural processes like floods and earthquakes. As more soil deposited over them, the organic matter was compressed. The temperature also rose. As the organic matter sank deeper and deeper, under high pressure and high temperature, these dead plants slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Since coal is formed from the remains of vegetation, it is also called Fossil Fuel
