Coal
The main constituents of coal are- carbon, hydrogen, oxygen and small amounts of sulphur and nitrogen. Coal is obtained by mining and occurs deep inside the Earth. It is now believed that the changes in the Earth's crust might have buried the prehistoric forests under the crust..
Coal
Coal is formed in nature by the carbonization of wood. Conversion of wood to coal under the influence of high temperature, high pressure and in the absence of air is termed carbonization...
