Explain the formation of coal.
Formation of Coal:
(1)The formation of coal took millions of years.
(2)Coal was formed by the bacterial decomposition of ancient vegetable matter buried under successive layers of the earth.
(3)Under the action of high temperature and pressure, and in the absence of air, the decayed vegetable matter gets converted into coal.
(4)With each successive layer of coal formed, the amount of carbon present in the deposit increases and the level of impurities decreases.
(5)This process is known as carbonization and the most active episode of carbonization took place in the carboniferous era,i.e.270 million years ago.
(6)Carbonization is the process of slow conversion of vegetable matter into carbon-rich substances such as coal.
