When these died, they too got covered. Sometimes earthquake and volcanoes buried entire forests deep down in the earth. The high temperature and high pressure inside the earth slowly converted the buried vegetation into coal. A coal contains mainly carbon. Thus, this slow process of conversion of wood into coal is called carbonization.
The slow process of conversion of dead vegetation into coal is called as carbonisation. Since coal was formed from the remains of the plants, it is called a fossil formation of coaloccurs over millions of years. In thisprocess, dead vegetation is converted into carbonrich coal under very high temperature and pressure.

Under high pressure and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Since most of these substances were organic in nature, their decomposition led to large reserves of coal that we find today.

(c) The black thick liquid with ___ smell is known as coal tar (d) During the processing of coal to get coke, coal tar and ___ are also obtained.
The temperature also rose as they sank deeper and deeper. Under high pressure and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Since it was formed from the remains of vegetation, coal is also called a fossil fuel.
As more soil deposited over them, they were compressed. The temperature also rose as they sank deeper and deeper. Under high pressure and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. Question 4: Fill in the blanks.
Origin and occurrence of coal. Coals are obtained by natural 300 million years ago the earth had dense forests in low lying wetland to natural processes,like flooding, these forests buried under soil deposited over them they were compressed.
As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation. → Coal is one of the fuels used to cook food. It is also used in thermal power plants to produce electricity. and also used as a fuel in various industries.
Solution. The correct option is B carbonisation. The forests got buried under the soil. The temperature rose as they got deeper and deeper. Under high pressure and high temperature, dead plants got slowly converted to coal. As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonisation.
