The Slow conversion of dead vegetation into coal is called carbonisation. Yes, it is the true statement as the process of carbonization is the slow process by which the dead plants buried deep under the earth surface have become coal. Coal is usually made from the remains of dead plants and animals known as fossil fuel.

Solution. Verified by Toppr. Dead remains of plants got buried under the earth millions of years ago. Due to intense heat and pressure inside the earth they got converted into coal. The process of conversion of dead remains of plants into coal is called carbonization.
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.
(a) The slow process of conversion of dead vegetation into coal is called carbonisation. (b) Coal and petroleum are formed from the dead remains of organisms and are known as fossil fuels. (c) The black thick liquid with an unpleasant smell is known as coal tar. (d) During the processing of coal to get a coke, coal tar and coal gas are also ...
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.
Solution. Verified by Toppr. Dead remains of plants got buried under the earth millions of years ago. Due to intense heat and pressure inside the earth they got converted into coal. The process of conversion of dead remains of plants into coal is called carbonization. Video Explanation.
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, which mainly contains carbon. The slow process of conversion of dead vegetation into coal is called carbonization. Question 4. Fill in the blanks.
The longestrunning study of its kind reviewed death records in the path of pollution from coalfired power plants. The numbers are staggering − but also falling fast as US coal plants close.

Where will be oil, gas and water present. 8) Constituents of petroleum are shown in figure below. Write one use of each constituent.
The conversion of dead vegetation into coal is called coalification. At various times in the geologic past, the Earth had dense forests in lowlying wetland areas. In these wetlands, the process of coalification began when dead plant matter was protected from biodegradation and oxidation, usually by mud or acidic water, and was converted into peat.
The temperature also increased 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.
