The slow process of conversion of dead vegetation into coal is known as carbonization. Coal is formed from the remains of vegetation; therefore, it is also known as fossil fuel. When coal burns, it produces mainly carbon dioxide gas. When coal is processed in industry, it produces some useful products such as coke, coal tar, and coal gas.

The slow process of conversion of dead vegetation into coal is called . 3. Coal, and natural gas are fossil fuels. 4. The resources that are present in unlimited quantity in nature and are not likely to be exhausted are called . ... Reason Formation of fossil fuel is a very slow process. 5. Assertion The layer of petroleum and ...
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.
Coal is fossil fuel or fuel that comes from the remains of prehistoric plants or animals. The formation of coal occurs over millions of years via a process known as carbonation. In this process, dead vegetation is converted into carbonrich coal under very high temperature and pressure. Table of Contents. Formation of Coal; Recommended Videos
Refining is the process of purifying a substance and recycling is the process of converting waste into useful substances. Thus, options A, B, and C are incorrect. Coal is mainly composed of carbon. Thus, the conversion of dead vegetation into coal is termed carbonization. So option D is correct.
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.
Due to high pressure and temperature and the absence of air, the wood of the buried forest plants and trees slowly got converted into coal. The slow process by which the dead plants buried under the Earth have become coal is called as carbonisation. Since coal was formed from the remains of the plants, it is called a fossil fuel.
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.
(a) Fossil fuels are coal, petroleum, and natural gas. (b) Coal contains mainly carbon. (c) The slow process of conversion of dead vegetation into coal is called carbonisation. (d) The process of separation of different constituents from petroleum is refining. (e) The least polluting fuel for vehicle is CNG (f) The burning of fossil fuel causes ...
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.
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.
Best Answer. carbonisation Solution: Plants contain mainly carbon, which gets converted into coal. Hence, the slow process of conversion of dead vegetation into coal is called carbonisation. 3.
