Petroleum Conservation Research Association. Question 8. It is a non-crystalline form of carbon. ... some plants grew into giant ferns and mosses. As more soil deposited over them, they were compressed. Peat is a fossil fuel that is the first stage in the long process of plant material turning into coal. Under high pressure and high temperature, dead plants got slowly converted to coal. Coke is the almost pure form of carbon. C + O 2 → CO 2 Coal was used as fuel in steam engines. With the passage of time, as more and more soil got deposited on them, the buried plants were compressed. Coal: A fossil fuel, that forms by the decay of vegetation, which existed millions of years ago. (c) 14. These plants got buried into the bottom of the soil and deposited as fossil due to heat and pressure. Carbonization: The slow process of conversion of dead vegetations into coal is called carbonization. The buried plants underwent carbonization and changed into coal. The temperature also rose as they sank deeper and deeper. 13. are exhaustible natural resources. COAL • As coal contains mainly carbon, the slow process of conversion of dead vegetation into coal is called carbonization. Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Ancient bog plants, mostly sphagnum moss, are the fossils in peat. Carbonisation is a. Peatlands Thick, spongy layers of histosol eventually form peat. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. 8. 14. Under high pressure and temperature, slowly plants got converted into coal. The slow process of conversion of dead vegetation into coal is called _____ Ans:Carbonization. Since it was formed from the remains of vegetation, coal is also called a fossil fuel. • Since it was formed from the remains of vegetation, coal is also called a fossil fuel. Slow conversion of dead vegetation Into coal b. Deposition of soil c. falling of trees d. None of these Ans . Under high pressure and high temperature, dead plants got slowly converted to coal. 15.
