Coal is formed by the bacterial action on dead vegetation. Over time, under high pressure and high temperature, dead plants got slowly converted to coal. Since coal mainly contains carbon this process of conversion is called carbonisation. Suggest Corrections 38 Similar questions Q. Describe how coal was formed. What is this process called ?
Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, 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.
Coal and petroleum are formed from the dead remains of living organisms that is why they are called fossils fuels. Question 5. Give two characteristics of coal. Answer: Coal is hard and is of black in colour. Question 6. Define destructive distillation. Name the residue formed by destructive distillation of 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. Coal, which is mainly carbon, on heating produces mainly carbon dioxide gas and a lot of heat energy.
Correct option is B) When they got buried deep in the soil, they were exposed to very high pressure and temperature. Under these conditions, these slowly got converted into coal. This process of the formation of coal from dead vegetation is called carbonization. Was this answer helpful?
Coal that is surfacemined is usually found in seams that range in size from 2 feet ( meter) to more than 100 feet (30 meters) thick. Some seams contain as much as 200,000 tons of coal in a single acre ( hectare). Normally, between 90 and 100 percent of this coal is recovered during surface mining operations.
When coal is heated strongly in the absence of air, a large number of organic and some inorganic compounds are formed. This process is called destructive distillation of coal. Two products of this process are coal tar and coal gas. Coal tar is a thick black liquid that is a byproduct of the destructive distillation of coal. It contains benzene ...
Answers (1) About 300 million year ago, Due to the natural calamities like flooding, storms and earthquake, the dense forests got buried under the soil. they were compressed, As more soil deposited over them. Under deep in the soil they were exposed to high pressure and high temperature, dead plants and animals slowly converted into coal.
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 Was this answer helpful? 0 0 Find All solutions for this book
Coal is formed by decomposition of living organisms which lived million years ago. Million years ago, plants and animals lived in a swampy forest. After the animals and plants died, other plants and animals grow instead of earlier organisms. The dead organisms form rot and form a layer of decaying things. After sometimes, water and light stop ...
The process of conversion of dead remains of plants into coal is called carbonization. Part 2: Uses of Coal : Coal is a typical conventional solid fuel that has been exploited as an important source of fuel by humankind for thousands of years.
Use this printable infographic to learn about the rock cycle. There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing ...
Bituminous Coal Bituminous coal is formed under more heat and pressure, and is 100 million to 300 million years old. ... Coal oil is made by heating cannel coal with a controlled amount of oxygen, a process called pyrolysis. Coal oil was used primarily as fuel for streetlights and other illumination. The widespread use of kerosene reduced the ...
Fossil fuels are nonrenewable sources of energy formed from the organic matter of plants and microorganisms that lived millions of years ago. The natural resources that typically fall under this category are coal, oil (petroleum), and natural gas. This energy (and CO 2) was originally captured via photosynthesis by living organisms such as plants, algae, and photosynthetic bacteria.
(a) The slow process of conversion of dead vegetation into coal is called ___. (b) Coal and petroleum are formed from the dead remains of organisms and are known as ___. (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. (e) The process of separating ...
Solution. Coal is formed by the bacterial action on dead vegetation. Over time, under high pressure and high temperature, dead plants got slowly converted to coal. Since coal mainly contains carbon this process of conversion is called carbonisation. Describe how coal was formed.
Q. Describe how coal is formed from dead vegetation. What is this process called? Ans. The process of coal formation is called carbonisation. The dead plants and vegetation due to temperature and high pressure over hundreds of years slowly turned into coal. This slow conversion of dead plants and forests into coal is called the process of ...
Ques. Describe how coal is formed from dead vegetation. What is this process called? [3 marks] Ans. About 300 million years ago the earth was covered with dense forest in low lying wetland areas. Because of numerous natural processes, like flooding and earthquakes, these forests got buried under layers of soil. When the soil was deposited layer ...
Describe how coal is formed from dead vegetation .What is this process called. The formation of coal begins in areas of swampy wetlands where groundwater is near or slightly above the topsoil. Because of this, the flora present produces organic matter quickly faster in fact than it can be decomposed. In these areas, layers of organic matter ...
There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...
Coal forms when swamp plants are buried, compacted and heated to become sedimentary rock in a process called coalification. "Very basically, coal is fossilized plants," James Hower, a...
Since coal was formed from the remains of the plants, it is called a fossil, which is mainly carbon, on heating produces mainly carbon dioxide gas and a lot of heat energy. Was this answer helpful? 0 0 Similar questions The process of conversion of dead vegetation into coal is termed as: Medium View solution > How is coal formed? Explain.
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.
Solution. Verified by Toppr. 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. Some iron and steel making and other industrial processes burn coal. The extraction and use of coal cause many premature deaths and many illnesses.
Most of the coal burned in US power plants is bituminous or subbituminous coal. A fifth type, called metallurgical (or "coking") coal, is used for steelmaking. All types of coal also contain sulfur, which, when burned, releases toxic air pollution. Sulfur content is determined by the conditions under which the coal is formed.
