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.
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.
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
The three fossil fuels are oil, natural gas, and coal. They are hydrocarbons formed from deeplyburied, dead organic material subject to high temperature and pressure for hundreds of millions of years and are a depletable, nonrenewable energy resource. Fossil fuel combustion (converting chemical energy into heat) powered the Industrial ...
25. Describe how coal was formed. What is this process called? Answer Dense forests got buried under the soil due to natural processes, millions of years ago. More and more soil got deposited over them and they got compressed more. This led them to get exposed to very high temperature and pressure.

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.
The formation of coal occurs over millions of years via a process known as carbonation. In this process, dead vegetation is converted into coal which is found to be carbonrich under very high temperature and pressure. Coal is also called as black gold. Now let's discuss about how coal is formed. The formation of coal occurs over ...
This process is called carbonization. So, carbonization can be defined as the slow process in which the dead plants and trees under the surface of the earth in high pressure and temperature form coal. It is called fossil fuels because it is formed by the dead remains of plants. So, when coal is heated it forms carbon dioxide and heat energy.

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.
Coal is pulled from the Earth by way of mining. Reserves of coal, often called coal seams or beds, can measure some 30 m (90 ft) deep and stretch 1,500 km (920 miles). The Earth's largest coal reserves are the United States, China, Russia, Australia, and India. Overall, coal makes up approximately onethird of the energy sources used around ...
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...
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.
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.
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.
Question 3 Describe how coal is formed from dead vegetation. What is this process called? Answer Coal was formed by the decomposition of large land plants and trees buried under the earth 300 million years ago. About 300 million years ago,the earth had dense forests in lowlying wet land areas. Due to natural processes like earthquake ...
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. Suggest Corrections 21 Similar questions Q. Question 3
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 ...
This high pressure and temperature in the absence of air lead to conversion of dead plants and animals into coal. Coal contains mainly carbon. Hence, this process of slow process of conversion of dead vegetation into coal is called carbonization. Since it was formed from the remains of vegetation, coal is also called a fossil fuel.
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.
This process of conversion of dead plants and trees into Carbon is called Carbonization Steps of Coal Formation Millions of years ago, there were dense forests on earth in low lying areas ...
