The burning of fossil fuels refers to the burning of oil, natural gas, and coal to generate energy. We use this energy to generate electricity, and to power transportation (for example, cars and planes) and industrial processes. Ever since the invention of the first coalfired steam engines of the 1700s, our burning of fossil fuels has steadily ...

Natural gas is a fossil fuel energy source. Natural gas contains many different compounds. The largest component of natural gas is methane, a compound with one carbon atom and four hydrogen atoms (CH 4 ). Natural gas also contains smaller amounts of natural gas liquids (NGLs, which are also hydrocarbon gas liquids ), and nonhydrocarbon gases ...

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 ...

Coal is formed when dead plant matter submerged in swamp environments is subjected to the geological forces of heat and pressure over hundreds of millions of years. Over time, the plant matter transforms from moist, lowcarbon peat, to coal, an energy and carbondense black or brownishblack sedimentary rock.

Kotanigawa et al. (1997) examined an active site of coal liquefaction, where sulphate species formed on the surface of the ironbased catalysts during the liquefaction process. Thorpe found that FeS 2 in coal was oxidized with oxygen. At 582 K, the surface of FeS 2 was oxidized to FeSO 4. FeSO 4 was formed by oxidation of FeSO 4 and FeS 2 at 677 K.

Coal Plant Matter, Carbonization, Sedimentary Rocks: It is generally accepted that most coals formed from plants that grew in and adjacent to swamps in warm, humid regions. Material derived from these plants accumulated in lowlying areas that remained wet most of the time and was converted to peat through the activity of microorganisms.

Coal is formed through a process called coalification, which involves the transformation of plant materials over millions of years. As plants and organic matter accumulate and are buried in swampy environments, they undergo physical and chemical changes due to heat and pressure, eventually resulting in the formation of coal. 10

Solution Formation of coal : Coal is formed from the remains of the plants that existed in swampy forests some 200—300 million years ago. These plants got buried under the Earth due to some geological changes. As more and more materials piled on top of them, they were compressed. Coal is extracted from mines.

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.

When the vegetation died, it could not fully decompose due to oxygenpoor conditions. Instead, it formed peat (a brown substance high in organic content). The peat was buried and formed coal after millions of years of high pressure and temperature. The pressure was from the weight of sediments as well as from continental collisions.

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.
