Coal is a combustible black or brownishblack sedimentary rock with a high amount of carbon and hydrocarbons. Coal is classified as a nonrenewable energy source because it takes millions of years to form. Coal contains the energy stored by plants that lived hundreds of millions of years ago in swampy forests. Layers of dirt and rock covered the ...

The formation of coal takes millions of years, which is why it is an exhaustible and nonrenewable natural resource. It was formed around 300 million years ago when the earth was covered with swampy forests. When plants in these forests mainly trees, mosses, ferns, and reeds died, they fell into the swamps. And this process is called ...

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.

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.

Fossil fuels are made from decomposing plants and animals. These fuels are found in Earth's crust and contain carbon and hydrogen, which can be burned for energy. Coal, oil, and natural gas are examples of fossil fuels. Coal is a material usually found in sedimentary rock deposits where rock and dead plant and animal matter are piled up in layers. More than 50 percent of a piece of coal's ...

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.

coal produced in the United States is subbituminous. Wyoming is the leading source of subbituminous coal. Bituminous coal contains 4586 percent carbon, and has two to three times the heating value of lignite. Bituminous coal was formed under high heat and pressure. Bituminous coal in the United States is between 100 to 300 million years old.

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.
