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 ...

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.

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.

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 ...

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.

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 ...

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 ...

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 ...
