Uses of Coal. It is mainly used to generate heat and electricity. It is used in s and in industries to accomplish various tasks. It is the cheapest source of power fuel. The iron and steel industry depends heavily on fossil fuel for energy. It is also used to produce useful products such as coke, tar, and coal gas.

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.

Formation of anthracite coal: Anthracite coal, also known as hard coal, is formed when bituminous coal undergoes additional heat and pressure. This process increases the carbon content and reduces the volatile components, resulting in a hard, shiny black coal with a high carbon content. It's important to note that the formation of coal is a ...

However, petroleum, like coal and natural gas, is a nonrenewable source of energy. It took millions of years for it to form, and when it is extracted and consumed, there is no way for us to replace it. Oil supplies will run out. Eventually, the world will reach " peak oil," or its highest production level. Some experts predict peak oil ...

Explanation: When there is continuous elimination of H 2 gas, it creates an anaerobic condition due to which there is loss O 2 which creates anthracite directly. For aerobic decay, under sedimentary rocks lignite and bituminous coal are formed under different conditions.

Earth Science Coal is a fossil fuel that has been used for several hundred years. Most people have heard of coal and know that the Earths coal supplies are limited but they may not know how coal was formed. There are some mistaken beliefs that coal comes from the remains of long extinct dinosaurs but this is not true.

Due to natural processes like flooding, these forests got buried under the soil. As more soil was deposited, they were compressed. With an increase in depth, the temperature also rises. Under high pressure and high temperature, dead plants got slowly converted into coal. The process of coal formation is very slow and might take millions of years.

The coal formation process involves the burial of peat, which is made of partly decayed plant materials, deep underground. The heat and pressure of burial alters the texture and increases the carbon content of the peat, which transforms it into coal, a type of sedimentary rock. This process takes millions of years. Types, or "ranks," of coal are determined by carbon content. There are four ...

Coal is the most abundant fossil fuel on Earth. Its predominant use has always been for producing heat energy. It was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries, and the industrial growth of that era in turn supported the largescale exploitation of coal deposits. Since the mid20th century, coal has yielded its place to petroleum and natural ...

There are two main phases in coal formation: peatification and coalification. Bacterial activity is the main process that creates the peat during peatification. Increasing temperature and pressure from burial are the main factors in coalification. [2] To form coal, the following steps are followed (Figure 2 illustrates these steps): [5] [6]
