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.

Formation of Coal (Process) Coal is composed of carbon, hydrogen, oxygen, nitrogen, sulphur, moisture, and incombustible mineral matter (, ash). Fluorinated gases are not formed by coal combustion. Coals are formed from the accumulation of vegetable debris in specialized environments. Obtaining coal from the mines is a difficult job.

Coal and Petroleum. Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.

Law of Conservation of Mass. The law of conservation of mass was created in 1789 by a French chemist, Antoine Lavoisier. The law of conservation of mass states that matter cannot be created or destroyed in a chemical reaction. For example, when wood burns, the mass of the soot, ashes, and gases equals the original mass of the charcoal and the oxygen when it first reacted.

In a process called photosynthesis, these organisms convert light energy from the sun into chemical energy stored in sugars. However, the light energy doesn't produce the atoms that make up those sugars—that would break the Law of Conservation of Mass —it simply provides energy for a chemical change to occur.

71,757 How is Coal Formed? 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.

The slow process of conservation of dead vegetation into coal is called Carbonisation. Since it was formed from the remain of vegetation, coal is also called a fossil fuel. When heated in air, coal burns and produces mainly carbon dioxide gas. Coal is processed in industry to get some useful products such as coke, coal tar, coal gas.

Coal is the most abundantly found fossil fuel and is used as a domestic fuel, in industries such as iron and steel, steam engines and to generate electricity. Electricity from coal is called thermal power. The coal which we are using today was formed millions of years ago when giant ferns and swamps got buried under the layers of earth.

Coal is formed from the remains of plants, by a process called coalification. The whole process starts with the remains of dead plants, which must be buried in an oxygenpoor or oxygenfree environment, to avoid complete decomposition. Usually, these are swamptype environments. The coalification process takes place over millions of years.

Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.

It is the coal with the lowest carbon content. The carbon content is only about 6070 %. It is formed during the younger stages of coal formation and thus has a lower carbon content. Due to the less amount of carbon, it is not fully black in colour and is somewhat brown. Lignite is used in electricity generation and in fertilizer production.
