describe how coal was formed
Answers
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 causes many premature deaths and much illness.
Answer:
The process of formation of coal is as follows:
About 300 million years ago, the earth had dense forests in low lying wetland areas.
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.
This process is known as Carbonisation
