Question

how coal is formed what is the uses of coal

Answer 1

As plants died 300 million years ago, their remains sank to the swampy areas, making layers and layers of plants and eventually formed into peat known as coal.
Coal is used as fuel in industries. Its main uses lies in generating electricity, steel production and cement manufacturing etc..

Answer 2

Coal is used primarily as an energy source, either for heat or electricity. It was once heavily used to heat homes and power locomotives and factories. Bituminous coal is also used to produce coke for making steel and other industrial process heating. Coal gasification and coal liquefaction (coal-to-liquids) are also possible uses of coal for producing synthetic fuel. Approximately 4% of the coal mined in the United States is exported, and most of the exported coal is used for making steel. and. formation Living plants store solar energy through photosynthesis. When plants die, they decay and release the stored energy into the atmosphere. But, over 300 million years ago, even before the dinosaurs, many plants died in swamps. These plants were buried under water and dirt due to which the decaying process is interrupted. This prevented the release of the stored solar energy from the pants into the atmosphere. Under high temperature and pressure, many physical and chemical changes occurred in these dead plants with locked energy; thus, resulted in the formation of a large amount of coal
