Question

How do coal beds form?

Answer 1

Hint: Coal formation takes a considerable period to develop. Coal beds composed of plant remains. When forested swamps die, they drop below the water and start forming coal.
However, for coal formation, more than a significant vegetation growth is required.

Complete answer:
First, one should know about fossil fuels to answer this question. Fossil fuel is produced through natural processes like buried dead organisms' anaerobic decomposition, comprising organic molecules resulting from ancient photosynthesis that emit energy during combustion.
Coal, natural gas, petroleum, oil shale, bitumen, heavy oils, and tar sands are fossil fuels. Fossil fuels are used to warm our homes, drive our automobiles, power industry, and supply us with electricity.
As old peat forests are buried and collapsed, coal is produced. Heat and pressure allow the buried organic matter to form coal over thousands of years.
If the temperature increases, it releases carbon dioxide, nitrogen, oxygen which increases the proportion of carbon. What remains, finally, is a layer of coal that is thinner than the layer of peat from which the foal was made.

Note: The first phase in the coal formation is peat. Vegetable matter is normally oxidized into carbon dioxide and water. However, oxygen is not seen if plant matter accumulates underwater and so only minimal decomposition results.
This incomplete degradation contributes to an organic material called peat. Peat is a soft, fibrous, spongy material of which it is easy to recognize plant remains.
A significant volume of water is contained and should be drained before use. It is, however, rarely used as a heat source. With a long flame and substantial smoke, pete burns.
