Coal
Coal is a complex mixture of carbon, hydrogen and oxygen compounds. me nitrogen, sulphur and phosphorus compounds are also present in it. It is found in coal mines deep under the surface of earth. Story of formation : It is believed that millions of years ago, the ground below the forests was split open by natural forces such as earthquakes and volcanoes. The forests got buried under the surface of earth. Thus, the plants had no contact with oxygen. Successive layers of sediments sealed the buried plants. Over millions of year, these deposits were subjected to tremendous pressure and heat finally transformed them into coal.Carbonisation: The chemical process involved in the transformation of punt matter into coal is called the carbonisation of plant matter.

The carbon content of coal depends upon the variety of the coal. The higher the temperature and pressure of the Earth and the longer the coal has been hurried under the Earth, the more is the carbon content in it. So, the different varieties of coal are as follows (1) Peat (2) Lignite (3) Bituminous coal (4) Anthracite coal
