1) In-situ theory-According to this theory, the coal seams are observed where once forest grew. As the land was sinking slowly, the accumulated vegetation matters went under water slowly and did not decompose and destroyed. In the course of time, the rate of sinking of land was increased and coal forest was submerged under water. Again, land
