2.2.1. Temperature

Temperature goes on increasing with the increase in depth inside the earth. This is clearly proved while going down a mine or deep wells. The volcanic eruptions or hot water springs also confirm this fact that temperature increasing towards the interior of the earth. On an average, there is a rise of 1oC temperature for every 32 meters of depth. This rapid increase in temperature continues to great depth there after the temperature increases slowly.
