The sea water evaporates due to extreme heat of the sun. The evaporated water vapour is taken as long distances by the wind and is becomes cloud due to condensation of water vapour. the cloud contains water droplets along with frozen water at high altitude which acts as big piece and collides with the Himalayas. due to the collision, water is the form of ice begins to shake and melts so that begins to fall down in the form of rain. The rain water gets soaked into the soil and comes out as springs and rivers. The deposited water underground may be obtained from wells.
