It evaporates and water vapour rises into atmosphere making it humid.

I. When the vapour rises higher and mixes with the cold air, it turns into small water droplets and forms clouds. In other words, water vapour condenses out of

the air. When the little droplets run into each other because of the wind, larger drops grow, and start falling on the ground because the air can't hold them any more. When clouds rise higher, the water in them freezes and turns into little balls of ice, which may fall like hail or snow on the ground some time later. The water in the clouds can freeze and turn into ice crystals and fall like snowflakes on the ground.
