उत्तर
The water is evaporated from the surfaces of open oceans, seas, rivers, lakes, and from the surface of living organisms. The evaporated water gets condensed, precipitated, and form the water droplets. These water droplets are returned to the earth in the form of rain and snow or it may drop directly into the oceans. If it falls on land, it again flows back into the oceans through rivers and streams. The evaporation rainfall cycle repeats several times to get the average rainfall.
