How does the water that evaporate from earth reach back to earth itself explain?

Evaporation is part of the water cycle. Water is evaporated by the sun from rivers, lakes, the sea and some is evaporated from the land. This water vapour rises into the atmosphere when it is cooled and condenses to form clouds when the water vapour is cooled further rain or another form of precipitation is formed. The rain hail snow etc falls to the ground and so the water has completed the cycle.
