Explain how the water cycle removes pollutants from earth’s water

During the water cycle, the water on the earth's surface gets evaporated leaving the impurities behind and enters into the atmosphere as water vapor. Thus, the water cycle removes pollutants from earth’s water.

Explanation:

Water cycle is the continuous movement of water on the earth's surface and the atmosphere. Some of the water from the oceans, lakes, rivers etc gets evaporated by sunlight and enters into the atmosphere as water vapor. Also from the processes like sublimation (ice and snow) and evapotranspiration (plants), water vapor reaches the atmosphere. This vapor is then condensed into clouds and later falls back from the sky on to the earth's surface as precipitations like rain, snow etc. During the evaporation, the pollutants (impurities) in the water sources are left behind. Thus, the water cycle removes pollutants from earth’s water.
