The given diagram demonstrates the hydrologic cycle which takes place above and below the surface of the Earth.
From an overall perspective, it is clear that, there are different stages of watercycle in which evapotranspiration takes place above the Earth and so much infiltration takes place under the soil.
To begin with, regularly flowing rivers get heated which helps in evaporation. After evaporating, the water particles goes to the sky and becomes clouds. Then , the clouds freezes. The condenseted clouds come back to the Earth in the form of rain. The water of the Earth runoff to mix with the source of water.
Then, lots of infiltration of rain water takes place under the soil. After the infiltration, high ground water goes to mix with the river water along with bedrock. Again, the process of evaporation takes place which helps to complete the natural water cycle. This process repeat again and again .
