The picture depicts how the water cycle works. Overall there are several processes in the water cycle from steam form until it becomes water again.
To begin, the water in the surface runoff of the river is evaporated and the water from plants is transpirated. Both are transformed from liquid to steam which are located in the sky. Then, all of the steam, either from evaporation or transpiration, is condensed to become clouds. After that, cloud-formed, it can move and transport to many places.
Afterwards, when the clouds become gray, usually the sky would looks overcast at this moment, the water has fallen from the sky in the form of rain. Then, the process of precipitation began here. The water that has fallen is distributed by many rivers. At the same time, the water infiltrates into the ground, then in the underground, there is groundwater flow which streams water and it is taken by the plant. In the next step, water from the plant and river surface back to the first step.
