The diagram illustrates the natural cycle of water in an evapotranspiration process. Generally, the whole cycle shows the way how water transforms through various steps, from evaporation, condensation, infiltration to runoff and flow back to the water sources.
Firstly, water from the flowing stream will be evaporated by the heat from the sun. Consequently, water will change from liquid form to air form, and through condensation, air steam will transform into a denser form, which is known as clouds. When the clouds get heavier, it will pour water back to the ground. Water through this process will go back to its original liquid form by a process called rainfall.
After rainfall, water will go back to the flowing stream through two distinctive ways. The first way is the process that water flowing through runoffs will go back to the water sources, such as streams or rivers. The second way, on the other side, is the way water infiltrates into the ground and forms a series of high groundwater streams. Water through this way flows on the streamlines above the bedrock layer, which will soon join with the constantly flowing stream.
