The provided picture illustrates the cycle of water situated on different positions compared to the surface of the earth.
Overall, it is evident that there are a total of three main stages in the process shown. Additionally, it is also noticeable that this process is cyclical, initiating from the evaporation of water from the ocean to the running back of water to the ocean eventually.
Looking at the diagram in more detail, about 80% of vapor water is attributed to the ocean. After the evaporation of the condensed vapor water, the clouds are formed. Water from the precipitation will then become rain or snow. Following that, these water will fall into lakes or runoff down the surface of the earth.
In the third stage of the process, the water will flow under the earth, which will become underground water, continuing to go more deeply until reaching the imperious layer. Eventually, these water will flow back to the ocean after the salt water intrusion.
