The picture illustrates how water moves from the ocean to the air and then to the land during the natural process known as the water cycle.
The diagram depicts three main stages: evaporation, precipitation, and collection. Ocean water evaporates, returns to Earth as rain or snow, and eventually makes its way back to the oceans.
Starting with the evaporation stage, we see that 80% of the water vapor in the atmosphere originates from the oceans. Heat from the sun causes water to evaporate, and this water vapor condenses to form clouds. The second stage, labeled precipitation on the diagram, shows water falling back to the surface as rain or snow.
In the third stage of the cycle, rainwater can take different paths. Some of it may flow into lakes or return to the oceans through surface runoff. Alternatively, rainwater can filter into the ground, reaching the impervious layer of the earth. The process of saltwater intrusion occurs just before groundwater flows back into the oceans, completing the cycle.
