The diagram illustrates how water cycle occurs in the given stages.
Overall, the water cycle is the sustainable process of evaporating and forming cloud which then returns the water to the land and sea in the form of rain.
Initially, heat from the sun causes water in the ocean to evaporate, producing water vapour, after which the vapour condenses and begins to form in a cloud.
The next steps involve returning it back to a liquid state. While the precipitation of the cloud is happening, the rainwater flows into lakes, sea and on the earth. The rainwater turns to snow at the peak of the mountains. However, in the lower regions, some of it flows through the surface of the land into the ocean, while some is absorbed by the soil and becomes groundwater. Finally, in the salt water intrusion step of the process, the return freshwater mixes with the salty water of the sea or ocean.
