The diagram below shows the water cycle, which is the continuous movement of water on, above and below the surface of the Earth. Summarise the information by selecting and reporting the main features and make comparisons where relevant.
The diagram illustrates the continuous movement of water on, above and below the Earth’s surface, popularly known as the “water cycle”.
It is pretty evident that there are mainly three stages in the process, the first is the evaporation of water, the second stage is cloud formation, and the last stage is the fall of water on the surface of Earth.
In the first stage, about 80% of water vapour in the air is from the ocean. Heat affects the condensing water vapour to form clouds, then after the process called ‘precipitation’, the waterfalls in the form of rain or snow.
The final stage of the cycle is when the water takes various paths. Some water comes from lakes, whereas some of it may travel to the ocean as ground. Otherwise, some water passes through impervious layers and reaches the ocean. However, the process of saltwater intrusion takes place before the water enters the ocean. So, completing all steps, the cycle begins again.
