The diagram below shows the water cycle, which is the continuous movement of water on, above and below the surface of the Earth.
The given arrow diagram describes the water cycle above and below the earth.
The chart illustrate the water cycle as a continuous process in three stages such as evaporation of water from the sea, rain fall, and back flow of water to the sea.
In the first stage, due to the heat from the sunrays sea water evaporates which contributes 80% the total water vapor in the air, eventually forming clouds, containing water vapor.
This water results in rain fall, water vapors formed as water drops fall in the earth surface. It is stored in the lakes, form snow and the third part flow back to the sea.
In the third step, the surface water after a rainfall go deep into the earth and became ground water. It moves to the impervious layer. The water penetrate from the surface of the earth also came to the impervious layer. This water finally fall in to the sea and the process continuous.
In short, the water cycle is a continuous process which helps to maintain the needs of water in the earth.
