Describe the water cycle with the help of an illustration.

Accepted Answer

The circulation of water from the earth’s surface to the atmosphere and back to the earth is called the water cycle. The water cycle is a continuous process. We know that water changes from one state to another on heating or cooling, due to change in its temperature. The sun plays a major role in bringing about changes in the state of water. When the sunlight falls on rivers, lakes, or oceans, it heats up the water and changes water into vapour by the process of evaporation. Leaves of the green plants also release water vapour into the air. This process is called transpiration. Water vapour in the air rises up and on cooling condenses to form clouds.

When the clouds become too heavy, the water falls back on the earth in the form of rain, hail, sleet, or snow. This is called precipitation. Most of the rainwater runs down the surface and becomes a part of the water bodies like rivers and streams, which eventually lead to the oceans. Water is again heated by the sunrays. It again evaporates, condenses, and falls back onto the earth.

This constant circulation of water in nature is called the water cycle.
