Describe In Scientific Terms The Circulation Of Water In The Environment?

The term circulation of water is used to refer to the process by which the water flows in a body of water (such as an ocean, a river, a sea, a lake, a pond, a stream, etc.) due to such factors as the wind and other forces of nature. The circulation of water also takes place due to the variations in the density or due to the changes in the temperature.

The phrase water circulation is used to define such situations which are not specifically covered by narrower terms. It is a term which has a broad scope. When scientists talk about the circulation of water in a broader context, they usually mean the circulation of water in the oceans. Oceans are the largest bodies of water and cover approximately three-quarters of the Earth's surface.

The circulation of water in the environment is scientifically called the water cycle.
Our earth is made up of 1/3rd water and 2/3rd land area. Hence, water is a very important part of our ecosystem and also our lives. Presence of water is very important for supporting life in our planet. It is also very important that water circulates in our environment to support life and give us fresh clean water for our everyday use.

The water cycle comprises of a few processes. These processes are evaporation which also includes the process of transpiration from plants, the process of condensation, the process of precipitation, and process of accumulation. After the process of accumulation, the water again starts a new cycle.

Evaporation happens from any surface of water such as rivers, lakes, ponds, even the pail of water in your kitchen. The evaporated water rises up to the sky and reaches the temperature where they condense into tiny droplets of water which we call clouds. The tiny droplets coalesce together to form drops which come down subsequently as rain. This rain is again collected in ponds, rivers, streams, tanks and the cycle starts again.
