<u>Explanation:</u>
The cycling of water which starts at lakes, ponds, rivers, and seas by evaporation of water due to sun rays, leading to cooling of water vapours at upper layers of atmosphere forming clouds, and those clouds shedding the water on landforms as rain, hail, snow etc is called water cycle. This water cycle is important for the vegetation as well as survival of any form of life in the interior of the landforms.
