Water Cycle
The water cycle is the continuous exchange of different forms of water in nature. It has also named as hydrological cycle. Water changes its shape through the process of evaporation, condensation and precipitation. Water is so important to our life that we call it 'our life'. We use water massively in our daily life. Hence, it never run down from our earth because a cycling system acts upon it. Most of the earth's surface is covered with water. From water bodies like oceans, rivers, lakes, ponds, streams, water evaporates because of the heat of the Sun. In the presence of the sunlight water turns into vapour. Then the vapour rises to the sky. There it gets heavier enclosing each other. After that, it condenses with the dust and makes clouds. When these clouds can not floating in the sky, it descends to earth by gravity. Then it again fills the water bodies of the earth.
