What is a Water Cycle ? Explained
WATER CYCLE Water Cycle : The cyclic movement of water from the atmosphere to the earth and back to the atmosphere through various processes is called Water Cycle. The steps involved in the water cycle are : Evaporation, Transpiration, Condensation, Percipitation and surface run off. Water is present on the earth in rivers, ponds, oceans, lakes and soil. Some water is also present in the ground. Heat from the sun evaporates from rivers, lakes, ponds, oceans and soil to form WATER VAPOUR (gas). This process is called EVAPORATION . The water vapour(gas) goes into the air. The plants and trees absorb water from the soil through their roots. The plant and trees lose water as water vapour by the process of TRASPIRATION. The water vapour goes into the air. The air containing the water vapour is heated by the sun. hot air, being lighter, rises high in the sky. So, when the air containing the water vapour rises to high altitude, the water v...
