What is Water Cycle?

The water cycle is a continuous cycle where water evaporates, moves into the air and becomes part of a cloud, falls down to earth as rainfall, and then evaporates again. This process repeats again and again and water keeps changing its state from a solid to a liquid to a gas, over and over again. 1. Water from sea, ocean and lakes evaporates into air because of Sun’s heat energy. Evaporation is the change of state of water from a liquid to water vapor (a gas). 2. Plants also lose water to the air through the process called transpiration. Transpiration is evaporation of liquid water from plants and trees into the atmosphere. Nearly all (99%) of all water that enters the roots transpires into the atmosphere. 3. Even ice and snow on earth’s surface changes into water vapor (a gas) without moving through the liquid phase by the process called sublimation. 4. The water vapour rises up in the atmosphere where temperature is cooler. This cools the water vapour and it condenses to form tiny droplets of water. These tiny droplets of water combine together to form cloud. 6. The droplets become heavier in air and falls to the earth as rain or snowfall. This is called precipitation. Most precipitation falls as rain but includes snow, sleet, drizzle, and hail. 7. Rain water that falls on the earth’s surface percolation through the soil going deep into the groundwater, seep into the oceans, river, falls on the mountain and get frozen. 10. The water again evaporates and forms the water cycle. For feedback: pls write to smartscholar.edu@gmail.com
