THE WATER CYCLE INTRODUCTION T he water cycle is a process where water goes through key stages . E.g evaporation , condensation , precipitation , runoff and Groundwater . There is no start or end to this process , this water has been recycled from around 4 billion years ago . EVAPORATION Evaporation is where the sun heats up the water and turns it into vapour . This process is an invisible process you cannot see this happening , usually . Do you know that plants and trees can also lose water into the atmosphere , through their leaves this process is known as Transpiration . Two of the next steps are Condensation and Precipitation . CONDENSATION Condensation is where vapour rises into the air , it cools and turns back into a liquid , forming clouds . The currents high up in the air move the clouds from place to place all around the world . The next step is precipitation . PRECIPITATION W hen too much water has condensed it becomes too ...
