The water cycle

                                    The Water cycle:
The water cycle is a repetitive process, that contains four stages. Evaporation, Condensation, Precipitation and Runoff. Furthermore, water is recycled throughout this never ending process. In addition, the process the water goes through is between land, sea and atmosphere. Moreover, throughout this process the water changes state between a liquid,soil and gas. The first step in the water cycle is Evaporation.


The unofficial first step in the water cycle is Evaporation; evaporation is when the sun heats up water in the ocean, river, lakes, puddles etc, it then evaporates into a gas. In addition, snow and ice can actually turn into water vapor without actually melting first, Furthermore This is called sublimation. Another point is that, evaporation is an invisible process and can not be seen. On really hot days the process of evaporation is greater and water vapor is formed quicker. Moreover, after evaporation has occurred ; the next step in the water cycle is condensation and precipitation.


The second and third step in the water cycle is Condensation and precipitation. Condensation is when the gas forms clouds. Furthermore, when the clouds get too heavy precipitation occurs ; Precipitation is when rain, hail, sleet or snow falls. For an example, condensation is formed because of temperature changes, Furthermore, warmer air contains more water vapor. Another fact about condensation is that it is the opposite of evaporation because it changes state and transforms from a gas into liquid water. In addition, precipitation can only be a type of rain so it can’t be something like lightning or thunder because it can’t melt. After condensation and precipitation have happened the final stage in the water cycle is runoff.


After evaporation, condensation and precipitation ; the final step in the water cycle is runoff. Runoff is when the water falls to the ground ( precipitation) The water finds it’s way on the earth’s surface into puddles, rivers, streams etc. It then restarts the cycle and evaporates. Furthermore, some of precipitation falls directly into rivers, puddles, streams, it will then evaporation. In addition in cold areas snow or hail can possibly fall. If   it does get hotter it may melt and turn into a liquid water and runoff into puddles etc. Another point is that, when water falls on vegetation it is possible that it will evaporation from leaves/ nature back into water vapor.

Overall there's four-steps in the water cycle Evaporation, Condensation, Precipitation and Runoff. This cycle is never ending and the water is recycled throughout this process ; Furthermore, in this cycle the water changes state. Overall if a step was skipped or missed in the water cycle it wouldn’t work properly ,Furthermore The water cycle is important because water is needed for a lot of things like Irrigation, Domestic Use, Industry and a lot of other things.
