Water Cycle



How the Water Cycle Works?
I am learning to inform my audience through an explanation.

Did you know when you drink a glass of water you are probably drinking water that the first cave people also drank? The Earth has been recycling water for years! This process is called the water cycle. The water cycle is so simple anyone could understand it. Three quarters of the earth is covered in water, however only three percent is freshwater and even smaller is the actual drinkable water at one percent. There are three stages in the water cycle evaporation, precipitation and condensation. Each stage plays an important role in the water cycle.




Evaporation is the start of the water cycle. Evaporation is a process where water turns into water vapor. For example after a rainy day the rain leaves puddles on the Earth's surface. After the rain and an hour or so the water is gone that is because the sun has evaporated the water from the puddle. It doesn't have to be a sunny day for water to evaporate because the sun is always shining even when it is a stormy day, and supplying heat to the earth. From evaporation it leads into condensation.




Have you ever seen water on a window on a cold day? That is called condensation.

Condensation is when water vapor collect together together and is cooled down. Once it has collected together it then forms a liquid together as it connects together. The water vapor in the water cycle rises up into the atmosphere and it collects together and forms a cloud. Once the water vapor cools and collects together it gets darker and darker until it is ready to fall. This leads us into precipitation



Precipitation is when a cloud gets really full then the water falls from the cloud then it rains. Did you know when it rains you could be seeing water from the other side of the world? This is because the clouds evaporate water from the lakes, rivers and oceans from around the world and then the clouds come to where you live then it rains. Clouds move all around the world. When the clouds get heavy enough they water falls back down to earth as precipitation. This can be in the form of rain, hail, sleet or snow depending on the temperature in the atmosphere.




In conclusion there are three stages in the water cycle evaporation, condensation and precipitation, each stage plays evaporation evaporates the water condensation turns the water into a gas and precipitation makes it rain important role in the water cycle. Water is a very important resource in the world. If there was not a water cycle we would not be here today.
