How does the Water Cycle work?


I am learning to inform my audience through an explanation

By Vaiola

When drinking a bottle of water have you ever stopped and wondered where that water came from? Did you know water has been around us for millions of years all because of an amazing cycle called the water cycle. The term cycle means a set of steps or a series of steps which repeats over and over again. 97 percent of earth's water is salt water, 3 percent is freshwater and sadly only 1 percent of that water is actually drinkable.There are three main stages in the water cycle, evaporation, condensation and precipitation. If you were to remove any of these stages the water cycle would not be complete. Let’s start with evaporation

Evaporation is the first stage in the water cycle. Evaporation is a process by which a liquid changes into a gas called water vapour or aqueous vapour. Aqueous vapour is another name for water vapour. Evaporation happens when the sun heats up the water in lakes, rivers, ponds and oceans. Most of the water turns into water vapour. The water vapour then rises up into the sky it then forms into a cloud. Water vapour is invisible so you can not see it rising into the sky. An example of water vapour in our homes is a boiling kettle. When the kettle is boiled the steam from the kettle rises. Once you have noticed the steam has vanished it has turned into water vapour. Now to our next stop condensation.

Condensation is the second stage in the water cycle. Condensation is the change of which water vapour in the clouds cools down and turns back into tiny little droplets of water. An example of condensation is when you breath on a mirror. The warmth of your breath hits the cold mirror forming tiny little water droplets on the mirror. Some of the water vapour turns into liquid. Thousands of tiny water droplets form on the mirror. This is called condensation. Condensation is the opposite of evaporation. Once condensation is over precipitation takes its role. 

Precipitation is the final stage in the water cycle. Precipitation is a process by which water falls from a cloud. It can also appear not just as water but as hail, sleet and snow. Then the rain falls into rivers, lakes and oceans. After precipitation it starts all over again from evaporation back to precipitation.

These are the three stages of the water cycle. Evaporation is a process by which water changes into a gas called water vapour. Condensation is the change of which water vapour in the clouds turn back into little tiny droplets of water then last but not least precipitation. Precipitation is a process by which water falls from the clouds. What an interesting process this water has been through just to get in your drink bottle.
