How Does the Water Cycle work

I am learning to inform my audience with an explanation writing
Have you ever drank a glass of water and thought to yourself where did this water come from? It could have been water that a dinosaur swam in or that a caveman bathed in? These are all possible answers because of the water cycle. All the water on earth is all the water that has ever been on earth ! Three quarters of the earth is covered in water. 97 percent of the earth's water is salt water, leaving only three percent to be fresh water. However only one percent of freshwater is drinkable. Water is an amazing substance that all animals and most plants require for survival. The water cycle is so simple yet so complex that even the best scientists are still investigating the water cycle and how it works. A cycle is a series of steps that repeats itself over and over. There are three main stages of the water cycle evaporation, condensation and precipitation. Let's take a look at one of the stages, evaporation.
Evaporation is one of the stages in the water cycle. Evaporation is when water is heated by the sun, it turns into a gas called water vapour. Water vapour can be created in room temperature, this goes to show that water can be in the air at any time any where, sometimes there is a lot of water in the air and sometimes there is not so much. Once evaporation has happened the stage called condensation can occur.
The condensation stage happens when all of the water vapour that has risen up through evaporation. It gets up really high, it then begins cools down. When it is cooling down the water vapour turns to water droplets. The wind blows these water droplets together and they merge gradually getting heavier. Once it gets heavier it becomes visible and that's when you start to see a cloud. The final stage of the water cycle is precipitation.
Precipitation is the most straightforward stage of the water cycle. The clouds usually get darker and cooler. Precipitation is the process of when water is released from clouds in the form of rain, sleet, snow, or hail. This is the way that the water cycle takes the water from the clouds and returns it back to lakes, oceans and seas. Most precipitation falls as rain because it is normally not cold enough to produce snow, sleet or hail and that's how precipitation happens.
In conclusion the water cycle is an amazing cycle and all life on earth needs it to survive. Evaporation is when water heats up and then it goes up. Condensation is when all of the water vapour cools down forming a cloud. Precipitation is when the water falls down and collects in rivers, lakes, streams and oceans. Now you understand how you could be drinking water from ages ago.
