Water is everywhere on Earth and is used a lot in our lives. But, the amount of water on Earth has actually stayed the same and will be the same for the next coming years! This is because of the water cycle. The water cycle is made up of evaporation, condensation, precipitation, and run-off. Evaporation is when water evaporates from the ground. This is when the sunlight heats the water and turns it into a gas called water vapor. Condensation is when the water vapor rises in the air and gets cooler. This causes it to turn back into a liquid. This process forms clouds. Precipitation is when the liquid water falls to the ground. This happens when a cloud becomes heavy and all the water will fall to the ground. Run-off is when precipitation (snow, rain, sleet, or hail) hits the ground and drains into rivers, lakes, and oceans. This run-off is what causes accumulations or build-ups of water. Because of the water cycle, the water on Earth stays the same. It is only in different places of forms. We are drinking the same water that the dinosaurs may have drank!!
