The water cycle is the process of how water is generated, used, and recycled. It moves from one place to another. The water cycle circulates around the world. There are four major phases of the water cycle: evaporation, condensation, precipitation, and collection.
Evaporation is also called water vapor. Water turns into gas and goes in the air, and form clouds in the sky. The sun causes water to turn into evaporation. Water evaporates from plants, streams, rivers, oceans, grounds, skins, etc. When the water is hot, evaporation can happen rapidly. Steam can come from the water when it is hot. In some hot places such as deserts, when the rain falls, the evaporation process happens right away.
Condensation occurs as water vapor gets cold, and turns back into liquid, then it forms clouds in the sky. When a person pours a glass of cold water on a hot day, then he or she puts it outside. After a few minutes later, he or she will see a few drops of water dripping on the outside of the glass. The water doesn’t just leak from inside of the glass, but it evaporates. The water actually comes from the air.
Precipitation can be rain, sleet, snow, or hail. Precipitation falls from the clouds. It only falls from the clouds when the clouds are full of droplets. When the air is cooling down, droplets continue to join together. The droplets then become heavier and larger. Precipitation falls from the clouds into the oceans, streams, rivers, and...
