1. The sun heats water and turns it into water vapor.
The sun heats water and turns it into water vapor, which is the first step of the water cycle called evaporation.
2. When water vapor goes up into the sky, it forms clouds.
When water vapor rises and cools, it forms clouds made of tiny water droplets.
3. When clouds get heavy, rain falls from the sky.
When clouds get heavy with water, rain falls from the sky as precipitation.
4. Water that falls from clouds is called precipitation.
Precipitation is the water that falls from clouds in the form of rain, snow, sleet, or hail.
