Explanation should include
- defining water cycle: the repeated circulation of water from the atmosphere to the earth and back to the atmosphere
- understanding that the amount of water does not change but its location does
- listing the steps in the cycle
- Water is heated by the sun.
- The heated water evaporates into the atmosphere.
- Clouds form in the atmosphere.
- Clouds move over land and moisture condenses.
- Moisture is released as rain, snow, sleet, or hail.
- Water falls to land and (1) runs off to streams, rivers, groundwater, and oceans, or (2) is absorbed by plants and released into the atmosphere by transpiration, or (3) is used by animals and humans.
