Across
- 4. water returns from the atmosphere to the earth as rain, sleet, snow, and hail
- 5. liquid water percolates down through the soil into the ground
- 6. gravity pulls liquid water in a flow of precipitation over the ground
- 7. precipitation, such as snow or frozen water, instantaneously changes from ice to gaseous water vapor
Down
- 1. water vapor molecules come together and cool, forming liquid water
- 2. liquid surface water is heated by the sun and goes into water vapor
- 3. liquid water within plants is heated by the sun and evaporates through openings in their leaves
