Across
- 3. Water particles cool down as they travel up into the sky.
- 6. Plants and trees 'breathe out' oxygen and water.
- 7. Water soaks through into the soil.
Down
- 1. Water travels back down from the clouds to the earth. It can be in the form of rain, hail, snow, fog, or dew.
- 2. Water that has been infiltrated into the soil travels into the river.
- 4. Water runs along the top of the soil, rock, or concrete and travels down into the river or sea.
- 5. Water heats up, giving the water particles more energy, so they move apart and change state from a liquid into a gas.
