Water's Role on Earth

3. Precipitation, infiltration, and run-off are all a product of this force.
7. Process where water goes from a gas (water vapor) to liquid water (clouds, dew droplets, etc.).
11. Form of nitrogen able to be absorbed via the roots of plants (use plural form)
13. Overtime, humans have drastically increased the percent of ground-cover that does NOT allow water to penetrate due to urbanization (more concrete, cement, & buildings, etc.).
16. Property of water that describes how the density decreases when it freezes.
17. Use of this synthetic compound on crops and plants in the last century has contributed to dead zones around the world.
18. Process where precipitation causes excess fertilizer, animal waste, and sewage goes into the waterways.
19. Process where water goes from a liquid to a gas (water vapor)
20. Variable that is kept constant

1. Evaporation, transpiration, and condensation and all a product of this force.
2. Property of water that allows it to absorb/release a lot of energy with minimal temperature change
4. Variable that is observed and recorded
5. Process where water evaporates from plants.
6. Property of water that allows light to pass through it.
8. Process where water goes from the surface of the earth to the ground water (aquifer).
9. Organism responsible for converting nitrogen into various forms
10. Lack of oxygen in the water, no life
12. Variable that is changed/tested
14. Excess nutrients in water or soil
15. Property of water that allows various solids to be dissolved in water
