7. When nitrogen from the atmosphere enters the soil
12. When dead animals decompose and nitrogen is converted in inorganic forms.
17. The process where water moves above, on, and below the Earth's surface
19. This is the most abundant element in our atmosphere, making up 78% of it.
20. How does carbon move from the atmosphere to plants?

1. 3% of the water on the Earth is this.
2. When dissolved nitrogen is returned to the atmosphere
3. The process where water vapor is converted back into liquid water.
6. When burned, these release carbon and other greenhouse gases into the atmosphere; coal, oil, gas, etc.
8. These gases trap heat in the atmosphere; carbon is one of these gases.
9. How does carbon move from plants, to animals, to more animals?
10. 97% of the water on the Earth is this.
11. This force of energy converts nitrogen into forms that are usable by plants and animals
13. The form of nitrogen in which it can be used by plants
14. The part of Earth's spheres where water is present
15. When nitrogen is transformed into a form that can be used by plants
16. How does carbon move from living things to the atmosphere?
18. How does carbon move through the different spheres?
21. The process where water is converted from its liquid state to its gas state of water vapor
