Across
- 5. Carbon moves from living things to the atmosphere
- 6. process which water vapor is changed back into liquid water
- 8. this element is part of seawater, atmosphere, coal etc.
- 9. This cycle relies on the sun and gravity to move and through around the earth
- 13. The ammonium salts are absorbed onto clay in the soil and then chemically altered by bacteria into nitrite (NO2-) and then nitrate (NO3- )
- 14. stored under the surface of the earth
- 16. travels between living and non- living things of our plants
- 17. cyanobacteria in the soil or by a bacteria that lives in the roots of certain plants known as
- 18. where most of our nitrogen is
- 19. Carbon moves from the atmosphere to the oceans.
- 21. This gets nitrogen from it's find that contain organic molecules or plants
Down
- 1. occurs because of the heat from the sun
- 2. water that falls from the atmosphere in the form of rain, sleet, snow
- 3. plants use water to help make energy, and they also lose some water to the surrounding air
- 4. Through food chains, the carbon that is in plants moves to the animals that eat them
- 7. its been an unchanging thing in our history
- 10. Carbon dioxide is a greenhouse gas and traps heat in the atmosphere
- 11. Carbon moves from plants and animals to soils.
- 12. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
- 15. determines the type of precipitation that
- 20. supplies the water cycle, can be looked at as the back bone
