Across
  1. 5. hot iron and nickel center of the earth
  2. 7. effect greenhouse gasses absorb heat and trap it in earth’s atmosphere. Greenhouse gasses act as a blanket for the earth.
  3. 8. the hot interior of the earth.
  4. 9. from a gas to a solid
  5. 10. the areas of the planet that are habitable for life.
  6. 11. in animals, the process of burning sugar in oxygen to release energy. Carbon dioxide is produced, as well.
  7. 14. liquid to gas
  8. 16. cells single cells that control the opening and closing of the stomata
  9. 17. the layers of air surrounding the planet.
  10. 19. the process in which plants breath in carbon dioxide and take in water, then ‘cook’ it in sunlight to produce sugar and oxygen.
  11. 21. process of squeezing deposited sediment.
Down
  1. 1. all of the water on the planet
  2. 2. the process of dropping off and building up layers of sediment.
  3. 3. fuel coal, oil and natural gas. Created from sedimentary rock created from organic matter such as plants in ancient swamps.
  4. 4. water storage water that is stored underground in rocks called aquifers
  5. 5. when fossil fuels are burned in oxygen. It produced carbon dioxide.
  6. 6. evaporation of water through plants.
  7. 12. opening on the underside of leaves through which water transpires
  8. 13. where tectonic plates meet. They are the cracks between the plates.
  9. 15. the outer cool layer of the earth.
  10. 18. process of hardening compacted sediment into rock.
  11. 20. plates sections of the earth’s crust.
