  1. CYCLES QUIZ REVIEW

  2. What are carbonates?

  3. Carbonates are rocks made of calcium or magnesium and CARBON

  4. What is an example of a carbonate?

  5. LIMESTONE

  6. What is the Carbon Cycle?

  7. The process where carbon in the air is cycled between plants, animals, and the environment

  8. Is coal a carbonate?

  9. No, it has no calcium or magnesium

  10. What is coal?

  11. COAL is a rock that is petrified plants. Ican be up to 98 percent pure carbon.

  12. How does carbon dioxide in the air become organic carbon compounds?

  13. Plants take in CO2 and convert it to carbon compounds through photosynthesis.

  14. Animals use it in cellular respiration to obtain energy. When the breath, they exhale co. as a waste product of the cellular respiration

  15. how do carbonates and coal store carbon for long periods?

  16. They store it as stable rock that will hold it indefinitely underground

  17. Why is Limestone called a carbon sink?

  18. It takes carbon out of the environment and locks it up indefinitely

  19. What is another carbon sink that humans have been exploiting to make energy?

  20. COAL, OIL & GAS

  21. Why has the level of carbon dioxide in the atmosphere been increasing over the centuries?

  22. Fossil fuels that have held carbon for hundreds of millions of years are releasing CO2 when they are burned.

  23. How does the ocean remove some of the CO2 from the atmosphere?

  24. Water will naturally absorb quantities of CO2, but in so doing, it becomes acidic • Shellfish use Co2 in making their shells, which then become carbonate rock

  25. What are the environmental consequences of increased atmospheric CO2?

  26. Acid Rain • Global Warming

  27. What do plants and animals use Nitrogen compounds for?

  28. Building protein

  29. What converts atmospheric Nitrogen into nitrogen compounds that plants can use?

  30. Nitrogen Fixing bacteria

  31. In the soil on nodules that are on legume (bean family) roots

  32. How do plants with no nitrogen fixing bacteria get nitrogen?

  33. From excess nitrates that accumulate in the soil

  34. How do nitrogen compounds from plants and animals get back into the soil?

  35. Decomposed orgaincs and Doo Doo

  36. How does a small amount of Nitrogen gas NATURALLY get back into the atmosphere?

  37. Some decomposers turn nitrates into CO2

  38. It stays in the environment in the soil, water, and living organisms

  39. What do animals use phosphorus for?

  40. Bones and teeth

  41. Where do plants get phosphorus?

  42. Small amounts of phosphorus salts wash out of rocks and soil

  43. Where do animals get phosphorus?

  44. From eating plants

  45. Does the phosphorus cycle occur in the atmosphere?

  46. From water that has dissolved phosphorus from rocks

  47. How do plants and animals put phosphorus into the soil?

  48. Decomposers release it when plants and animals die.

  49. Why does much phosphorus accumulate on the ocean floor?

  50. Some phosphorus salts are insoluble in water, and it gets washed into the oceans.
