2.2 Cycles Of Matter

  1. 1. Cycles ofCycles of MatterMatter Mr. SchumaierMr. Schumaier
  2. 2. What are the three most important cycles of matter?
  3. 3. The Three important cycles of matter are: The Water Cycle The Carbon & Oxygen Cycles The Nitrogen Cycle
  4. 4. What is the WATER CYCLE?
  5. 5. A continuous process where water moves from the Earth's surface to the atmosphere and back.
  6. 6. What three major processes make up the water cycle?
  7. 7. The three major processes are evaporation, condensation, and precipitation.
  8. 8. What is EVAPORATION?
  9. 9. Process where liquid water changes to a gas state. Energy for evaporation comes from the sun.
  10. 10. What is CONDENSATION?
  11. 11. Process by which a gas changes to a liquid state. Will eventually form clouds.
  12. 12. What is PRECIPITATION?
  13. 13. Drop of liquid that fall back to the Earth. Rain, Snow, Sleet, Hail,
  14. 14. What change of state occurs when water from the surface of the ocean enters the atmosphere as water vapor?
  15. 15. Evaporation
  16. 16. How is carbon dioxide used by producers?
  17. 17. Producers use carbon from carbon dioxide to produce other carbon-containing molecules.
  18. 18. How is oxygen returned to the environment?
  19. 19. Plants and other producers release oxygen as a byproduct of photosynthesis.
  20. 20. What is NITROGEN FIXATION?
  21. 21. Process of changing free nitrogen gas into a usable form of nitrogen
  22. 22. What are NODULES?
  23. 23. Bumps on the roots of plants where bacteria live. The plants include clover, beans, peas, alfalfa, and peanuts.
  24. 24. How is nitrogen fixation a necessary part of the nitrogen cycle?
  25. 25. Most organisms cannot use free nitrogen in the atmosphere. Nitrogen fixation combines free nitrogen with other elements to form compounds that organisms can use.
  26. 26. Explain how the movement of matter through an ecosystem is different than the movement of energy through an ecosystem.
  27. 27. Matter can be recycled over and over again. In contrast, once energy has moved from the producers to the consumers and then the decomposers, it cannot be recycled. A new supply must be “captured” by the producers.
  28. 28. Water Cycle Jump
  29. 29. The EndThe End
