  10. Objectives: Part 2

  11. Water cycle: 3 major processes • http://techalive.mtu.edu/meec/module01/Thehydrologiccycle.htm

  12. Ocean water • Covers 70% of Earth’s surface • 3.5% salinity • One connected ocean (4) • Currents • Surface • wind driven • influences climate on land • Deep • slow

  13. Ocean currents

  14. Ocean function • Absorb solar radiation • Stores energy • Regulates temperature

  15. Freshwater • Is not usually green • 3% • Most in icecaps / glaciers • Groundwater 1%

  16. Biosphere “The sweet spot” • Oxygen & water • Moderate temp • Energy

  17. Closed vs. Open systems

  18. And then… • Homework SR 3.2 & 3.3 • Next class: loose ends • Review for test (11/28 & 11/29)
