Water cycle: 3 major processes • http://techalive.mtu.edu/meec/module01/Thehydrologiccycle.htm
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
Ocean function • Absorb solar radiation • Stores energy • Regulates temperature
Freshwater • Is not usually green • 3% • Most in icecaps / glaciers • Groundwater 1%
Biosphere “The sweet spot” • Oxygen & water • Moderate temp • Energy
And then… • Homework SR 3.2 & 3.3 • Next class: loose ends • Review for test (11/28 & 11/29)
