Essential Standard:
EEn.2.3 Explain the structure and processes within the hydrosphere.
Clarifying objective:
EEn.2.3.1 Explain how water is an energy agent (currents and heat transfer).
EEn.1.1.2
• Describe daily changes of tidal impact due to the gravitational interaction between the Earth and moon.
EEn.1.1.4
• Explain differential heating of the earth’s surface (water temperature vs. land temperature)
EEn.2.3.1
• Explain how the density of ocean water is affected by temperature and how this results in major ocean currents distributing heat away from the equator toward the poles.
• Explain how coastal climates are moderated by water (due to its high specific heat capacity) in comparison to inland climates.

Essential Questions
1. What is the difference between waves, currents, and tides?
2. What causes deep currents? 3. What causes surface currents? 4. How do currents affect climate? 5. How do large bodies of water affect climate? |
Criteria for Success
Compare and contrast waves, currents, and tides.
Model how differences in density cause convection currents. Determine which way the Coriolis Force deflects currents in the Northern and Southern hemispheres. Use an ocean current map to identify places that have climates that are affected by currents. Determine the relative heating rates of land and water. |
