2. Time’s Up! 1.Turn in your climate analysis worksheet to the basket, if you didn’t turn it in last week. 2.List 7 factors that influence local climate. 3.What are the gyres?

4. What evidence do you find that wind influences the direction of the surface currents in the ocean?

5. What pattern can you see in the direction of the global winds?

6. Notice the location and flow of warm and cold ocean currents. Why do you suppose that currents flowing toward the equator are generally cool while currents flowing away from the equator are warm?

8. Surface Currents and Climate

9. Marlin and Dory are tropical fish. How could they possibly be expected to survive as far south as Sydney?

10. Would you want a wet suit if swimming off the coast of Namibia or Angola? Explain.

11. Hurricanes have been known to strike North America as far north as Maine and Nova Scotia. How is that possible? If Earth spun the opposite way, what changes would you expect to see in California’s weather?

12. Research Can climate be predicted using ocean surface currents and latitude? Each group will be assigned a costal city. Use latitude as well as ocean surface currents to explain the climate of your city. Report your results on the class padlet (link on bell-science.com)

13. The 5 Gyres

17. What is upwelling? What causes it?

18. Upwelling (0:50)

20. Upwelling Rise of cool nutrient rich water Drives costal ecosystemecosystem

21. Water Density Investigation

22. Thermohaline Circulation Deep ocean currents Ocean’s “conveyor belt” Driven by changes in temperature and salinity

24. What would happen to the thermohaline current if all of the arctic ice melted back into the ocean?
