3. Do surface currents in the Northern hemisphere flow clockwise or counter clockwise?
4. What about in the Southern hemisphere?
5. Which major current affects the eastern coast of the U.S.?
6. Is it warm or cold?
7. Which direction does it flow?
8. What effect does it have on the climate on the east coast?
9. What effect would it have on the climate of the east coast it flowed in the opposite direction?
10. Which major current affects the SOUTHwest coast of the U.S.?
11. Is it warm or cold?
12. Which direction does it flow?
13. What effect does it have on the climate on the southwest coast?
14. Which major current affects the NORTHwest coast of the U.S.?
15. Is it warm or cold?
16. Which direction does it flow?
17. What effect does it have on the climate on the northwest coast?
18. New Foundland, Canada has a sub-arctic climate, and London, England has a mild climate.
How is this possible if these two places are located at the same latitude?
19. What effect does the Brazil Current have on the climate of Brazil?
20. What effect does the Peru Current have on the climate of Peru?
21. What effect does the Kuroshio Current have on the climate of Japan?
22. What other city on your map has a similar climate to Los Angeles, CA because of the ocean
currents that affect it?
23. Why is the climate in Charleston, SC so much warmer and more humid than the climate in Los
Angeles, CA?
24. Ben Franklin was the first man to map the Gulf Stream. How did this knowledge help him to get
the mail to Europe quickly? (Remember: Ships only had sails back then!)
25. According to your map, why did it take longer to mail back to the U.S. from Europe?
Picture yourself standing at the shore of each of the places listed in the chart. You throw a bottle witha message in it into the ocean. Where might the ocean's currents carry your message? (HINT: Wherewill it make landfall?) Use your ocean currents map as a reference.
