  3. Mr. Harvey Earth Science 4 / 6 / 11 • OBJECTIVES • Describe the relationship between winds and surface currents. • Describe patterns of different types of surface currents. • Describe the flow of density currents. • Identify factors that affect the density of ocean water. • CHAPTER 24, SECTION 1 & 2 • PAGES 532 - 539

  4. Section 2 Review Pages 492 - 494 The normal pH range of blood in the human body is between 7.35 and 7.45. A pH below 6.8 or above 7.8 is deadly. Form a hypothesis describing how the body maintains a steady pH despite environmental changes. Describe three ways that polarity of water molecules affects the behavior of water.

  5. Section 3 Review Pages 495 - 498 Describe two ways to measure salinity. Explain how salt extracted from seawater might be different from common table salt.

  6. Section 4 Review Pages 499 - 502 In addition to providing a food source, in what other ways do phytoplankton affect the lives of marine animals? Describe one way that zooplankton help recycle ocean resources. Describe two ways in which people can protect the environments of marine organisms.

  7. Page 532 Describe the difference between an ocean current and a surface current.

  8. In what general direction do cool currents flow? In what general direction do warm currents flow? Page 532

  9. Page 533 Which winds create the North Equatorial Current? Which winds create the North Atlantic Drift?

  10. Page 536 At what locations do deep currents rise to the surface? Where do surface currents sink to become deep currents?

  11. Page 537 How far does the North Atlantic Intermediate Water extend? Which current is densest? Which currents are closest to the surface water?

  12. Page 538 Why is the salinity of the water in the Mediterranean higher than that of the water in the Atlantic? How does salinity affect the density of water?

  13. Page 539 Describe two causes of upwelling.

  14. Section 1 Review Pages 532 - 535 What is the primary cause of surface currents? What type of Gulf Stream ring is found between the Gulf Stream and the coast Of the United States? List two examples of countercurrents.

  15. Section 2 Review Pages 536 - 539 Why are density currents so important to marine life in the deep ocean? Where does the densest water in the ocean come from? Explain why. Antarctic Bottom Water has a temperature of 31 degrees F. Why does it not freeze?

  16. Homework COMPLETE THE ASSIGNMENT USING PAGES 492 – 503. THE ASSIGNMENT IS DUE BEFORE CLASS BEGINS ON FRIDAY. READ PAGES 532 – 543. EMAIL ME AT MHARVEY@PACYBER.ORG TUTORING TUESDAY & THURSDAY FROM 8AM-9AM & 10:30AM-11AM
