| Learner Objectives The student will: 1. Describe the two bases for delineation of pelagic zones. 2. Identify the zones and their boundaries of the pelagic realm. 3. Identify location of DSL and explain why it changes with a diurnal pattern. 4. Distinguish between thermocline and isotherm. 5. Identify the benthic zones and their boundaries. 6. Locate the 4 major divisions of the world ocean. 7. Distinguish between ocean and seas. List the 2 types of seas and give some examples of each type. 8. Distinguish between oceanic crust and continental crust. 9. Explain the concept of isostasy. 10. Describe Pangaea, Panthalassa, Laurasia,
Gondwanaland, and the Tethys
11. Describe how the concept of Pangaea can be verified. 12. Define plate tectonics. Plate tectonics: deformation of the earth's surface of lithospheric plates by the forces generated by the heat flow of the Earth's interior. 13. Explain the 3 processes of plate tectonics. 14. Describe the basic geomorphology of the ocean floor.
Continental shelf, continental slope, abyssal plains, submarine
ridges, seamounts, trenches, 15. Identify the range of temperatures that most organisms are able to tolerate. Give the relationship between temperature and metabolic processes. Q10: 0-40oC; metabolic processes > x2 for each 10oC rise in temperature in poikilotherms. 16. Explain the difference between poikilothermic organisms and homeothermic organisms. 17. Identify the biogeographical zones of the ocean. 18. Explain the relationship between thermoclines and pyncoclines. 19. Identify 2 types of motion produced by winds. 20. Describe waves. 21. Explain how waves are formed. 22. Explain the 3 factors which determine the amount of energy gained by waves. 23. Describe wave types and the forces that affect them. 24. Distinguish between free and forced waves. 25. Explain wave interference patterns. 26. Explain why longshore currents and rip currents are opposite phenomenon. 27. Distinguish between offshore, nearshore, and shore (foreshore, backshore). 28. Explain how tides occur and distinguish between spring, neap, semidiurnal, mixed semidiurnal, and diurnal tides. 29. Explain the concepts of upwelling and downwelling. Account for whale shark migration patterns. 30 Describe and distinguish between tsunamis, typhoons, and hurricanes. Describe internal waves and compare internal waves to storm waves. Describe the effect of storm waves on the neritic zone.. 31. Identify and describe the from the Labrador current. Explain how eddies occur and the effect they have on planktonic communities. Identify the analogous current in Pacific. 32. Explain how Perfect Storm occurred and why its effects were devastating to the fishing industry. 33. Describe the circulation of currents at the Poles. Explain why large masses of ice break free and where they are carried. Explain why there are penguins in the Antarctic and polar bears in
the 34. List and describe depositional geomorphological features of the coast. 35. Explain how barrier islands are formed. 36. Describe the major physiographic zones of a barrier island. 37. Explain how delta formation differs from depositional features.
