GEOS212: Introduction to Oceanography NAME ____________________________ EXAM 2: Fall 2017 – Practice Exam Good luck on your exam! The ground rules are simple – you may not use any books, notes, calculators, conversations, or anything but what is in your own head to answer these questions. BEFORE YOU DO ANYTHING ELSE, put your name on all 3 pages of this exam. Read all questions carefully and answer them completely. In my experience the failure to read questions carefully has been the single biggest reason that people lose points on a test. Section 1: Multiple Choice Slides (2 points each, USE CAPITAL LETTERS!) 1. _________ 11. _________ 21. _________ 2. _________ 12. _________ 22. _________ 3. _________ 13. _________ 23. _________ 4. _________ 14. _________ 24. _________ 5. _________ 15. _________ 25. _________ 6. _________ 16. _________ 7. _________ 17. _________ 8. _________ 18. _________ 9. _________ 19. _________ 10. _________ 20. _________ CONTINUE TO NEXT PAGE

Section 2: Draw and Label Diagrams 1. (10 points) On the following map, indicate one latitude where you find deserts (with a D), and the direction of air motion (up or down) at that latitude. Indicate a location with upwelling from 100m (U). Draw a circle with arrows showing the location and direction of flow in the North Atlantic Subtropical Gyre (NA). Indicate the location and direction of the Southern Hemisphere Westerly winds (W). Indicate a location with coastal downwelling due to a Westerly wind (CD). Indicate the location where tropical storms are called Typhoons (T) and indicate the location of the East Australia Current (EAC)

2. (5 points) Indicate with arrows the direction of water motion at the surface, at the bottom and at the coast. Label the diagram as either upwelling or downwelling. Name two features about water along the coast (e.g. warm, cold, productive, low nutrients, etc.)

Geos 212 - Exam 2 NAME _________________________________ 3. (10 points) Please draw the diagram with waves approaching a beach at the indicated angle. Indicate or describe the change in wavelength and wave speed after the waves cross the Wave Break (WB). Indicate with arrows the path of sand in the Surf Zone as waves come in and go out. Indicate with a BIG ARROW the direction of the longshore sediment transport. 4. (10 points) A) Draw the profiles of Pressure, Temperature, and Light in the atmosphere and ocean. Please also include the profile of Humidity in atmosphere and the profiles of carbon dioxide (CO2) and oxygen (O2) in the ocean. B) How deep is the Photic Zone in the ocean? ___________ CONTINUE TO NEXT PAGE

5. (10 points) From the “Big Bad Table”, you find out that a storm (at point S) with 45 mph winds individual generates waves traveling at 20 mph. If it is 1500 miles from point S to Australia (A), how long will it take a set of waves generated by the storm to arrive at the coast of Australia? Give your answer in hours. Show all your work.

6. (5 points) What is the definition of a “fully-developed sea”? ________________________ ______________________________________________________________________________ ______________________________________________________________________________ CONTINUE TO NEXT PAGE
