GEOL 31 - Physical Oceanography Exam # 1 Study Guide - Spring 2012 exam date: Thursday, March 8, 2012 Professor: Dr. Alessandro Grippo, Ph.D.   General Information Last Updated  •  March 3, 2012    PLEASE NOTE: Only students who are enrolled in the class can take the test. If you are not enrolled, for any reason (and in particular, if you have been given an add code and have not used it yet) YOU CAN NOT TAKE THE TEST. You CAN NOT USE cellular phones, iPods, Blackberries, Bluetooth, headphones, computers, pocket calculators, translators or, in general, ANY KIND of electronic device during the test. All electronic devices MUST BE TURNED OFF: if a cell phone rings, or if a device is on during test time, you will not be allowed to finish your test and your result will be invalidated. You can not use any text, notes, dictionary, pocket calculator, flash card, or any source of information other than your brain. You will NOT need a ruler or a blue book for this test. You will ONLY need to bring: one Scantron, Form 882-E a number 2 pencil an eraser This study guide must be interpreted (literally) as a guide to the study of the subject and not as a listing of possible questions. On this study guide, there is no additional or extra information compared to what has been said, discussed, shown, illustrated in class. It is YOUR personal responsability to cover the materials listed below in the lecture textbook, in the website pages, and in your notes. I would strongly recommend that you peruse your notes for completeness of information: some information that has been detailed in class might only be mentioned briefly on the textbook, and you are responsible for covering that. At the end of each chapter in your textbook, there is a section called Chapter in Review. After reading the whole chapter, summarize it by reading this section, so that you can build a background on which all the info presented in the chapter stands. Know what are the key terms and the main concepts for every chapter. Test yourself with the questions for review also found at the end of each chapter. Try to work with the Critical Thinking Exercises. Take advantage of the web resources the publisher put online in association with your textbook. Try to work with other fellow students if you find it useful. Never hesitate to ask me questions in class.

Read What is Rational Use of Technology? Chapter 1 - Introduction to Planet "Earth" Study the whole chapter Know How Many Oceans Exist on Earth? among other things, know the names of the oceans and their main characteristics Read How Was Early Exploration of the Oceans Achieved? Read What is the Nature of Scientific Enquiry? Know How were Earth and the Solar System Created? know in particular thge section on Earth's Internal Structure Know How Were Earth's Atmosphere and Oceans Created? Know Did Life Begin in the Ocean? Know How Old is the Earth? Chapter 2 - Plate Tectonics and the Ocean Floor Study the whole chapter Know the introductory paragraph Know What Evidence Supports Continental Drift? be sure to know the four lines of evidence of Wegener and the objections to his theory Know What Evidence Supports Continental Drift? Know What Features Occur at Plate Boundaries? be sure to know this section well Know Testing the Model: What are some Applications of Plate Tectonics? Know How Has Earth Changed in the Past, and How Will it Look in the Future? Know Plate Tectonics ... to be Continued Chapter 3 - Marine Provinces Study the whole chapter Know What Techniques are used to Determine Ocean Bathymetry? know about soundings, echo soundings (including the different tools such as PDR, Seabeam, Sea MARC, GLORIA), and seismic reflection techniques. Know section 3.1 on pages 78 and 79, Sea Floor Mapping From Space. For instance, check the difference between the bathymetric maps made with echo sounders and those made with satellite data in Fig. 3B, page 78. Know What does Earth's Hypsographic Curve Reveal? hint: what do the flat portions and the slopes of the hypsographic curve seem to suggest? Know What Features Exist on Continental Margins? among all other things, know about: passive margins and active margins (both convergent and transform) the continental shelf: know the main characteristics, know the relationship between the kind of margin and the kind of shelf, know about the continental borderland the continental slope submarine canyons and turbidity currents the continental rise: know what turbidite deposits are, what is graded bedding, what is a submarine, or deep-sea, fan Know What Features Exist in the Deep-Ocean Basins? among all other things, know about: abyssal plains: flat features formed by sediment deposition volcanic peaks in the abyssal plain: seamounts vs. tablemounts (or guyots); abyssal hills, or seaknolls, and abyssal hill provinces ocean trenches Know What Features Exist Along the Mid-Ocean Ridge? among all other things, know about: rift valleys the difference between an ocean ridge and an ocean rise pillow lavas, or pillow basalts the relative high frequency of mid-ocean ridge volcanic eruptions hydrothermal vents (warm-water vents, white smokers, black smokers) deep-ocean ecosystem around hydrothermal vents centered on non-photosynthetic bacteria transform faults and fracture zones: what is the difference between the two? the three kinds of oceanic islands islands associated with the mid-ocean ridge islands associated to hot spots islands that are part of an arc and are associated with convergent plate boundaries (notice that islands can also be part of a continent, and as such they do not occur in the deep ocean) Go back to the home page       Go back to the Spring 2012 page
