GEOL 4 - Physical Geology (with Lab) Exam # 3: Study Guide - Winter 2012 exam date: Thursday, February 9, 2012 - 8:30 AM sharp Professor: Dr. Alessandro Grippo, Ph.D.   General Information Last Updated  •  February 5, 2012 PLEASE NOTE: Cellular phones, iPods, Blackberries, Bluetooth, headphones, computers, pocket calculators, dictionaries, translators or, in general, ANY KIND of electronic device CAN NOT be used during the test. All electronic devices MUST BE TURNED OFF: if a cell phone rings, if a light is visible, or a device is on while in class 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 for this test. You can not wear a hood during the test, hide your ears or have anything in them at any time. You will ONLY need to bring: one Scantron, Form 882-E a number 2 pencil an eraser your Geology/Mineralogy 2 x 2 glass (if needed, you will access to a streak plate, magnets and HCl bottles) This study guide must be interpreted (literally) as a guide to the study of the subject and not as a listing of possible questions. It is YOUR personal responsability to cover the materials listed below on the lecture textbook, on the lab textbook, on the web pages, and on your notes. I would strongly recommend that you peruse your notes for completeness of information: some information that has been detailed in class is only mentioned briefly on the textbooks, and you are responsible for covering that; know what the key terms and concepts are; exercise with the questions for review found at the end of each chapter. Review the materials from your labs. Read the summary at the end of each chapter, try to answer review questions, try to work with other fellow students if you find it useful. Never hesitate to ask me questions in class or during the lab.

Chapter 13 - Deserts and Wind Action Know the Introduction Know Distribution of Deserts Review your notes for a more thorough understanding: We discussed wind patterns on a non-rotating Earth with no continents We then moved on to a rotating Earth (Coriolis effect: remember what happens in the two hemispheres, also in terms of general ocean circulation) We then observed the four different reasons for the existence of deserts (do NOT confuse these reasons with the characteristics of deserts, which is the next paragraph) We also discussed general precipitation patterns, humidity of the atmosphere, winds, high and low pressure We discussed shallow-ocean circulation and deep-ocean circulation (see the appropriate, related sections on the Oceanography web page) Know Some Characteristics of Deserts Know Desert Features in the Southwestern United States Know Wind Action In addition to the paragraph materials, study the section Desert Pavement and Desert Varnish (Earth Systems 13.3, page 353, or 13.2, page 352 on the 11th edition) Chapter 14 - Waves, Beaches, and Coasts Know the Introduction Know Water Waves Know Near-Shore Circulation Know Beaches Know Longshore Drift of Sediment Know Coasts and Coastal Features   Study Guide, part 2: Lab Last Updated  •  February 5, 2012 For the lab part of this test you will have to identify (name) a few different rocks, igneous, metamorphic and sedimentary, and then also answer a few general questions. Rock Identification: You will be given a few rocks to identify. These rock types will be chosen among the ones you have already seen, identified and checked during previous labs. You will need to bring your 2x2 glass ONLY (plus pencil, eraser and scantron). Streak plates, HCl bottles and a magnet will be available.
