GEOL 1 - Physical Geology Exam # 3: Study Guide - Summer 2008 exam date: Thursday, July 24, 2008 - 8.00 AM sharp Professor: Dr. Alessandro Grippo, Ph.D.   General Information Last Updated  •  July 17, 2008 NOTE: Cell-phones, electronic devices of ANY sort, dictionaries, books, notes, flash cards or any other material not explicitly allowed below CAN NOT be used for any reason during the test and should not be kept on the desk. Unless there is a REAL emergency, you can not leave the room before you completed your test. This test also includes a small section with questions from the previous chapters. The questions (possibly coming from any chapter 1 through 10), will focus on the main essential concepts detailed in those chapters. 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. It is YOUR responsability to cover the materials listed here on the lecture textbook and your notes. I would strongly recommend that you peruse your notes for completeness of information: some concepts have been expressed with much more detail in class than are explained on the book, and you are responsible for that; know what the key terms and concepts are (see the list at the end of each chapter on your textbook); exercise with the questions for review also found at the end of each chapter. Read the summary at the end of each chapter, try to answer review questions, try to work with other students if you find it useful. Never hesitate to ask me questions in class or during the lab   Study Guide Last Updated  •  July 16, 2008 Chapter 10 - Streams and Floods Part of this chapter, from page 247 to page 257, was covered in th eprevious test. These pages will NOT be object of the new materials you have to know for this test. You will still have to know the basic facts for the cumulative part of the test. Start studying again on page 257 ("Stream Deposition"), skip "Flooding" (see below), and study the rest of the chapter. Know Stream Deposition (including all kinds of depositional bodies) skip the paragraph on Flooding (pages 267 to 272) Know Stream Valley Development Know Superposed Streams (not on textbook, but detailed in class) Chapter 11 - Ground Water Know the Introduction Know what groundwater is Know what porosity and permeability are, and how they differ; know which rocks are or are not porous and/or permeable; know about primary and secondary porosity know about the water table, the movement of ground water, aquifers, wells, springs and streams skip the paragraph on contamination of ground water (pages 292 to 296) Know Balancing Withdrawal and Recharge Know Effects of ground-water action, with special attention to the chemical equations that describe calcium carbonate / bicarbonate / carbon dioxide equilibria Know about Karst Landscapes Know Hot Water underground Chapter 12 - Glaciers and Glaciation This chapter was expanded in class with a discussion on the possible reasons for climate change (among others: a different distribution of oceans and land masses, variations in the rate of volcanic activity, variations in the amount of solar radiation reaching Earth over time) that is part of the materials on which you will be tested. You should have your notes but there is also a brief summary in Box 12.5 on the textbook (page 330). I also added a reference figure on the web on Milankovitch cycles (it is the last figure, at the bottom of the page) Also, I would suggest to integrate your knowledge by reading Box 12.1 (page 313), Box 12.3 (pages 318-319) and, to better understand what happens when velocity and discharge of water increase abnormously, Box 12.6 (page 333). Finally, when studying varves, do not forget their meaning and utility in terms of geologic time. Know the Introduction Know Glaciers - Where they are, how they form and move Know Glacial Erosion Know Glacial Deposition Know Past Glaciation (integrate this paragraph with Box 12.5, page 330) Chapter 13 - Deserts and Wind Action For this chapter, there was a thorough discussion in class on atmospheric circulation (air pressure and temperature, humidity - or amount of water vapor in the atmosphere, patterns of precipitation and fair weather, etc.) on a non-rotating Earth and then on a rotating Earth (Coriolis effect). We also briefly discussed surface ocean currents, as opposed to deep ocean currents. Peruse your notes on these concepts. One common mistake is to confuse the reasons why we have deserts with the characteristics of a desert. For instance, internal drainage (page 341) is characteristic of a desert, but it does not cause the existence of a desert. Also, know where the main deserts of the world are (see figure 13.3, page 341) Know the Introduction Know the Distribution of Deserts Know Some Characteristics of Deserts Know Desert Features in the Southwestern United States (that is, be able to distinguish and identify the characteristics of the Colorado Plateau and of the Basin and Range deserts). Review the notes you took after the projection of the Death Valley movie. Know Wind Action Know Box 13.3 (page 353). Desert Pavement and Desert Varnish 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 Chapter 15 - Geologic Structures You can integrate your study with Box 15.2 (pages 400 to 402), that deals with the San Andreas Fault (which was the destination of one of the Geol 35 Field Trips during the Spring 2008 semester). Also, be able to identify geologic structures such as anticlines, synclines and faults from simple geologic maps, integrating your knowledge of structures (from this chapter) with your knowledge of stratigraphy (from chapter 8) Know the Introduction Know Tectonic Forces at Work Know Structures as a Record of the Geologic Past know Folds Know Fractures in Rocks
