GEOL 1 - Physical Geology Exam # 3 (Final) Study Guide - Fall 2007 date: Wednesday, December 12, 2007, at 3.30 sharp in DH 205 (notice the different time!) Professor: Dr. Alessandro Grippo, Ph.D.   General Information - read this! Last Updated  •  November 24, 2007 NOTE: Cell-phones, electronic devices of ANY sort, dictionaries, translators, notes, books CAN NOT be used during the test. You will ONLY need to bring: one Scantron Form 882-E a number 2 pencil an eraser If you make a correction on your Scan-Tron, be sure that you erase completely your previous answer. Reading errors from the Scan-Tron machine that result from a badly erased answer can not be fixed. 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, the lab textbook and your notes, including those you have taken during the projection of movies, if any. For each textbook chapter that is going to be on the test (that is, chapters 12, 13, 14 and 15), I listed all the paragraphs you need to study. I also added a list of essential concepts you need to be able to handle. This list is intended to help you outline the main points BUT it does not imply the rest is not important. It rather signifies that once you know these essential points you will be able to get to others much more easily. To be clear, there will be questions out of every paragraph that has been indicated, not only from the list of essential concepts. 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 both your textbook and your lab manual); 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 others if you find it useful. Never hesitate to ask me questions in class or during the lab   Study Guide Last Updated  •  November 24, 2007 Previous Chapters: as you know, one third of the final test is cumulative and concerns the chapters we covered during the semester. Questions could come from any chapter but they will be more generic and less specific than for Chapters 12 through 15. 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 the Theory of Glacial Ages (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 two projections of the Death Valley movie. Know Wind Action Know Box 13.2 (page 352). Desert Pavement and Desert Varnish Chapter 14 - Waves, Beaches and Coasts Integrate your study by reading Box 14.1 (pages 376-377) Know the Introduction Know Water Waves (include also the value of Wave Steepness, which is the ratio of Wave Height over Wavelength, not explained in the textbook but discussed in class) Know Near-Shore Circulation Read Beaches (we mentioned the main features illustrated in this paragraph, which are very importaqnt to improve our understanding of the material throughout the whole chapter; while I will NOT ask direct questions out of this short paragraph, do not take this as an optional reading but rather as a strong recommendation) Know Longshore Drift of Sediment Know Coasts and Coastal Features Chapter 15 - Geologic Structures You can integrate your study with Box 15.2 (pages 398 to 400), that deals with the San Andreas Fault (which is the object of one of the Geol 35 Field Trip 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
