GEOL 1 - Physical Geology Exam # 2 Study Guide - Summer 2007 Thursday, July 12, 2007 Professor: Dr. Alessandro Grippo, Ph.D.   General Information Last Updated  •  July 7, 2007 NOTE: 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 study and not as a listing of possible questions. It is YOUR responsability to cover the materials listed here on the lecture textbook, the lab textbooks and your notes, including those you have taken during the projection of movies. I would also strongly recommend that you peruse your notes for completeness of information; 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.   Study Guide Last Updated  •  July 7, 2007 Chapter 6 While you will not be directly tested on materials from the previous chapters and paragraphs, you should be familiar by now, among other things, with the main points of the theory of plate tectonics, igneous rocks and sedimentary rocks. We stopped at page 155 for the previous test and that is where we start from for this second one. Know Sedimentary Structures, what they are, different types, and what they might indicate Know Fossils. Read Formations. We mentioned this in class; there will be no direct questions on this paragraph but you need to be able to tell what a formation is. know Interpretation of Sedimentary Rocks: both Source Area and Environment of Deposition. Be able to distinguish between the different environments and know what is characteristic in each one of them Know Plate Tectonics and Sedimentary Rocks. Notice on page 165 a box on Transgression and Regression, discussed in class together during the lectures on Chapter 8. Chapter 7 Know the introduction to the chapter. Know the factors controlling the characteristics of metamorphic rocks. Know the classification of metamorphic rocks. Know the types of metamorphism. Know plate tectonics and metamorphism. Know hydrothermal processes. Chapter 8 - Time and Geology Study the whole chapter; and know in particular: what uniformitarianism and actualism are; the difference between relative and absolute age all the principles that are used to determine relative age; what contacts and formations are be able to reconstruct a stratigraphic sequence know all kinds of unconformities and what they represent know what correlation is and all the methods used to correlate rocks know what fossils are (see also chapter 6), and why and how they are used in correlation know the concepts of transgression and regression, and how it can be seen in the rock record know what certain lithologies stand for, roughly speaking, in terms of paleoenvironments (again, see also chapter 6) know the Geologic Time Scale: as a concept and all of the Eras with their numerical age boundaries know the Periods of the Paleozoic and the Mesozoic know Numerical Age, including Isotopic dating and uses of Isotopic dating know how to combine relative and numerical ages Chapter 9 - Mass Wasting know what mass wasting is and how it is classified know what the controlling factors in mass wasting are know the common types of mass wasting know how to prevent landslides Chapter 10 - Streams and Floods know what happens in the hydrologic cycle; be prepared to discuss what happens in case of global warming or global cooling know the paragraphs on channel flow and sheet flow know what drainage basins are, and know the four main drainage patterns know the factors that affect erosion, transportation, deposition be prepared to solve simple problems concerning discharge be prepared to answer questions concerning how sedimentary grains of different size behave when subject to stream currents of different velocity know about stream erosion, transportation and deposition (including all kinds of depositional bodies) skip the paragraph on flooding study stream valley development, stream terraces, incised meanders, superposed streams
