GEOL 1 - Physical Geology Exam # 1 Study Guide - Summer 2007 June 28, 2007 Professor: Dr. Alessandro Grippo, Ph.D.   General Information Last Updated  •  June 26, 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  •  June 26, 2007 Chapter 1 Read and review the wholce chapter. While there will not be direct questions on a few paragraphs, you need to grasp the meaning of every concept Know Earth's layer, from both the physical and the chemical point of view, and how they differ one from the other. Be able to explain how do we know about them. Know about the magnetic field of Earth. Know about sources of heat and energy on Earth. Know about convection, plate tectonics, name and location of the main plates. Know all kinds of plate boundaries, and what happens at each one of them. Know the three kinds of rocks and their origin. Be aware of the immensity of geologic time Chapter 2 Know about atoms and elements; the atomic structure, why atoms bond, and how (kinds of bond). Know about ions, and isotopes, atomic number and atomic mass. Knoow about polar molecules, stable and unstable (radioactive) isotopes. Know the eight most abundant element of Earth's crust, and their relative importance. Know the main mineral groups present in Earth's crust. Know about silicon tetrahedra, how they bond, why they are stable or unstable; know what kind of minerals with silicon tetrahedra have what structure. Know what defines a mineral and the most important ones; know the chemical formulas of quartz, olivine and calcite. Raed the physical properties of minerals and know color: there will be no direct questions on this paragraph but be sure to read it for completeness of information and to improve comprehension of the study material Chapter 3 Know the Rock Cycle. Know Igneous Rocks. Know Intrusive Bodies. Know Abundance and Distribution of Plutonic Rocks. Know How Magma forms and how Magmas of different Composition evolve (including Bowen's reaction series: there WILL be questions on this). Know How to explain igneous activity by plate tectonics. Chapter 4 Know Pyroclastic Debris and Lava Flows. Read Living with Volcanoes. Know Extrusive Rocks and Gases, including composition and textures. Know Extrusive Rocks Know the Types of Volcanoes. Know about Lava Floods and Submarine Eruptions. Chapter 5 Know what Weathering, Erosion and Transportation are; Weathering and Earth Systems; how weathering alters rocks. Know the effects of weathering. Know everything about mechanical and chemical weathering; be sure you know what the most important agents for both kinds are; be sure to know the consequences of both kinds of weathering on different rocks, and what the most common weathering products are. Know all about Soils; be sure to know also about the properties of clay minerals. Chapter 6 Know what a Sediment is (first paragraph). Know types of Sedimentary Rocks. Know all clastic (also known as detrital), chemical and organic sedimentary rock. Be able to classify rocks (i.e., define one). Know the origin of oil and gas (stop here, at page 155: Sedimentary Structures will be in test #2).
