STUDY GUIDE FOR GEOL 1020 Exam 2 – Fall, 2008 The content of the 2 nd exam will follow the content of the lectures to this point. It will concentrate on material we’ve covered since Exam 1, but it is comprehensive . I could ask about anything covered since the beginning of class. Questions on anything discussed in the assigned readings are possible but the exam with concentrate on the themes we developed in class. Expect the exam to have about 40 questions. In keeping with my comments in the first paragraph, I would suggest that your study strategy should emphasize doing all you can to become comfortable with what we’ve discussed in lectures (including clicker questions) and labs. However, don’t ignore the readings from the book or the reserve readings. These materials cover many of the same topics in a different way and they can be very useful in helping you to understand the material covered in the lectures. OUTLINE OF MATERIAL COVERED SINCE EXAM #1 1. Early Proterozoic tectonics a. What was the earth’s temperature then? b. By what time was plate tectonics operating in the same way it is today? c. When and how was Colorado’s continental crust added to the North American continent? d. What clues do Colorado’s Early Proterozoic rocks provide that reveal how and when this material was formed and how it was attached to North America? e. What proportion of the globe was covered by continental crust at the close of the Early Proterozoic? 2. Early Proterozoic life and climate a. What is the significance of BIFs and stromatolites in the Early Proterozoic rock record? b. What organisms contributed to BIF and stromatolite formation and in what way did they change the earth? c. When and how did oxygen accumulate in the atmosphere and what were significant effects of that buildup? d. How do geologists determine the paleolatitude of a rock? e. What major life innovation occurred during the Early Proterozoic and how was it accomplished? f. What is the primary difference between a prokaryotic and a eukaryotic cell? g. What evidence supports the endosymbiotic theory for the evolution of eukaryotes? 3. How to deduce depositional environment, paleogeography, paleoclimate, and ancient current or wind directions from the characteristics of sedimentary rocks a. What are the key surface characteristics of the ancient earth that we can reconstruct using the evidence contained in sedimentary rocks? b. What are the specific grain characteristics in sedimentary rocks that contain clues to the past and what about the environment does each one reveal?
