1 GLY 2010 - Section 51060 Name June 23, 2010 80 points Z # 24 students took exam Evolution of the Earth KEY -- Final Examination - Part 1 THIS IS A CLOSED BOOK, CLOSED NOTE EXAMINATION. ANY USE OF BOOKS, NOTES, ETC. IS CHEATING. ALL ELECTRONIC DEVICES (CELL PHONES, COMPUTERS, ETC.) MUST BE TURNED OFF AND OUT OF SIGHT. USE OF ELECTRONIC DEVICES IS CHEATING. ANY FORM OF CHEATING WILL RESULT IN AN F IN THE COURSE AND REFERRAL TO THE STUDENT CONDUCT COMMITTEE FOR FURTHER DISCIPLINARY ACTION. Answers to the True-False and Multiple choice portions of the exam must be on a BLUE SCANTRON, with your name and Z number entered and bubbled in. When you finish, check your exam. Be sure you answered all questions. You may keep Part 1 of the exam when you finish. Turn the SCANTRON into the graduate teaching assistant, along with Part 2. Numbers in red to the left of the question number are the percent of incorrect responses. Blue text is instructor comments, not on the original test. True-False - Print the letter T or F in the blank to indicate if each of the following statements is true or false. Illegible answers are wrong. (1 point each) 17 T 1. Sudden movement along faults is the cause of most earthquakes. 8 T 2. Many mountain ranges, including the Rockies, Alps, Appalachians, Urals, and Himalayas, have marine sedimentary strata at very high elevations. Indeed, the top of Mt. Everest, the highest mountain above sea-level on earth, is composed of marine limestone. Geologists believe these rocks were elevated by plate collisions tens of thousands of feet. 46 F 3. All hydrothermal vents, either white or black smokers, are associated with hot spots. Almost all hydrothermal vents are associated with spreading centers, not hot spots. 17 T 4. The continental slope is much steeper than either the continental shelf or the continental rise. 42 F 5. Mafic sediments make up most of the material on the continental shelves. Continental shelves are built of sediment from the continents, which are primarily felsic. 8 T 6. Continental shelves are wider on passive margins, like Florida, than on active margins, like Oregon and Washington. 37 T 7. Submarine valleys found on the continental shelves are often seaward extensions of river valleys on the continents.

2 29 F 8. If the angle of subduction is large, so that the subducting plate is going very steeply into the earth, the spreading ridge where the plate is produced will be located close to the subduction zone. 21 F 9. Fine sediment will have a higher angle of repose than course sediment. 0 T 10. Activities such as road building or mining may oversteepen slopes, so that they exceed the natural angle of repose. This can lead to mass movement. 50
