Final Exam Study Guide Survey of Earth Science I Instructor: Youngwoo Cho 1. What important proposition was introduced by James Hutton?  Uniformitarianism 2. What principles were introduced by Charles Lyell?  Pg. 306 3. What type of age is described below? “This age is based upon order of formation”  Superposition 4. Pictured on the left is a ripple mark that is currently forming and on the right is the ripple mark found in a sedimentary rock. What principle is implied through these samples?  Uniformitarianism 5. **Considering basic principles for determining relative age, what can you learn from the following picture?  **Professor had not given/shown the picture for this question. 6. What principle does the following picture imply?  Superposition 7. What principle does the following picture imply?  Lateral Continuity 8. What principle does the following picture imply?  Inclusions 9. What principle does the following picture imply?  Cross-cutting 10. What principle does the following picture imply?  Baked Contact 11. What is the description for the relative ages of this cross-section? A. Paleocene sandstone is older than Basaltic dike. B. The fossil formed before 125 Ma. C. After the formation of limestone layer, the environment changed to a depositional one. D. Limestone layer is older than 80 Ma. ** Refer to the following figure to answer the following questions (12 – 15) 12. What principle tells us about the relative ages of Formations B through D?  Superposition 13. What principle tells us about the relative ages of Formations E and Granite Pluton?  Cross-cutting 14. What principle tells us about the relative ages of Formations K and Granite Pluton?  Intrusion 15. What is the correct description for X?  Pg. 309 Sill 16. What is the two most important aspects by which fossils can be used to decipher the past history of the Earth? A. Time marker, and dating the first time the crust formed. B. Dating the first time the crust formed, and indicator to the past depositional environments. C. Time marker, and indicator to the past depositional environments. D. Indicator to the past depositional environments, independent indicator to the absolute age without any previous known knowledge. 17. What is an index fossil?  Time marker. Used to determine time period. 18. What is the name of the following site pictured, and what type of unconformity can you observe here? What geologic era did it form in?  Siccar Point, in Scotland.  Angular Unconformity  Devonian 19. What geologic feature would be formed from the process found on the following figure?  Angular Unconformity 20. What geologic feature would be formed from the process found on the following figure?  Nonconformity 21. What geologic feature would be formed from the process found on the following figure?  Disconformity 22. The following figure depicts the vertical cross-section of National Parks of Arizona and Utah. In what location would you expect to find an outcrop that shows the oldest geologic time? (Assume the principle of superposition)  Grand Canyon ** Refer to the following. On the left, depicts a depositional environment in which rock columns A, B, & C formed, which can be found form the figure on the right. 23. What is the process that geologists try to find common in beds A, B, & C, and compare to the formation of rock columns.  Stratigraphic Correlation 24. What are two commons ways geologists figure out stratigraphic correlation?  Fossil, Lithologic 25. Who made the first geologic map?  William Smith 26. What is the largest subdivision of geologic time?  Eon (Eon Era Period  Epoch) 27. What eon stands for “Visible Life”? “Hell”? “Before life”? Referring to the previously listed, what are their numerical time periods?  Phanerozoic: 542 million years ago – Today  Hadeon: 4.6 – 4.1 billion years ago  Protozoic: 2,500 – 542 million years ago 28. What era contains the time of “Cambrien Explosion”?  Paleozoic ** The figure below describes the history of life throughout the history of the Earth. Questions #29 - 31 29. What time period witnessed “Oxygen Revolution”?  Phanerozoic (witnessed the Cambrien Explosion) 30. In what time period did multicellular life evolve?  Proterozoic 31. What is the correct explanation about the geologic time and the evolution of life? A. Cenozoic is the era of dinosaurs. B. Dragonflies got extinct before Mesozoic Era. C. Plants landed before the animals did. D. Life started on the land from the very beginning. 32. What is the area of geology that studies numerical ages of geologic features?  Absolute Age Dating 33. **Same as Question # 32. 34. What is the correct explanation about the radioactive decay, and the present and the daughter isotopes? A. The daughter isotope is unstable and decay to produce the parent isotope. B. The amount of the parent isotope decreases as time goes by. C. The parent isotope is the product of the decay of the daughter isotope. D. If the decay creates new unstable elements, then the decay stops. 35. What is the half-life?  The time in which a parent isotope decays. 36. The following figure depicts the radioactive decay process from Time 1 through Time 5. What is the formula that calculates the half-life of the parent isotope? A. (Time 2 – Time 1) B. (Time 5 – Time 1) C. Time 3 D. (Time 2 – Time 1) / 2 37. Which on the following is the correct explanation for closure temperature for isotopic dating? A. It is the melting temperature of mafic minerals. B. Isotopic dating gives the time a mineral cooled below that temperature. C. A metamorphic rock cannot be dated by radioactive isotopes because it never reached that temperature. D. Sedimentary rocks are the best rock type to be dated by radioactive isotopes. 38. **Same as Question #3 39. Which one of the following cannot be used for numerical age dating? A. Growth rings of trees. B. Annual layers indicating the growth of shells. C. Radioactive dating. D. Succession of fossils of which absolute ages are not determined yet. 40. Where did the Devonian Period get its name?  The first distinguishing rocks were studied in Devon, England. 41. Why did the Carboniferous Period from Paleozoic Era have that name?  Lots of Carbon
