Alfred Wegener b. H. B. Baker c. Charles Darwin d. Arthur Holmes e. Harry Hess 7. The scientific community rejected the theory of continental drift because Alfred Wegener could NOT ________________. a. identify a mechanism to move the continents b. disprove competing theories that were not accepted by scientists c. find geologic similarities on the different continents d. all of the above e. None of the above 8. In the 1950s, Harry Hess interpreted this paleomagnetic data of newly formed oceanic crust. He proposed that while new oceanic crust was being formed at the summit of the oceanic ridges, the adjacent oceanic crust was moving laterally away from the ridge. What is this process called? a. Deep-sea trench b. Ocean crust c. Seafloor spreading d. Hot spots e. None of the above 9. With the advent of plate tectonics, it was discovered that new oceanic lithosphere is being created at what location? a. Seafloor spreading b. Deep-sea trenches c. Oceanic ridges d. Continental crust e. Lithosphere Questions 10–14 are based on the online video Historical Development of Plate Tectonics Theory. You need to watch the entire segment in the online activity to answer all of the questions. 10.

Palm b. Fern c. Redwood tree d. Maple tree e. All of the above 11. In the early 1800s, geologist Eduard Suess suggested that all the southern continents, including Antarctica, had once been joined into one large continent. What name did Suess call the one continent? a. Pangaea b. Megacontinent c. Gondwanaland d. Laurasia e. None of the above 12.
