(from geology.com)
Answers can be found on corresponding pages of text book (Foundations of Earth Science, Lutgens,
Tarbuck, Tasa 6e) Note that questions are continued on page 2.
1. Discuss the evidence that Alfred Wegener used to support his continental drift
hypothesis. (p. 143 – 146)
2. What was Pangaea? (p. 143)
3. What were the main objections to the continental drift hypothesis? (p. 147)
4. Which discoveries, in the latter half of the 20th century, led directly to the development
of the plate tectonics theory? (p. 147)
5. Explain the difference between the lithosphere and the asthenosphere? What is the role
of each in the plate tectonics model? (p. 148 - 149)
6. What are the three major types of plate boundaries? Describe the relative motion of
each. (p. 150)
7. What is seafloor spreading? With which type of plate boundary is seafloor spreading
associated? Where is active sea floor spreading occurring today? (p. 151)
8. Give an example of a divergent plate boundary in an ocean and a divergent plate
boundary on a continent. (p. 151 - 152)

9. Name a body of water that may be a future ocean basin. (p. 152)
10. What are subduction zones and with which types of convergent boundaries are they
associated? (p. 152 – 153)
11. Which features are associated with both oceanic – continental and oceanic – oceanic
convergent plate boundaries? Name a specific example of each. (p. 153 – 155)
12. Describe how the Himalaya Mountains formed. Name three other mountain ranges that
formed this way. (p. 155 – 156)
13. Where are most transform boundaries located? (p. 156) What are some functions of
transform faults in these locations? (p. 157)
14. How do transform faults differ from divergent and convergent boundaries? (p. 156 –
158).
15. Name the well known transform fault in California. (p. 158)
16. With which of the three types of plate boundaries are the following locations
associated? Aleutian Islands, Andes Mountains, Red Sea, Cascade Mountains, Iceland,
San Andreas Fault. (Chapter 5)
17. Discuss three types of evidence supporting the plate tectonics theory. (p. 159 – 162)
18. How do hot spots and the plate tectonics theory account for the fact that the Hawaiian
Islands vary in age? (p. 159 – 161)
19. Define paleomagnetism and explain why it is the most persuasive evidence for the plate
tectonics theory. (p. 160 – 164)
