After referring to the section titled The Nature of Scientific Inquiry, in Chapter 1 complete the following: a. What observation led Alfred Wegener to develop his continental drift hypothesis? b. What evidence did he gather to support his proposal? c. Why was the continental drift hypothesis rejected

. Referring to the accompanying diagrams that illustrate the three types of convergent plate boundaries, complete the following: a. Identify each type of convergent boundary. b. Volcanic island arcs develop on what type of crust? c. Why are volcanoes largely absent where two continental blocks collid

Some predict that California will eventually sink into the ocean. Is this idea consistent with the theory of plate tectonics? Explain.

. Referring to the accompanying hypothetical plate map, complete the following: a. Portions of how many plates are shown? b. Is continent C moving toward or away from continents A and B? How did you determine your answer? c. Explain why active volcanoes are found on continent A and continent B. d. Wh

Volcanoes that form over mantle plumes such as the Hawaiian chain are some of the largest on Earth. However, several volcanoes on Mars are gigantic compared to those on Earth. What does this difference tell us about how, or if, plate tectonics operates on Mars? Explain.

Imagine you are studying seafloor spreading along two different oceanic ridges. Along the first ridge the magnetic stripes are uniformly narrow. Along the second ridge they are wide near the ridge crest, but they become narrower as you move away from the crest. What can you say about the history of m

Australian marsupials (kangaroos, koala bears, etc.) have direct fossil links to marsupial opossums found in the Americas. Yet the modern marsupials in Australia are markedly different from their American relatives. How does the breakup of Pangaea help to explain these differences (see Figure 7.A)?

Earth Science 13
During the breakup of Pangaea, which continent was actually growing in size through the accumulation of other landmasses? (see Figure 7.A)

Density is a key component in the behavior of Earth materials and is especially important in understanding key aspects of plate tectonics. Describe three ways that density and/or density differences play a role in plate tectonics.

Refer to the accompanying map to complete the following: a. List the cities (in pairs) that are moving farther apart as a result of plate motion. b. List the cities (in pairs) that are moving closer together as a result of plate motion. c. List the cities (in pairs) that are presently not moving rela
