12.1 How does continental drift relate to plate tectonics?

• Alfred Wegener - advocated matching continental boundaries by shape and geologic features (1912, 1928). Hypothesized idea of continental drift—that continents move over geologic time.
• Good data on fitting continents together
• However, no good mechanism for movement
• Posited them moving like icebreakers through the oceanic crust
• Idea dismissed by most of the geologic community
