Frank Taylor
• Recognized role of Mid-Atlantic Ridge
• Never reconstructed the continents like Wegener did

Confirmation of Continental Drift
• World War II technology
• International Geophysical Year (IGY) 1957-58

Plate Boundaries
• Divergent– Can create volcanoes, earthquakes, and mountains– Examples: Mid-Atlantic ridge, East Pacific Rise
• Convergent– Can create volcanoes (continental and island arc),
earthquakes, and mountains– Examples: Juan De Fuca Plate and North America Plate
• Transform– Can create strong shallow earthquakes and folded
mountains– Examples: San Andreas Fault
