  • Recognized role of Mid-Atlantic Ridge

  • Never reconstructed the continents like Wegener did


Confirmation of continental drift
Confirmation of Continental Drift

  • World War II technology

  • International Geophysical Year (IGY) 1957-58

  • Worldwide Standardized Seismic Network 1963-





Where does ocean crust go

Where Does Ocean Crust Go? Experiment

Hugo Benioff, 1954










How plates move
How Plates Move Experiment








Plate boundaries
Plate Boundaries Experiment

  • 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
