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

where does ocean crust go

Where Does Ocean Crust Go?

Hugo Benioff, 1954

plate boundaries
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
