Across
  1. 4. a surface feature in the seafloor produced by the descending plate during subduction
  2. 6. a fault in which the rock above the fault plane has moved down relative to the rock below
  3. 7. the process by which plate tectonics produces new oceanic lithosphere at ocean ridges
  4. 9. a boundary in which two plates move together
Down
  1. 1. a boundary where the rigid plates are moving apart, typified by the oceanic ridges
  2. 2. a continuous elevated zone on the floor of all the major ocean basins and varying in width from 1000-4000 kilometers
  3. 3. a boundary in which two plates slide past each other without creating or destroying lithosphere
  4. 5. deep faulted structure found along the axes of divergent plate boundaries
  5. 8. a destructive plate margin where oceanic crust is being pushed down into the mantle beneath a second plate
