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