Across
- 3. Caused by forces that are exerted on the edges or interior of a material
- 7. Regions that are below sea level
- 10. Form when the hanging wall moves up
- 11. Support the theory of Sea-Floorspreading
- 13. Youngest strata in center
- 14. Occures when hanging wall moves down relative to the foot wall
- 15. A central valley formed at the summit of the oceanic ridges
- 17. Proposed that the sea-floor is spreading
- 18. Break in the Earth's crust
- 19. A geological features formed by convergent boundaries
Down
- 1. Internal process drives the molten rocks in the mantle
- 2. Measurements of ocean depths and the charting of the shape or topography of the ocean floor
- 3. A geological process in which tectonic plates-large slabs of Earth's lithosphere split apart from each other
- 4. Kind of plate boundary occurs in sea-floor spreading
- 5. Continental crust transition into oceanic crust
- 6. A fracture or zone of fracture between two blocks of rock
- 8. Oldest strata in center
- 9. The process by which heat from the earth's interior causes magma to rise and sink
- 12. Older and colder plates sink at subduction zones
- 16. A transform boundary connects two diverging boundaries
