Across
- 1. This consists of mountain chains, with a rift valley running along its spine, formed by plate tectonics
- 5. where crust is destroyed as one plate dives under another
- 7. a scientific theory that explains how major
- 9. Is a shallow part of the ocean nearly near the upper
- 12. in position and direction
- 13. a long narrow hilltop, mountain range, or watershed
- 15. where crust is neither produced nor destroyed as the plates slide horizontally past each other
- 16. its an displacement in the earth crust
- 18. a series of mountains or mountain ridges
- 20. where molten lava hot ash and gases from below the Earth's crust escape into the air
Down
- 2. The impact of the colliding plates can cause the edges of one or both plates to buckle up into a mountain ranges or one of the plates may bend down into a deep seafloor trench
- 3. a seafloor mountain system formed by plate tectonics
- 4. Its nearly above the water near the surface
- 6. the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth
- 8. movements
- 10. Goes downward and sideward of the edge edge of a plate of the earth's crust into the mantle beneath the ocean
- 11. Consists of an upper mantle and an crust
- 14. Is a crust that is under the ocean
- 17. are created as a result of Earth's
- 19. Is a really shallow part an can only occur an Low
