Across
- 3. Long narrow mountains formed by magma at divergent boundaries
- 7. Two plates move toward each other
- 10. Vents in earth's crust through which molten rock flows
- 12. Blocks of crust that move horizontally past each other
- 13. The partially melted portion of the mantle
- 15. The size of an earthquake
- 16. rising mantle material at mid-ocean ridges push plates away from the ridge
- 17. Earth is broken down into large rigid pieces that move with respect to each other
- 18. This rock is formed by erosion
- 20. Two plates collide, one can sink other the other, when this happens it pulls on the rest of the plate
Down
- 1. The process that occurs when one tectonic plate moves under another tectonic plate
- 2. The crust and uppermost part of the mantle
- 4. This rock is formed by heat and pressure
- 5. The circulation within fluids caused by differences in density and thermal energy
- 6. Two plates move away from each other
- 8. Magma that erupts onto earth's surface
- 9. Molten rock stored beneath earth's surface
- 11. A crack or fracture in earth's crust along which movement occurs
- 14. A vibration caused by the rupture and sudden movement of rocks along a crack in earth's crust
- 19. This rock is formed when hot molten rock crystallizes
