Plate Tectonics
Across
- 4. Magma that erupts onto the earth's surface.
- 7. Molten rock stored beneath the earth's surface.
- 8. A boundary where two plates move toward each other.
- 9. rising mantel material at mid-ocean ridges push plates away from the ridge.
- 10. the size of an earthquake is determined by how much energy is released by an earthquake.
- 14. Vents in the earth's crust through which molten rock flows.
- 15. Lave that erupts underwater that hardens and flows into unique shapes.
- 18. made up of one or more faults.
- 19. features that cross the fault such as streams shifted both by plate movement and earthquakes.
- 20. the circulation within fluids caused by differences in density and thermal energy.
Down
- 1. Formed similarly to the Himalayas.
- 2. long narrow mountains formed by magma at divergent boundaries.
- 3. when two plates slide past each other.
- 5. the vibrations caused by rupture in the sudden movement of rocks along a break or a crack in earths crust.
- 6. A boundary when two plates move away from each other.
- 11. largest and highest mountain range in the world that are still growing.
- 12. section of the earth combining the crust and upper mantle.
- 13. when two plates collide, one can sink the other when this happens, it pulls on the rest of the plate.
- 16. a crack or fracture in the earth's crust along which movement occurs.
- 17. The process that occurs when one tectonic plate moves under another tectonic plate.
