Plate Tectonics By:Emy Turner
Across
- 1. an opening in a planet or moon's crust
- 8. chamber a large pool of liquid rock beneath the surface
- 9. often ejected with great force, can travel significant distances from the volcano before solidifying
- 10. Propagation of mechanical energy through the earth's layers
- 12. any sudden shaking of the ground
Down
- 2. the passage way that magma travels to reach the surface
- 3. a hard, dark, glass like volcanic rock
- 4. A flat piece of rock formed when magma hardens in a crack in a volcano
- 5. funnel-shaped depression that usually lies directly above the vent\
- 6. the movement of a mass of rock, debris, or earth down a slope
- 7. The geographic location and depth where the earthquake starts
- 9. the place at the Earth's surface where lava flows
- 11. Line along which two sections of rock can move against each other
