Kennady Bollenbacher D 1-3 review
Across
- 3. the point on Earth's surface directly above the focus of an earthquake
- 5. spot A very hot part of the Earth's mantle, where magma can melt through a plate moving above it
- 8. Earth's solid, rocky surface containing the continents
- 9. A sensitive device that detects the shaking of Earth's crust during an earthquake
- 13. A wide, gently sloped cone that forms from flows of lava
- 14. The idea that new crust is forming at the ridges in the sea floor, spreading apart the crust on either side of the ridges
- 16. A steep sided cone that forms from explosive eruptions of hot rocks, ranging from particles to boulders
- 18. Magma that reaches Earth's surface and flows out a vent
- 20. The amount of energy released by an earthquake
- 21. energy heat from earth's surface
- 22. A huge crack in Earth's crust at or below the surface, the sides of which may show evidence of motions
Down
- 1. shaking off Earth's crust after the initial shaking of an earthquake
- 2. The idea that Earth's surface is broken into plates that slide slowly across the mantle
- 4. A cuplike hollow that forms at the top of a volcano around the vent
- 6. The idea that many kinds of rocks form flat, horizontal layers
- 7. wave A vibration that spreads out away from a focus when an earthquake happens
- 8. drift The idea that a supercontinent split apart into pieces, the continents which drifted in time to their present location
- 10. The point where an earthquake starts as rocks begin to slide past each other
- 11. Hot, molten rock below Earth's surface
- 12. The layer beneath Earth's crust
- 15. A cone formed from explosive eruptions of hot rocks followed by flows of lava, over and over
- 17. the sliding of a denser ocean plate under another plate when they collide
- 19. The central opening in a volcanic area through which magma may escape
