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