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