Across
- 3. - a string of volcanoes around the Pacific Ocean/Plate
- 7. - vents(openings) in the Earth’s crust through which molten rock flows
- 8. - a break in the Earth’ surface, in which rocks may move, causing earthquakes
- 9. - the location on the Earth’s surface, directly above the focus
- 10. - the place where two tectonic plates meet
- 13. - new crust forms from cooling lava along the mid-ocean ridge and pushes older crust away from the middle.
- 14. - slower earthquake waves that move in an “up-down” motion and travel only through solids. (causes more damage)
- 17. - the theory that the continents slowly moved across the surface of the Earth.
- 19. - a machine used to detect earthquake waves
- 20. - a huge piece of the crust (rock) that moves because of convection currents.
Down
- 1. - a large ocean wave often caused by an earthquake in/near the ocean
- 2. - a large mountain range below the ocean-bigger than any on land
- 4. - the point underground where the earthquake begins
- 5. - the rising, spreading and sinking of molten material, in a circular motion in the mantle, which causes the plates to move
- 6. - the theory that the Earth’s surface is made of hard slabs of rock, or plates, that move with respect to each other.
- 11. - the fastest earthquake wave, that moves in a “push-pull” motion and travels through solids, liquids & gasses
- 12. - one large continent, with all the land connected together
- 15. - vibrations in the ground that happen because of plates moving/faults
- 16. - areas in the middle of a plate where molten rock escapes from the mantle
- 18. - energy from an earthquake that travels as vibrations
