Across
- 1. This type of stress stretches rock.
- 3. This scale measures the magnitude based on the size of the seismic waves.
- 5. These carry energy from an earthquake, away from the focus, through Earth’s interior, and across the surface.
- 6. This stress can cause rocks to slip.
- 10. A violent movement caused by shifting of plate boundaries.
- 11. What stress pushes rock together.
- 13. This wave vibrates the ground side to side, as well up and down. It’s also called the secondary wave.
- 14. A rift valley forms along this boundary.
- 18. This wave makes the ground surface roll with a wavelike motion.
- 19. This scale measures the damage of the earthquake.
Down
- 2. This is recording on paper of the shaking motion of the earthquake.
- 4. In this fault the hanging wall moves up the footwall.
- 6. The study of earthquakes.
- 7. This fault has the hanging wall slip down relative to the footwall.
- 8. What boundary makes two continental plates collide forming a mountain range?
- 9. An instrument that records seismic waves.
- 12. What fault has rocks on either side that slip past each other?
- 15. This boundary has to plates that slide past each other.
- 16. When all the the continents were one land mass.
- 17. This seismic wave compresses and expands the ground like an accordion.
