Plate Tectonics
Across
- 2. a giant ocean wave that forms after a volcanic eruption, submarine earthquake, or landslide
- 5. a large landmass that was made up of continents
- 6. the location within earth along a fault at which the first motion of an earthquake occurs
- 8. a measure of the strength of an earthquake
- 10. the sudden return of elastically-deformed rock to its undeformed shape
- 12. the theory about how plates changed position over time
- 13. the plastic-like layer of Earth's surface where continental plates move
- 16. an area along a fault where relatively few earthquakes have occurred recently but where strong earthquakes have occurred in the past
- 18. a movement of trembling of the ground that is caused by a sudden release of energy when rocks along the fault move
- 19. in Earth science, the amount of damage caused by an earthquake
Down
- 1. the crust and part of the upper mantle
- 3. a wave of energy that travels through the earth and away from an earthquake in all directions
- 4. a break in a body of rock along which one block slides relative to another
- 5. sections of Earth's crust and part of the upper mantle
- 7. scientist who created the Continental Drift theory
- 9. the process that occurs at mid-ocean ridges (new oceanic crust is created through volcanic activity, and slowly moves away from the ridge)
- 11. the bending of rock layers due to stress
- 14. the process where one plate sinks below the other
- 15. the point on Earth's surface directly above an earthquake's starting point, or focus
- 17. the [blank] scale is one of the ways you can find an earthquake's magnitude
