Plate Tectonics

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

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
