plate tectonics
Across
- 4. most destruction during an earthquake
- 6. the plates start shaking
- 7. pressing something into a smaller space or putting pressure on it from different sides until it gets smaller
- 11. second wave of an earthquake
- 13. the act of stretching or the state or degree of being stretched stress
- 14. vertical fractures where the blocks have mostly moved horizontally
- 16. recording of the ground shaking at the specific location of the instrument
- 18. move on the crust
- 19. first wave of an earthquake
- 20. magma reaching the surface
Down
- 1. great size of something
- 2. past each other
- 3. the force on earth changing its shape
- 5. evidence of pangea
- 8. ground shaking and damage
- 9. fault the block above the fault moves up relative to the block below the fault
- 10. above the epicenter
- 12. where an earthquake begins underground
- 15. fault block above the fault has moved downward relative to the block below
- 17. crack in the earth
