Across
- 1. The underground origin of an earthquake.
- 5. The pulling and or stretching of rock at a divergent boundary.
- 9. Instrument used by geologists to track the speed of seismic waves.
- 13. Type of boundary where plates are moving apart from each other.
- 14. The above ground origin of an earthquake.
- 15. The squeezing of rock at a convergent plate boundary.
- 17. Surface wave and most destructive they move in a rolling motion.
Down
- 1. Occurs as a break in the Earth’s brittle crust.
- 2. Shearing takes place at this type of fault associated with transform boundaries.
- 3. The cause for rock folding and the formation of faults.
- 4. Type of boundary where plates are pushed toward each other.
- 6. Wave that can only move through solids and may cause moderate damage.
- 7. This can occur deep in the crust where temperatures are high due to stress.
- 8. A type of fault where tension causes the hanging wall to move down.
- 10. The result of stress in the Earth’s crust.
- 11. Type of boundary where plates move along side each other.
- 12. A type of fault where compression forces the hanging wall to move up.
- 16. Fastest of the seismic waves and can travel through liquid, solid, or gas.
