Across
- 2. deformation of material in response to stress
- 4. Earth's surface directly above the focus
- 7. waves are much slower & does more destruction
- 9. a fracture or a weak zone between rocks.
- 11. compression movement & vertical
- 12. force acting on crustal rock
Down
- 1. decreases the volume of a material
- 2. waves slower than primary
- 3. tension and downward
- 5. pulls the material apart
- 6. waves straightens when pulled like a coil wire
- 7. horizontal movement in opposite directions
- 8. point of failure where the waves originate
- 10. causes the material to twist
