- 9. masses of soil and fragmented rock rush down mountainsides
- 10. a steep (nearly vertical) region of exposed soil and rock at the head of the landslide where the failure surface ruptures the ground surface
- 11. slow downslope movement of material under gravity
- 13. scattered pieces of rubbish or remains
- 14. being gradually damaged and removed by the waves, rain, or wind:
- 15. the processes by which rock is broken into smaller pieces by the action of the weather

- 3. when loosely packed, water-logged sediments at or near the ground surface lose their strength in response to strong ground shaking
- 5. flow of water that contains large amounts of suspended particles and silt
- 6. the steepest angle of descent or dip relative to the horizontal plane to which the material can be piled without slumping
