Why is planting trees on a muddy slope a good idea to prevent mudflows and landslides?
The tree roots soak up water
The roots of trees keep the soil in place
Trees add homes for wildlife
Just a and b
- 19. Multiple Choice
Why is decreased vegetation a factor that can cause mass wasting?
When plants are removed from the ground, the spaces they leave are filled with heavier rocks.
Decreased vegetation is not a factor that causes mass wasting.
Vegetation stabilizes soil at the surface, and their roots anchor soil under the surface.
Decreased vegetation is not a factor that causes mass wasting.
- 20. Multiple Choice

Applacian mountains
A corn field
The beach
Everglades swamp
- 21. Multiple Choice

- 24. Multiple Choice
What always plays the main role in a landslide, regardless of the cause?
Mud
Wind
Gravity
Earthquakes
- 25. Multiple Choice
Why do so many landslides occur near mountains, rather than in flat areas?
