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.
Where is mass wasting most likely to occur?
Applacian mountains
A corn field
The beach
Everglades swamp
