Final answer:
The mountain model supports preserving vegetation to prevent soil erosion.
Explanation:
The mountain model supports the idea of preserving vegetation in areas affected by high erosion as vegetation plays a crucial role in preventing soil erosion on mountainsides. Plants help stabilize the soil, reducing the risk of landslides and erosion caused by water runoff. For example, the roots of trees and other plants bind the soil together, preventing it from being washed away by rainwater.
