A Correct answer
Explanation

Lack of vegetation is a major cause of soil erosion because plant roots hold soil in place and prevent water and wind from carrying it away. Areas with excess vegetation actually have less erosion, while rocks don't directly cause erosion and less rainfall means less water erosion.
