Which action often accelerates erosion?

• A. Rain
• B. Roots
• C. Removal of plants
• D. Wind

Answer: (C)

Plants protect soil from erosion by slowing rainfall impact, increasing water infiltration, and anchoring soil with their roots. When plants are removed, the soil is exposed and lacks that protection. Raindrops hit bare soil with more energy, breaking up particles and creating runoff that can carry soil away. Without roots to hold the soil together, its structure becomes weaker and more easily moved downslope. Wind can also pick up exposed topsoil more readily when there’s no plant cover. So removing plants often accelerates erosion because it removes both the protective shield and the binding that keep soil in place.
