Water-erosion can be reduced / controlled by:___________?
Correct answer: C. Both a & b
- A. Provision of surface-cover that intercepts the rain before hitting the soil.
- B. Reducing the amount of runoff by promoting infiltration.
- C. Both a & b
- D. None of the aboveSoil
Explanation
Surface cover intercepts raindrops and protects soil aggregates, while improved infiltration reduces the volume of runoff available to cause erosion. Both mechanisms therefore control water erosion.
