Which soil‑conservation technique is most suitable for preventing erosion on steep slopes of the Western Ghats?

hard MCQ 2 marks Class 10 · Geography · Resources and Development
  1. Contour bunding
  2. Terracing
  3. Strip cropping
  4. Windbreaks
Answer
Terracing

The correct answer is Terracing — Hence, the correct answer is Terracing.

Step-by-step solution

  1. Identify the main problem: high‑gradient slopes cause rapid runoff and sheet erosion.
  2. Review each technique:
  3. – Contour bunding creates low earthen barriers along contour lines; effective on gentle to moderate slopes.
  4. – Terracing transforms steep slopes into a series of flat steps, greatly reducing runoff velocity.
  5. – Strip cropping separates crops with different root structures; mainly for gentle slopes.
  6. – Windbreaks protect against wind erosion, not water erosion on slopes.
  7. Select the method that directly reduces slope length and runoff speed on steep terrain, which is terracing.
  8. Hence, the correct answer is Terracing.
Common mistake: Choosing contour bunding, which is better for gentle slopes

Concept tested: Soil conservation on steep slopes
