Question

Tree windbreaks protect soil-carrying capacity of wind for approximately —————— times the height of the tall tree on the windward side.

• A. 3-4
• B. 15-20
• C. 5-10
• D. 11-15

Hint:

Windbreaks reduce wind speed over an area 5-10 times their height.

Answer 1

The Correct Option is C

Step 1: Understanding Windbreak Effectiveness
Windbreaks reduce wind speed and prevent soil erosion.
Step 2: Evaluating Distance Protected
Windbreaks protect an area about 5-10 times their height.
Step 3: Conclusion
Thus, the correct answer is 5-10 times tree height.
