Windbreaks are intended to achieve what primary effect?

• A. Increase crop density
• B. Reduce wind erosion
• C. Filter pesticides
• D. Provide shade

Answer: (B)

Windbreaks slow the wind near the soil surface, which lowers the force that can lift and transport soil particles. By reducing wind speed, they significantly cut wind erosion, helping keep the topsoil in place, protect seedlings, and conserve soil moisture. While windbreaks can offer extra benefits like some shading or microclimate changes, their primary purpose is soil conservation by reducing wind erosion. The other options don’t align with the main function: increasing crop density isn’t achieved by a barrier, shading isn’t the primary goal, and filtering pesticides is not the main purpose of windbreaks.
