Question

Given below are two statements
Statement I: A high‐density shelterbelt will provide a higher level of shelter over a shorter distance than a medium or low‐density belt.
Statement II: Orientation of windbreaks should be parallel to the prevailing wind
In light of the above statements, choose the correct answer from the options given below

• A. Both Statement I and Statement II are true
• B. Both Statement I and Statement II are false
• C. Statement I is true but Statement II is false
• D. Statement I is false but Statement II is true

Hint:

Shelterbelt Orientation Rule: Always plant Perpendicular (90$^\circ$) to the hot/dry winds. If the wind comes from the West, your tree line should run North-South.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question again examines the mechanics of windbreaks and shelterbelts, focusing on density and orientation.
Detailed Explanation:

• Statement I analysis: As explained in the previous question, an impermeable (high-density) belt causes high turbulence and rapid wind recovery, providing an intense but short distance of protection. Statement I is True.

• Statement II analysis: The purpose of a windbreak is to "break" or obstruct the wind. To do this effectively, the belt must be oriented perpendicular (at a right angle) to the prevailing wind. If the orientation is "parallel," the wind will simply blow alongside the belt without being slowed down, rendering the windbreak useless. Therefore, Statement II is False.

Step 2: Final Answer:
Statement I is correct, and Statement II is incorrect.
