Question

Given below are two statements:
Statement (I): Shelter belts are strips of trees/shrubs planted to protect the agricultural fields, homes from wind and blowing sand.
Statement (II): Wind breaks are blocks consisting of several rows of trees established at right angles to the prevailing wind direction.
In light of the above statements, choose the most appropriate answer from the options given below:

• A. Both Statement (I) and Statement (II) are correct.
• B. Both Statement (I) and Statement (II) are incorrect.
• C. Statement (I) is correct but Statement (II) is incorrect.
• D. Statement (I) is incorrect but Statement (II) is correct.

Hint:

To distinguish between the two:
- Windbreak = A rrow barrier (usually 1 to 3 rows of trees).
- Shelterbelt = A wide belt of trees and shrubs (typically 5 or more rows) covering a larger area.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
Shelterbelts and windbreaks are protective barriers of trees and shrubs designed to reduce wind speed, control wind erosion, and protect crops, soil, and structures.
While similar in purpose, they differ in their scale, width, and structural composition.

Step 2: Detailed Explation:
Let us evaluate both statements based on forestry engineering definitions:
• Statement (I): Shelterbelts are indeed wide belts or strips of trees and shrubs planted to protect agricultural fields, highways, and habitations from strong winds and blowing sand. This statement is correct.

• Statement (II): Windbreaks are defined as barriers of trees or shrubs, usually consisting of only one to three rows, designed to reduce wind speed over a localized area. In contrast, "blocks consisting of several rows of trees" actually describes the structure of shelterbelts, which are wider and more complex. Therefore, the definition of windbreaks in Statement II is incorrect.
Thus, Statement I is correct, but Statement II is incorrect.

Step 3: Fil Answer:
The correct option is (C).
