Question

Highest wind erosion has occurs in

• A. East India
• B. West India
• C. North India
• D. South India

Hint:

Arid Rajasthan and western Gujarat (West India) are the hotbeds for wind erosion in India due to dry sandy soils, sparse vegetation, and high summer wind speeds.

Answer 1

The Correct Option is B

Step 1: Understanding the Concept:
Wind erosion occurs primarily in regions characterized by low and erratic rainfall, high temperatures, high wind velocities, low relative humidity, and sparse vegetative cover.
These conditions facilitate the drying, detachment, and transport of loose, sandy soil particles by wind.

Step 2: Detailed Explanation:
In India, wind erosion is a major land degradation process in the arid and semi-arid tracts.
The hyper-arid and arid regions of West India (specifically the Thar Desert region of Rajasthan, along with parts of Haryana, Punjab, and western Gujarat) experience the highest wind erosion.
This region is characterized by:
1. Loose, single-grained sandy soils that are highly susceptible to wind detachment.
2. Very low vegetative cover to shield the soil or act as windbreaks.
3. High-velocity winds during the summer months (May to July) that drive soil movement through saltation, suspension, and surface creep.
In contrast, East and South India receive higher or more distributed rainfall, leading to higher clay content and denser vegetative cover that prevents major wind erosion.

Step 3: Final Answer:
The highest wind erosion in India occurs in West India, which corresponds to option (B).
