Question

The correct order of movement of soil particles during wind erosion is

• A. Surface creep, Saltation, Suspension
• B. Saltation, Surface creep, Suspension
• C. Suspension, Surface creep, Saltation
• D. Saltation, Suspension, Surface creep

Hint:

Wind erosion modes:
- Surface creep: Rolling particles.
- Saltation: Bouncing particles.
- Suspension: Airborne particles.

Answer 1

The Correct Option is A

Step 1: Understanding the Question:
This question tests knowledge of the modes of soil movement during wind erosion.

Step 2: Detailed Explanation:
The correct order of movement of soil particles during wind erosion is:
1. Surface creep: Large particles (0.5-1.0 mm) roll along the ground.
2. Saltation: Medium particles (0.1-0.5 mm) bounce and jump.
3. Suspension: Fine particles (< 0.1 mm) are carried in the air.
Thus, the order is Surface creep, Saltation, Suspension.

Step 3: Final Answer:
Thus, the correct order is Surface creep, Saltation, Suspension, which corresponds to option (A).
