Size range of soil particles in saltation type of wind erosion is:

Correct option is C

The correct answer is (C) 0.05–0.5 mm

Explanation:
• Wind erosion occurs through three distinct processes based on particle size: saltation, surface creep, and suspension.
• Saltation is the most significant process, accounting for 50% to 75% of total soil movement by wind.
• It involves medium-sized soil particles, typically in the range of 0.05 to 0.5 mm in diameter.
• These particles are lifted by wind and then bounce along the soil surface. When they strike the ground, they break down soil aggregates and dislodge other particles, further accelerating the erosion process.

Information Booster:
• The height to which particles rise in saltation depends on their size and wind velocity, but most movement occurs within 30 cm of the ground.
• Saltation is considered the "key" to wind erosion because it triggers both suspension and surface creep.

Additional Knowledge:
• Surface Creep (Option B): Involves larger particles (0.5 to 2.0 mm) that are too heavy to be lifted; they roll or slide along the surface.
• Suspension (Option D): Involves very fine particles (less than 0.1 mm, often specifically 0.002–0.05 mm) that are kicked up by saltation and carried high into the atmosphere over long distances.
• Clay and Silt (Option D): These particles are usually less than 0.05 mm and are the primary components of dust storms.
