Correct option is B
The correct answer is (B) Saltation, surface creep, suspension
Explanation:
• Wind erosion occurs in three distinct processes depending on the size of the soil particles.
• Saltation: Accounts for the bulk of wind erosion ($50-75\%$). It involves medium-sized particles (0.1 - 0.5 mm) that are lifted a short distance into the air and then fall back, bouncing along the surface.
• Surface Creep: Involves larger particles (0.5 - 2.0 mm) that are too heavy to be lifted. They are rolled or pushed along the surface by the impact of particles in saltation.
• Suspension: Involves very fine particles (less than 0.1 mm) that are lifted high into the atmosphere and can be carried thousands of miles. This forms "dust storms."
• The order in terms of the quantity of soil moved is typically Saltation $>$ Surface Creep $>$ Suspension.
Information Booster:
• Saltation is the key process; without it, surface creep would hardly occur.
• Shelterbelts (rows of trees) are effective because they reduce wind velocity below the threshold required to initiate saltation.
• This classification was famously detailed by W.S. Chepil in the mid-20th century.
Additional Knowledge:
• Option A: While these are the three processes, Saltation is usually listed first as it is the most significant in terms of mass transport.
• Suspension: While visually dramatic, it actually moves the least amount of total soil mass compared to saltation.
