Which are the three types of wind erosion?

• A. Creep, Abrasion, Erosion
• B. Creep, Saltation, Erosion
• C. Saltation, Suspension, Deflation
• D. Creep, Saltation, Suspension

Answer: (D)

Wind erosion happens when air moves soil particles in distinct ways, and there are three primary modes of particle movement. The first is creep, where larger particles roll or slide along the surface, often pushed by the impact of smaller grains. The second is saltation, where mid-sized grains are lifted briefly, hop a short distance, and then land, causing further ejecta on each impact. The third is suspension, where the finest particles are lifted high into the air and carried away for long distances. These three modes capture how wind actually moves soil particles. Other options blend in erosion as a general outcome or introduce deflation, which is a broader term for removal of loose material, rather than a specific mode of wind-driven particle transport. Hence, creep, saltation, and suspension form the correct trio.
