Wind contributes to weathering by which mechanism?

Explanation:
Wind contributes to weathering mainly through abrasion. When wind-blown sand and other particles strike rock surfaces, they grind and scrape away material, gradually wearing the rock down. This mechanical action is common in deserts and along coastlines, where rocks develop smooth faces or ventifacts. Hydration, oxidation, and frost wedging involve chemical changes or freeze-thaw processes and are not driven by the abrasive action of wind, so abrasion is the correct mechanism here.
