Which mechanism roughens desert pavement where ventifacts originate?

💡 Explanation

Aeolian abrasion polishes upwind rock faces because wind-transported sand erodes the surfaces; therefore smooth, faceted ventifacts form on desert pavement, rather than continuous dust cover due to finer particles only.
