Which feedback results when sustained aeolian abrasion forms ventifacts?

💡 Explanation

Increased surface roughness results from ventifact creation because differential erosion enhances aerodynamic drag creating turbulent airflow, therefore subsequent abrasion is accelerated rather than being dampened by smooth surfaces.
