Which landscape evolution occurs as wind-driven aeolian removal concentrates minerals?

💡 Explanation

Desert pavement forms through deflation; finer particles are removed via aerodynamic lift leaving heavier rocks. This _selective entrainment_ creates an armored surface because only light materials mobilize. Therefore, pavement develops, rather than lakes, fans, or dunes which need sediment supply.
