← GeographyWhich landscape evolution occurs as wind-driven aeolian removal concentrates minerals?
A)Formation of desert pavement lag✓
B)Increased playa lake sedimentation
C)Accelerated alluvial fan development
D)Heightened sand accumulation into erg
💡 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.
