← GeographyAfter prolonged drought, which topographical consequence develops because of aeolian deflation?
A)Lag deposits (desert pavement) form✓
B)Barchan dunes become parabolic dunes
C)Yardangs elongate along wind direction
D)Sand seas stabilize through vegetative cover
💡 Explanation
Lag deposits form because wind deflation winnows away fine particles, leaving behind larger rocks and gravel; this forms desert pavement. The result is surface armouring, therefore protecting the underlying sediment rather than processes affecting shifting dunes, stabilization or yardang formation.
