← GeographyWhich pattern emerges when limited vegetation cover disrupts aeolian transport?
A)Parabolic dune formation upwind of vegetation✓
B)Barchan dune alignment towards wind source
C)Longitudinal dune stabilization parallel to wind
D)Transverse dune amalgamation creating increased erosion
💡 Explanation
Parabolic dunes form because vegetation anchors dune arms, hindering sand movement relative to the center during aeolian transport, therefore leading to a U-shaped dune concave upwind, rather than dunes dictated by wind direction.
