Which outcome results when high winds affect parabolic dunes?

A)Blowout formation on the windward side
B)Stabilization due to vegetation growth
C)Increased slipface development leeward
D)Migration towards the prevailing wind

💡 Explanation

Blowout formation occurs with wind erosion on the dune crest because the wind scoops sand, undercutting vegetation via deflation processes; therefore the windward side erodes, rather than becoming stable or migrating forward into the wind.
