Which outcome occurs when strong, persistent winds encounter parabolic dune fields?

💡 Explanation

Deflation basins form because the wind removes sand from between dune arms, eroding the surface via deflation; therefore basins deepen rather than stabilizing. Slipface movement or altered dune shapes are less likely without changes in prevailing wind direction.
