← GeographyWhich outcome on leeward dune slopes results from turbulent air?
A)Formation of slipface avalanches✓
B)Reduced sand transport capacity
C)Increased sediment grain sorting
D)Stabilization by vegetation growth
💡 Explanation
The formation of slipface avalanches appears on leeward dune slopes because turbulent airflow causes grainfall and increased shear stress at the crest from wind loading, triggering avalanches; therefore slipface formation accelerates wave migration, rather than the other options occurring inland without additional weather factors.
