← GeographyWhich outcome arises when high winds exceed threshold friction velocities across desert dunes?
A)Increased suspended sediment transport✓
B)Stabilized dune crest morphology
C)Diminished abrasion of adjacent surfaces
D)Decreased formation of barchan dunes
💡 Explanation
Increased suspended sediment load occurs because saltation destabilizes the surface through aerodynamic lift, leading to increased grain detachment; this leads to greater transport through suspension, rather than stabilized dunes because the wind force exceeds the surface stability.
