← GeographyWhich outcome occurs when localized wind shear increases overland?
A)Development of deflation hollows begins✓
B)Dunes stabilize with vegetation cover
C)Flash floods erode desert pavements
D)Chemical weathering accelerates rock fracturing
💡 Explanation
Deflation involves removal of loose material under wind action; localized wind scour exceeding a threshold triggers particle lifting away from a surface because aerodynamic lift reduces resisting gravity, therefore deflation hollow formation occurs, rather than stabilization or other erosional patterns.
