← GeographyDuring prolonged droughts, which outcome disproportionately affects silty topsoil?
A)Increased incidence of dust storms✓
B)Accelerated chemical soil weathering
C)Enhanced development of duricrust layers
D)Diminished rates of soil creep
💡 Explanation
Increased dust storms correlate highly with desert silty topsoil undergoing droughts because wind erosion via selective particle entrainment called deflation preferentially removes small, loosely bound particles making larger dust storms, rather than slower chemical alteration during wetting/drying or soil modification.
