← GeographyWhich outcome is amplified by the increased frequency of dust storms in playas?
A)Formation of desert pavement (reg)✓
B)Increased rate of alluvial fan deposition
C)Higher levels of chemical weathering
D)Intensification of soil horizon development
💡 Explanation
Reg formation increases because increased dust storm frequency leads to higher “deflation”, the removal of fine particles, which leaves larger rocks on the surface, contributing to desert pavement creation rather than deposition or weathering.
