Which outcome occurs when prolonged wind erosion in hyperarid regions reaches a resistant substrate?

A)Formation of extensive loess deposits
B)Development of desert pavement (reg)
C)Creation of large barchan dune fields
D)Intensified chemical weathering rates

💡 Explanation

Desert pavement forms because deflation removes finer particles, leaving behind larger rocks. This lag deposit armors the surface, therefore it slows further erosion, rather than forming loess which requires transport or dunes that require sand accumulation.
