← GeographyWhich geologic event occurs when prolonged deflation lowers elevation?
A)Development of desert pavement✓
B)Formation of parabolic dunes
C)Creation of alluvial fans
D)Glacial valley widening
💡 Explanation
Deflation removes fine particles; desert pavement forms because wind carries away silt and sand, leaving larger rocks behind. Therefore, pavement develops rather than dune formation, which requires deposition, or alluvial fans, which form from fluvial deposition.
