← GeographyWhich outcome develops on exposed bedrock when deflation is concentrated by topographic constrictions?
A)Formation of sculpted ventifacts✓
B)Development of loess sediment layers
C)Creation of ephemeral playa lakes
D)Extensive alluvial fan deposition
💡 Explanation
Sculpted ventifacts form because concentrated deflation by wind abrasion etches and smooths rock surfaces. This creates distinct shapes aligned with dominant wind directions, rather than depositing sediments; therefore 'ventifacts', rather than other depositional features arise.
