← GeographyWhich consequence results when differential lithification rates affect mesa erosion?
A)Formation of prominent caprock ledges✓
B)Decreased overall watershed sediment yield
C)Stabilization of the regolith profile
D)Reduced frequency of debris flows
💡 Explanation
The formation of caprock ledges follows from differential lithification because higher-resistance rock slows erosion rates where it overlays weaker materials; therefore, sharp topographic features like ledges form, rather than uniform slope retreat where lithification is even.
