← GeographyWhich outcome occurs when ice exceeds cirque capacity?
A)Increased glacial abrasion and bergschrund formation✓
B)Decreased sediment supply to proglacial lakes
C)Accelerated isostatic rebound of the crust
D)Formation of thermokarst within permafrost
💡 Explanation
Increased glacial abrasion and steepening form because regelation enables ice flow over the threshold and plucking enhances bergschrund formation. The over-steepening results in an abraded steeper walls rather than sediment changes therefore affecting fewer lakes.
