← GeographyWhich outcome increases when meltwater volume rises within a cirque?
A)Glacial abrasion rate accelerates markedly✓
B)Crevasse formation depth stabilizes shallowly
C)Esker sedimentation grain size lessens
D)Kettle lake drainage pathway expands
💡 Explanation
Glacial abrasion accelerates greatly because regelation refreezes water at the ice-bedrock interface, causing increased erosion. This outcome happens due to pressure melting, rather than crevasse patterns, esker formation, or kettle lake behavior within a cirque environment.
