← GeographyWhich outcome occurs when 'regelation' inhibits ice flow within a cirque?
A)Crevasse formation reduces overall erosion
B)Abrasion increases at the cirque floor✓
C)Bergschrund development slows headwall erosion
D)Plucking decreases at the glacier base
💡 Explanation
Abrasion increases at the cirque floor because restricted ice flow concentrates the glacial weight and scouring action due to basal sliding; therefore, enhanced grinding sculpts the bedrock, rather than crevasse or bergschrund development affecting overall cirque erosion rates.
