Which risk increases when valley glaciers retreat from coastal cirques?

💡 Explanation

Increased isostatic rebound arises because the removal of glacial ice reduces the lithospheric load; this promotes rapid uplift via isostatic adjustment, rather than accelerated sedimentation. Continuous glacial erosion enables isostatic rebound.
