Which hydrological disruption results when rapid melting destabilizes cirques?

💡 Explanation

Glacial lake outburst floods increase as ice dams collpase; this is because ablation causes increased meltwater accumulation behind unstable moraines, therefore generating sudden discharges of a huge water volume into surrounding areas, rather than gradual runoff.
