Which outcome occurs when glacial meltwater floods supraglacial lakes atop ice sheets?

💡 Explanation

Accelerated glacial calving of velocity events results because hydrofracturing weakens the ice, as water drains through crevasses via positive feedback. This undercutting rapidly destabilizes glacial fronts; therefore, calving speed increases, rather than enhanced albedo caused by widespread flooding.
