Which outcome results when glacial meltwater exceeds evaporation?

💡 Explanation

Proglacial lakes form outside of glaciers due to increased meltwater. Positive feedback accelerates this process because increased volume undergoes ablation more rapidly due to **thermal erosion**, therefore lake formation accelerates, rather than it declines because of less effective ice damming.

• When breached, which outcome occurs in volcanic tephra dam?
• Which feedback results when previously vegetated sand dunes lose their plant cover?
• Which mechanism forms lagoon ecosystems behind coastal barriers?
• Which outcome results when deep-sea organisms enhance bioturbation?
• Which outcome follows water inclusion in subducting slabs?
