← GeographyWhich outcome occurs when rapid snowmelt increases stream discharge into glacial lakes?
A)Increased glacial lake outburst floods✓
B)Decreased downstream sediment deposition
C)Enhanced coastal erosion stability
D)Reduced seasonal thermocline formation
💡 Explanation
Increased discharge elevates hydrostatic pressure; this overloads moraine dam structural integrity, activating the mechanism of hydraulic fracturing. Therefore, glacial lake outburst floods become more likely because the dam is weakened, rather than decreasing downstream deposition or enhancing coastal stability under the increased flow.
