← GeographyWhich risk increases when tectonic uplift obstructs glacial meltwater flow?
A)An increase in glacial lake outburst floods✓
B)A decrease in regional seismic activity
C)A decrease in geothermal vent formation
D)An increase in regional biodiversity
💡 Explanation
Glacial Lake Outburst Floods increase because impoundment of meltwater increases hydrostatic pressure until the barrier fails via hydrofracturing, therefore creating a sudden release of water, rather than gradual drainage or harmless subsurface flow.
