← GeographyWhich outcome typically results when rapid snowmelt saturates a pre-existing karst system above a municipal area?
A)Widespread coverage due to sheetwash
B)Localized accelerated sinkhole formation✓
C)Uniform infiltration lessens erosion
D)Increased surface flow in entrenched streams
💡 Explanation
Rapid saturation elevates the water table, increasing pore pressure and dissolving limestone via solution weathering; sinkhole formation accelerates because of reduced support, therefore localized collapse is more likely, rather than even areal saturation.
