← GeographyWhich outcome results when rapid groundwater withdrawal from a karst aquifer accelerates?
A)Increased incidence of sinkhole formation✓
B)Decreased surface stream discharge
C)Enhanced travertine terrace formation
D)Reduced cave system air ventilation
💡 Explanation
Increased groundwater removal lowers hydrostatic support, driving soil into voids through suffosion. The resulting ground collapse causes sinkhole formation rather than reduced surface flow, because diminished support is the direct mechanism, therefore it overcomes drainage network stability.
