← GeographyWhich outcome occurs in a karst cave system when the water table drops?
A)Increased speleothem formation accelerates
B)Accelerated collapse due to buoyancy loss✓
C)Surface water contamination risk decreases
D)Allochthonous sediment deposition halts
💡 Explanation
Lower water levels reduce buoyant support, increasing the risk of cave ceiling collapse via Gravitational stress failure. Because cave structures were partially supported by water pressure, therefore structural integrity declines rapidly now, rather than improve from drying effects (A).
