← GeographyWhich sinkhole formation risk increases when groundwater cave ceilings collapse?
A)Reduced aquifer recharge capacity
B)Accelerated surface soil erosion✓
C)Increased localized seismic activity
D)Diminished downstream sediment deposition
💡 Explanation
Increased surface soil erosion increases because the mechanical weathering mechanism removes the cave’s support, inducing collapse events and unstable ground, therefore triggering erosion, rather than seismic changes since tectonic forces don't directly cause cave collapses.
