← GeographyNear a large quarry, which outcome results when groundwater acidity increases beyond limestone dissolution equilibrium?
A)Localized sinkhole development accelerates tenfold✓
B)Dissolution rates stabilize near previous levels
C)Regional water tables experience a sharp drop
D)Increased seismic activity near the excavation
💡 Explanation
Increased acidity enhances the chemical weathering mechanism called dissolution, causing voids underground; because increased dissolution destabilizes the overburden, pre-existing weaknesses collapse to form sinkholes; therefore sinkhole development drastically accelerates rather than stabilizing or dropping the water table.
