← GeographyWhich topographic change follows limestone dissolution near fracking wells?
A)Increased sinkhole formation around the fracture✓
B)Glacial moraine deposition enhancements nearby
C)Accelerated alluvial fan sedimentation increase
D)Decreased volcanic caldera land subsidence
💡 Explanation
Increased sinkhole formation is caused by chemical weathering because fractures introduce acidic water into the limestone matrix, which increases the rate of dissolution; therefore, sinkhole prevalence rises near fractures rather than deposition or changes in volcanic processes.
