← GeographyWhat outcome arises where concentrated groundwater extraction accelerates cover subsidence sinkhole collapses?
A)Increased frequency of infrastructure damage✓
B)Enhanced purification of aquifer recharge
C)Decreased sedimentation in downstream drainage
D)Stabilization of subsurface geological structures
💡 Explanation
Increased infrastructure damage will occur because drawdown lowers water pressure, which elevates the effective stress, initiating particle rearrangement from suffosion leading to sinkholes; therefore, collapses damage infrastructure instead of purification, sedimentation, or stabilization, due to different mechanisms.
