Which consequence results when prolonged drought lowers subterranean water tables within karst regions overlying fractured limestone?

💡 Explanation

Increased sinkhole collapses occur because lowered water tables remove buoyant support; void spaces enlarge due to mechanical COMPACTION. This leads to surface subsidence and new sinkhole formation rather than preventing ground deformation because of internal support.
