← GeographyWhich outcome occurs when prolonged drought weakens aquifers?
A)Increased subsidence vulnerability above karst✓
B)Elevation in regional water tables
C)Decreased risk of hydrothermal explosions
D)Greater lacustrine plain bioproductivity
💡 Explanation
Drought lowers water tables; reduced pore pressure decreases support for overlying sediments which leads to subsidence involving suffosion because soluble rock layers destabilize. Subsidence risk increases rather than decreases; water tables decline; hydro explosions are unrelated.
