← GeographyWhich process primarily weakens limestone karst formations during heavy rainfall?
A)Acidification via differential dissolution✓
B)Deposition of infiltrated silica
C)Weathering via salt crystallization
D)Erosion impact from hydraulic action
💡 Explanation
Acidification due to differential dissolution leads to weakening of limestone because rainwater absorbs atmospheric CO2, creating carbonic acid; this enhances leaching of calcium carbonate, thus weakening the overall karst structure rather than merely mechanically eroding it.
