Which process primarily weakens limestone karst formations during heavy rainfall?

💡 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.
