Which consequence results when enhanced rainwater acidity affects karst regions?

💡 Explanation

Increased acidity enhances the dissolution of calcium carbonate in limestone regions; this chemical weathering, known as carbonation, accelerates formation of subsurface voids because acid breaks down the rock, rather than altering soil composition, therefore increasing subsurface collapses.
