Which outcome occurs when groundwater becomes highly acidic in karst regions due to agricultural fertilizer runoff?

💡 Explanation

Accelerated sinkhole formation occurs because agricultural runoff acidifies groundwater, increasing carbonic acid concentrations and dissolving limestone via the process of chemical weathering, thus expanding fractures more rapidly; therefore, subsidence accelerates with acidic water rather than slower rates without those compounds.
