Which risk increases when urban storm drains discharge into soluble bedrock?

💡 Explanation

Accelerated sinkhole formation occurs because increased water flow via drains enhances chemical weathering due to limestone dissolution. This **dissolution** weakens the rock structure, therefore sinkholes form more readily; rather than surface flooding, the water infiltrates the expanding void.
