Which hazard increases where soluble bedrock collapses suddenly?

💡 Explanation

Increased flash flooding occurs because sinkhole formation via **dissolution** creates pathways for concentrated surface runoff; therefore, flood peaks rise and spread rapidly, rather than infiltrating gradually through resistant soil.
