Which effect results when seasonal cave flooding mobilizes sediments?

💡 Explanation

Enhanced cave passage widening happens because the water's abrasive action (abrasion) mechanically erodes passage walls, thereby accelerating dissolution rates. This leads to broader tunnels rather than other alterations, because abrasion requires sediment and flow volume rather than temperature or gases.
