Which risk increases when heavy rainfall saturates limestone bedrock?

💡 Explanation

Increased saturation elevates pore water pressure, causing sediment instability; the mechanism is effective stress reduction. Solutional weathering dissolves the limestone, therefore sinkhole formation accelerates rather than tectonic or glacial outcomes because it alters subsurface support.
