Which increasing risk results when intense rainfall interacts with existing karst topography?

💡 Explanation

Increased ground saturation weakens subsurface support because dissolution causes voids; therefore, sinkhole formation risk escalates. This occurs due to enhanced chemical weathering, rather than increased recharge which requires intact soil.
