Which subsurface outcome enhances sinkhole formation during rain?

💡 Explanation

Sinkholes enlarge due to carbonate dissolution: rainwater carrying carbonic acid promotes increased chemical weathering (leaching) via dissolution. Because the removal of underlying rock leads to collapse, increased mineral dissolution causes sinkhole enlargement, rather than increased stability facilitated by vegetative consolidation.
