A sinkhole forms.
Caverns and sinkholes are both formed in limestone bedrock by the process of dissolution, where groundwater dissolves the rock. Sinkholes are formed when the roof of a cavern collapses, resulting in a depression on the surface. So, caverns can be an intermediate stage in the formation of sinkholes.
When rock above a cave collapses, a sinkhole is formed.
