sinkhole
A large hole in the ground formed when the roof of a cavern collapses is known as a sinkhole. Sinkholes can vary in size and are typically caused by natural processes such as erosion and the dissolution of soluble rocks like limestone.
Sinkholes form typically as limestone dissolves. A caldera is created by the collapse of volcanic vault ceilings.
Cavern formation can be related to mass wasting when the roof of a cavern collapses due to material being eroded or removed from the surrounding area by mass wasting processes. This can weaken the structural integrity of the cavern, leading to a collapse event. Additionally, mass wasting can also occur within a cavern if loose material on the walls or floor is destabilized by the movement of the cavern walls during mass wasting events.
Two features formed by underground weathering are caves and sinkholes. Caves are formed by the dissolution of limestone or other soluble rocks, creating underground chambers and passages. Sinkholes are depressions in the ground that form when the roof of an underground cavern collapses.

Shakehole or Sinkhole - when the collapse extends to the surface. (Not all cave roof collapses disturb the surface above.)
A sinkhole is formed when the roof of a cave collapses.
Caves are underground. They are big long holes underground. Sometimes, for some unknown reason, the roof of the cave can no longer support the weight of the ground above it and the ground collapses down into the cave. The land sinks. It fills the hole. Where there was a cave, there is now solid ground. Where there was land, there is now a big hole. So, you have a sinkhole when the roof of a cave collapses.

Weathering weakens the bedrock beneath the surface, making it susceptible to erosion. Water seeps into the cracks in the bedrock, dissolving it and creating underground caverns. Eventually, the roof of the cavern collapses due to gravity, creating a sinkhole.
