While the water table was high, the water in the cavern helped to support the roof of the cavern. This support is removed when the water table is lowered, and thus the unsupported roof eventually becomes unstable and collapses to form a sinkhole.Sinkholes may also form by slow enlargement of caverns by continued dissolution of the limestone ...

Most of cave formation occurs in limestone, below the water table. Most cavern formation ends here. The water table drops below the cave level and the cave becomes an open space filled with air. Sometimes, the ground water has calcite that goes downward, emerges from the rock above the cave and from the ceiling and the cave surface changes.
