How do caves and caverns form? What will be an ideal response?
Groundwater percolating through the zone of aeration dissolves the carbonate rock and enlarges its
fractures and bedding planes. On reaching the water table, the groundwater migrates to the surface.
The groundwater continues to dissolve rock in the zone of saturation and forms a system of horizontal
passageways. The surface streams erode deeper, the water table drops, and a new set of passageways
begin to form. The water abandons the channel ways and leaves a set of caves and caverns
