Caves are formed mainly by dissolussion due to hydrothermal circulation. time varies depending on minerals forming limestones, and the nature of the desolving solution, but it must be in order of 100 of thousands to million years
Caves form in limestone (calcium carbonate), and occasionally in dolomite (calcium magnesium carbonate), when water containing dissolved carbon dioxide (carbonic acid) seeps into rock crevices and joints.
As time passed the limestone, which is permeable and soluble, was eroded by water. Weak carbonic acid in rainwater, reacting with the chemicals in the rock, dissolved and eroded away the limestone as the water filtered into the underlying depths of sediments. Large hollow solution cavities were formed in the limestone in this way
Limestone Cave is a type of solutional Cave, limestone dissolved by natural acid in groundwater. that seeps through joints, bedding planes, faults, craks, which is leading to caves. chemical weathering of rocks. depend on acidic groundwater flow and duration.
The important thing in the Limestone caves formed is DIAGENTIC Process was valid in Limestone with the long period thousand or million years ago.

depend on acidic groundwater flow and duration.
Limestone caves are formed in the dry areas, when the water flowed on the lime stone terrain it chemically reacted and leached then formed as a as a cave few to several Kilometers. the period of formation of these caves are based on the water flow, climatic condition of the environment.
A cave is a natural opening or cavity within the earth, generally extending from the earth's surface to beyond the zone of light. Three generic classes of caves can be recognized according to the major sculpturing process:
(1) caves formed by pressure or flow
(2) caves carved by erosion
(3) caves dissolved by solution. Those structures formed by mechanical pressure or flow include lava tunnels
