The joints, bedding-planes and faults provide conduits for water to penetrate the limestone mass; and it is the water, slightly acidified by absorbed carbon dioxide, that dissolves the rock to form the cave.

limestone
erosion and uplift
Principally, as by far the majority of the world's caves are formed in limestone uplands, by dissolution of the rock's calcium carbonate by slightly acid rain-water seeping through the joints and bedding-planes. These, and other discontinuities such as faults and shale bands, provide a "leak path" for the initial penetration of water into the rock mass, though the water also has to find an outlet at a lower altitude from the inlet for flow to take place. . In time the water forms discrete conduits along the joints etc through the rock, and these coalesce to develop passages and chambers. The passages will continue to develop as long as they carry their streams. . This can happen only in soluble rocks: limestone and gypsum. Caves in other, insoluble, rocks are developed by other mechanisms.
Oceans push rocks underground to form caverns.
Carbonic Acid
Dissolution of the limestone's primary constituent (calcium carbonate) by ground-water passing through the rock's joints, bedding-planes and faults from catchment to rising. To achieve it the water is rendered slightly acid by absorbed atmospheric CO2 (carbonic acid).

Crystal form refers to the geometric shape the mineral acquires upon solidification. Cleavage is a mineral property that describes the tendency of a crystal to break along planes of weakness.
Sleaford Joint Sixth Form was created in 1983.
No, the word joint is not an adverb.The adverb form of the word "joint" is jointly.
