Any "re-forming" is away from the cave, so the overall effect is the loss of material from the rock bulk.
Caves do not form naturally in slate with the possible exception of sea-caves (and then would be inherently unstable) and shallow rock-shelters. Slate mines (entirely artificial) can be very extensive but these are man-made.
Yarrangobilly Caves were formed by the dissolving of limestone by acidic groundwater over millions of years. The caves contain various formations such as stalactites, stalagmites, and columns created by the deposition of minerals from dripping water. The underground chambers were ultimately carved out by the slow erosion process of water flowing through the limestone bedrock.
Two features formed by underground deposition are stalactites, which hang from the ceiling of caves, and stalagmites, which grow up from the floor of caves. These formations are created as mineral-rich water drips from the ceiling and leaves behind deposits of minerals like calcite or gypsum.
There are models that show the development of caves under specific conditions in limestone rocks. Of course there are figures that show the formation and the development of a variety of passageways in caves. You can find all these staff in literature related with karst geomorphology.
Yes, sandstone can dissolve over time when exposed to acidic groundwater or rainfall. The minerals in the sandstone can react with the acidic water, leading to dissolution and erosion of the rock. This process usually occurs slowly and can result in the formation of unique landforms like caves and sinkholes.

Caves are typically formed by a combination of erosion and weathering. Erosion from water, wind, and ice can wear away rock formations, while weathering processes such as chemical weathering can dissolve minerals in the rock, creating openings that can eventually form caves over time.
well to be nice i am not smart
Stalactites in caves are typically formed from minerals such as calcite or aragonite, which are deposited by dripping water containing dissolved minerals. These minerals precipitate out of the water over time, creating the elongated formations we see in caves.

Groundwater can dissolve minerals in the rock over time, creating underground cavities as the water flows through the rock. The dissolved minerals are carried away by the water, leaving void spaces that eventually form into caves. Over long periods of time, erosion and deposition can also help shape these formations into the caves we see today.
Caves are mainly the result of natural geological processes, such as the dissolution of rock by water or chemical weathering. In most cases, caves are formed in limestone or other soluble rocks where water can dissolve the rock over time, creating underground voids. Additionally, caves can also be formed by volcanic activity, glacier movements, or erosion by wind.
Caves that have cacium carbonate in their geology. The calcium carbonate dissolve in water, but as that water evaporates the calcium carbonate is left behind. It gradually forms a spike from the ceiling or the floor as the drips evaporate leaving behind their solutes.
Stalagmites grow from the ground in caves. They are formed by the accumulation of minerals deposited by water dripping from the ceiling of the cave.
No. Most caves are formed out of limestone making that false.
Bacteria do not form caves directly. However, they can play a role in cave formation through processes like bioerosion, where they break down rocks and minerals. Over time, this can contribute to the creation or enlargement of caves.
Fissure, Talus, Solutional, Granite, Slate, Erosional, man-made, rare emerged Sea caves, Sea caves, and Sandstone caves.Most are created over millions of years by water dissolving minerals in the rock, leaving a void or hollow behind.
