Most caves are in limestone, and their passagesare active or former stream-courses, the cavities themsleves having formed primarily by weakly-acidic rain water dissolving the limestone.
It takes tens or hundreds of thousands of years to do so. I think a rate of lowering or rock surface for a cave stream in Carboniferous Limestone in temperate climates can be around 2 or 3mm/100yrs.
There are other cave types such asLava Tubes, from molten rockrunning out from under a solidified crust, and Mass-Movement Fissures, which are a land-slip feature.
Passages in caves are typically formed through a process called dissolution, where underground water dissolves and erodes the rock over time, creating tunnels and caverns. This can happen when acidic water interacts with certain types of rock, such as limestone, to gradually create cave passages.ervoir.
A place where many caves are connected by passages is called a cave system. These systems form when multiple caves are interconnected underground due to geological processes such as erosion or the dissolution of rock by water. They can create complex and intricate networks of tunnels and chambers beneath the surface.
Connected caves are called cave systems. These systems occur when several cave passages interconnect and form a complex network of underground tunnels and chambers.
Compound relict caves are a type of cave system that has multiple levels and passages, typically formed through a combination of erosion and tectonic processes. These caves often have intricate networks of chambers and tunnels, creating complex underground environments.
Caves with passageways are typically referred to as cave systems or cave networks, as they consist of interconnected passages, chambers, and tunnels. These cave systems can vary in complexity and size, with some spanning vast underground areas.
A system of caves is typically referred to as a cave system or cave complex. It is a network of interconnected underground tunnels, chambers, and passages formed by natural geological processes such as erosion, dissolution, or lava flows.

Some cave passages are very humid because they do not have good ventilation. These wet caves cannot release their moisture making them very humid.

Mammoth Caves - to give the right spelling - is a complex and extraordinarily extensive system of several connected caves, making it the world's longest known system; but it was developed by the normal karst processes that form caves in limestone. I.e. dissolution of the rock by weakly-acidic ground-water. As for "was", if any of its passages are carrying streams now, those "active" passages are still forming.
Do you mean "water in caves"? That depends on the individual cave, but passages can vary from being permanently full of water to being abandoned and left high-and-dry bylosing their formative streams.

Smugglers used caves because they provided hidden and secure locations to store and conceal contraband goods, making it difficult for authorities to discover and confiscate them. Caves also offered protection from the elements and the ability to easily transport goods through secret passages or tunnels.
Caves, caverns, and sinkholes are typically formed by the dissolution of soluble rocks such as limestone, dolomite, or gypsum by water. Over time, water erodes and dissolves the rock, creating underground cavities and passages. Eventually, these cavities can collapse or become exposed at the surface, forming caves, caverns, and sinkholes.
