Most caves are in Limestone, and develop by ground-water dissolving the rock as it percolates through the rock's joints & other discontinuities.
The water is rendered acid so it can dissolve the calcium carbonate by absorbed atmospheric CO2 (becoming Carbonic Acid).
Erosional caves are formed by the action of water or wind.
No. Most caves are formed out of limestone making that false.
The Maquoketa caves in Iowa were formed through years of natural non-glacial erosion.
Wookies live in trees, not caves.

Limestone caves are formed through a process called chemical weathering. Rainwater, which is slightly acidic, dissolves the limestone rock over time, creating small cracks. These cracks then widen as more water flows through, eventually forming caves. Additionally, some limestone caves are formed through the erosion of underground rivers.
Erosional caves are formed by the action of water or wind.
They - or it? - are normal karst caves, formed in limestone by its dissolution by water. I believe they still carry a stream: if so they are still forming.
Other way round! Water and/or air are in caves.:-) Most of the world's caves have formed / are forming in limestone.
Karst caves, and it is the majority of caves; formed by acidic ground-water dissolving the limestone.
