Answer:
Caverns are created when moving groundwater mechanically weathers sediment and transports it elsewhere, leaving behind large empty spaces.

Mechanical weathering plays an major role in creating caverns by dissolving of limestone rock due to acidic water that reacts with limestone and removes it with the passage of time that forms caves. The normal pH water can't perform this job due to no reaction occurs with limestone.
