Caverns are created when moving groundwater mechanically weathers sediment and transports it elsewhere, leaving behind large empty spaces.
Explanation:
The movement of groundwater causes erosion that is responsible for the formation of caves. These caves are formed due to mechanical weathering of rocks.
