Answer:
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. 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.
