Cave diving with air in a cave works by using scuba tanks filled with compressed air to supply the diver with the necessary oxygen to breathe underwater. The diver carries the tanks on their back and breathes through a regulator, which reduces the high pressure of the air in the tank to the ambient pressure of the water. This allows the diver to explore the underwater cave environment while maintaining a supply of breathable air. It is important for cave divers to carefully monitor their air supply and plan their dives to ensure they have enough air to safely return to the surface. **
