ES1405  Observe an animation of cave formation.

Over thousands of years, areas with limestone rocks can develop caves. Groundwater dissolves a network of tunnels in the rock. If the water table is lowered by a change in climate or tectonic uplift of the area, groundwater drains out of the tunnels, leaving the caverns exposed to air.
