As time passed the limestone, which is permeable and soluble, was eroded by water. Weak carbonic acid in rainwater, reacting with the chemicals in the rock, dissolved and eroded away the limestone as the water filtered into the underlying depths of sediments. Large hollow solution cavities were formed in the limestone in this way.

Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.

How are geodes formed? Geodes essentially start out as hollow bubbles in rock; created by animal burrows, tree roots, or volcanic eruptions. Over time, pockets of air in the hollow rock receive deposits of minerals as groundwater seeps into the rock. Even after the water evaporates, the minerals remain and eventually become crystals.
