A geode forms through a series of four key steps: First, mineral-rich water seeps into cavities in volcanic or sedimentary rock. Second, as the water evaporates, minerals precipitate and deposit onto the cavity walls. Third, these minerals crystallize over time, creating the inner structure of the geode. Finally, the outer shell solidifies, encasing the crystal formation, which can be revealed when the geode is cut open.

What causes a geode to be hollow or solid?

A geode starts out as basically a cavity or pocket in otherwise solid rock. The cavity walls grow inward as mineral crystals grow from solutions that seep into it. In time, the cavity may become completely infilled with mineral crystal. The geodes that are found on the surface are survivors of weathering which eroded the rock in which they were once emplaced. This is because the geodes are composed of minerals such as quartz which are more resistant to erosion than the rocks which originally surrounded them.

Can geodes have water in them?

Yes, geodes can sometimes have water trapped inside them. This water is typically formed when minerals are dissolved in the groundwater that fills the cavity of the geode, and then crystallize as the geode forms.
