## Caption

How are agates formed? The answer is less crystal-clear than you might expect. They form in swiss cheese-like cavities in other rocks; as water percolates through the holes, the mineral silica begins to crystalize. Differences in crystal structure form the agate's distinct layers - but the reason for these differences isn't fully understood. 🔍👀
