ice crystals
Snowflake building blocks
Ice crystals are small formations of frozen water with geometric structures, typically hexagonal.
They form when water vapor freezes directly or when liquid water crystallizes slowly.
Ice crystals make up snow, frost, and the delicate patterns on cold windows.
In meteorology, ice crystals refer to precipitation of tiny ice particles falling from high clouds: The pilot reported ice crystals at altitude.
