A snow crystal is any of several types of ice crystal found in snow. A snow crystal is a single crystal, in contrast to a snowflake, which is usually an aggregate of many single snow crystals.

A snow crystal is any of several types of ice crystal found in snow. A snow crystal is a single crystal, in contrast to a snowflake, which is usually an aggregate of many single snow crystals.

Snow crystals, also called snowflakes, are single crystals of ice that grow from water vapour.

They form in copious numbers in the atmosphere and are well known for their elaborate, symmetrical patterns. The physics of snow crystal formation is a specific example of the more general problem of how crystals grow and develop, creating complex structures on many length scales in the process.

Because crystallization is a basic phase transition and crystals make up the foundation of several major industries, much effort has been expended toward developing a detailed understanding of the physics of crystal nucleation and growth.

There are two features of snow crystal growth—

  1. the formation of simple, faceted prism crystals as a function of temperature and supersaturation.
  2. the transition to, and growth of, dendritic structures.
