crystal seen on a cloudy sky. Snowflakes show a typical hexagonal symmetry (as seen here) if the crystallisation occurs slowly ,in calm air and in temperatures near freezing point. They are commonly flat and may have different shapes such as six sided polygons or stars. The beautiful pattern is often very complicated with needle-like structures and tiny bridges. Since the final shape is influenced by the weather conditions in which they form,no two snowflakes are identical | |
