SNOWFLAKE

A snowflake or a snow crystal. This snow crystal is of a stellar crystal form, also called a dendritic snow crystal. This form of crystal is made in a cloud when water freezes into ice around -15C. This image has been edited to remove the dark background and show the shape of the crystal. Snowflakes show typical hexagonal symmetry (as seen here) if the crystallization occurs slowly, in a 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 stage is influenced by the weather conditions in which they form, no two snowflakes are identical.
