This snowflake 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. 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 | |
