Hexagonal snowflake. Snowflakes are ice crystals that form in air that has a temperature near the freezing point of water. If the air is calm,then a symmetrical,hexagonal snowflake can form. When the growth is slow,the hexagonal,plate shape can be preserved. Usually,branching instabilities and changing temperatures cause complex and beautiful patterns to form as a snowflake increases in size. The hexagonal symmetry of a snowflake is due to the orientation of the water molecules within the lattice of an ice crystal | |
