NATUR SCHNEEFLOCKE
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. (KEYSTONE/SCIENCE PHOTO LIBRARY/Kenneth Libbrecht) === ===
