A snowflake typically has a hexagonal shape. This characteristic structure arises from the molecular arrangement of water molecules (H2O) when they freeze. As water vapor crystallizes, it forms intricate patterns and symmetrical shapes, influenced by temperature and humidity during the formation process. Each snowflake can have unique features, resulting in the common saying that no two snowflakes are alike. The six-fold symmetry of snowflakes is a result of the hexagonal lattice structure of ice. This fascinating phenomenon is a reminder of the beauty and complexity of nature, particularly in winter weather.
