Snow is a type of precipitation in the form of crystalline water ice, consisting of a multitude of Snowflakes that fall from clouds. The process of precipitation is called Snowfall. Large, well formed Snowflakes are relatively flat and have six approximately identical arms, so that the Snowflake
nearly has the same 6-fold dihedral symmetry as a regular hexagon or
hexagram. This symmetry arises from the hexagonal crystal structure of
ordinary ice. However, the exact shape of the Snowflake is determined by the temperature and humidity at which it forms.. Rarely, at a temperature of around −2 °C (28 °F), Snowflakes can form in threefold symmetry — triangular Snowflakes. Snowflakes are not perfectly symmetrical however. The most common Snowflakes are visibly irregular, although near-perfect Snowflakes may be more common in pictures because they are more visually appealing.
