Does a Snow Crystal Have?

A snow crystal is a single crystal of ice, but a snowflake can be an individual crystal, or as many as 200 stuck together to form the big "puff-balls" that often fall when the temperature is just below freezing. ... The water molecules in ice form a hexagonal (six-sided) lattice, and all snow crystals have six sides.

Do snow crystals have arms?

This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals – the six arms of the snowflake. ... The intricate shape of a single arm of the snowflake is determined by the atmospheric conditions experienced by entire ice crystal as it falls.

What are the characteristics of a snow crystal?
