Snow crystals are single crystals of ice while a snowflake is one or more crystals stuck together. Water molecules create a hexagonal lattice that is formed when water vapor condenses directly into ice in clouds when the temperature is freezing or below. There are several factors that influence the shape of snowflakes: humidity, temperature, and air currents. Colder temperatures create more intricate shapes – sharper tips and more branching.
