Snowflake melt sequence (left to right), light micrographs. 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. The two main growth patterns observed are faceting and branching, producing plate or dendritic snowflakes, or a combination of both. | |
