Stellar dendrite snowflake, light micrograph. 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. When growth is fast and unstable, branching patterns create a dendritic snowflake (seen here in a star shape or stellar form). Slower growth allows the straight lines and hexagonal shapes of a plate snowflake. | |
