Final answer:
The type of snowflakes shown in the picture are called hexagonal snowflakes. They have a symmetrical hexagonal shape and are formed from ice crystals in a hexagonal lattice structure.
Step-by-step explanation:
The type of snowflakes shown in the picture are called hexagonal snowflakes. These snowflakes have six sides and a symmetrical hexagonal shape.
Each branch of the snowflake is made up of ice crystals that form in a hexagonal lattice structure. This structure is due to the way water molecules arrange themselves in a regular pattern when they freeze.
The hexagonal shape and intricate patterns of snowflakes are formed as the water vapor in the air freezes onto the ice crystals, creating unique and beautiful designs.
