Snowflakes

A snowflake is essentially a piece of ice falling to the ground. A snowflake is a crystalline form of ice. Snowflakes come in many different forms and shapes. It is said that no two snowflakes are ever alike. So while each snowflake is unique, snowflakes do have characteristics in common. They are all hexagonal. This means that they all have six sides or branches. Snowflakes are also symmetrical.

There are many different types of snowflakes. One of the forms is called the stellar dendrites. This form looks like six trees extending from the center. Another form is the sector plate. These snowflakes have plate-like arms that extend from the center. These are made from flat, slender pieces of ice. Spatial dendrites are another form of snowflake. These snowflakes are not flat and slender pieces of ice. These snowflakes are made from individual snowflakes all jumbled up together. Branches of these crystals extend from the center.
