What Makes The Different Shapes? The shape that a snow crystal will take depends on the temperature at which it was formed.
- When the temperature is around 32°F to 25°F thin six-sides plates are formed.
- At 25°F to 21°F long needle shapes are formed.
- At 21°F to 14°F hollow columns are formed.
- At 14°F to 10°F six-point stars are formed.
- At 10°F to 3°F dendrites are formed.
- The colder it is outside, the smaller the snowflakes that fall.
- The fluffiest snow falls at temperatures around 15°F.
