We’ve all heard it—no two snowflakes are alike. However, they all seem to share that same six-sided shape, so what’s going on? Why do they follow the same rulebook for structure but still end up ...

Atmospheric conditions affect how snow crystals form and what happens to them as they fall to the ground. Snow may fall as symmetrical, six-sided snowflakes, or it may fall as larger clumps of flakes.

Snowflakes start as ice crystals (in clouds in sub-freezing air) with a basic six-sided shape because of the structure of the water molecule. The range in the shape of the microscopic lattice arms ...
