The x, y dimensions of snowflakes get all the attention for obvious reasons, but the z dimension must be interesting too, in its own humble way. In fact, I have lived more than half a century and never seen anyone refer to snowflakes' third dimension at all!
So I'd like to know what a snowflake's cross-section looks like, and what forces/phenomena make it that way.
There are numerous possibilities:
- that snowflakes are a single molecule thick
- single crystal thick then grown over with hoarfrost
- thousands or millions of nearly identical snowflakes glued together like slices in a loaf of bread
- something else
No doubt, the ratio between x and y dimensions is extremely similar across all snowflakes, but an interesting part of the phenomena involved would be that which defines the ratio between x and z dimensions.
