How Snowflakes Form

As the saying goes, each snowflake is different. And chances are that saying is right! Anthony and Laci join up to tell you how snowflakes form, and why each one is so unique.

"One of the true wonders of the world are snowflakes, tiny designs made of ice that are so individually unique, so detailed, and so spectacular it's hard to comprehend that they happen naturally and aren't pulled from the depths of our own imaginations." The smallest ice crystals in the world http://www.mpg.de/6362003/water-ice-c... "Nothing is as natural for us as the behaviour of water. This includes what we might have experienced in summer - a long forgotten water bottle in the freezer compartment shatters." A Fully Size-Resolved Perspective on the Crystallization of Water Clusters http://www.sciencemag.org/content/337... "The number of water molecules needed to form the smallest ice crystals has proven challenging to pinpoint experimentally." How Do Snowflakes Form?:The Science Behind Snow http://www.noaa.gov/features/02_monit... Q: How are snowflakes formed? A: A snowflake begins to form when an extremely cold water droplet freezes onto a pollen or dust particle in the sky. This creates an ice crystal. As the ice crystal falls to the ground, water vapor freezes onto the primary crystal, building new crystals -- the six arms of the snowflake. How do snowflakes get their shape? http://earthsky.org/earth/how-do-snow... "he shape of snowflakes is influenced by the temperature and humidity of the atmosphere. Snowflakes form in the atmosphere when cold water droplets freeze onto dust particles. Depending on the temperature and humidity of the air where the snowflakes form, the resulting ice crystals will grow into a myriad of different shapes."
