This dust can come from volcanoes, flower pollen, meteorites falling stars, soil erosion and much more. Snow begins forming in a very cold cloud that has both super cold water droplets and ice crystals. When water vapor droplets collide with a piece of already formed ice crystal, the droplet freezes to it making it grow into a slightly larger new ice crystal. The shape of the snow crystal is determined by the temperature in the cloud. The size of an ice crystal is determined by moisture in the cloud. It is one of the mass of small thin delicate arrangements of ice crystals that fall as snow. In Korea, we call snowflake as snow flower. I have been live in California for almost nine years. It is really hard to see snow in here. In my memory, I think, actually I did not see Snowflake before, but I knew how it looks like very well because people use the design for accessories a lot.
