Winter Hush

It is quieter after a fresh snowfall because the fluffy new snow, like acoustic tile, is full of tiny air spaces that absorb sound. Snow forms when water droplets become super-cooled (temperature below freezing) and find a surface, like a dust particle, to crystallize around. At different temperatures the rate of crystal formation varies, thus producing the multitude of crystal forms that fall as snow. Fast growing crystals often exhibit complex forms; slow growing crystals often assume hexagonal needle shapes. Watch the next time it snows and see if you can pick out different crystal shapes.
