response: The differences in temperature and humidity are reaponsible for creating all the different patterns.
history: I love winter season becuase it is so beautiful when the snow covers the parks! Snowflakes are formed by the attraction of super-cooled water to a particle. That is very informative! Another thing about snowflakes are that the pattern that they are formed in is always different from the next.
knowledge: Complex shapes emerge as the flake moves through differing temperature and humidity zones in the atmosphere, such that individual snowflakes differ in detail from one another, but may be categorized in eight broad classifications and at least 80 individual variants.
