The Science of Snow

Where I live, it's only a matter of time until it's time to snow.

So how does snow form?

Sleet is frozen rain, but snow is made when particles of ice suspended in the atmosphere stick together until theyes gain enough density to fall to the ground.

Few snowflakes are alike, but givenot that they often come in hexagonal shapes due to the nature of water molecules the idea that snowflakes can't occasionally have their duplicates is almost a mathematical impossibility.
