- Snow is formed by the crystallization of water and since all water molecules have six sides, so do all snowflakes.
- On average an inch of rain can become one foot of snow.
- There are 7 major snowflake shapes: tubes, stars, hexagonal plates, ridged arm stars, hexagonal columns, needles, and irregular.
- In 1755 the red dust from the Sahara desert caused red snow to fall over Europe when the dust became condensation nuclei for flakes.
- Fluffy (powdery) snow which falls at very low temperatures can be up to 95% air, while warmer temperature will produce very wet heavy flakes.
- An average snowflake is made up of 180 billion water molecules.
