Snow is a form of crystalised percipitation, these ice crystals are formed in a prism shape. As the crystals are formed, they fall from the sky as
- Snow crystals -Made from condensing water vapour in the air, usually very small in size largest is a few millimetres in diameter.
- Snow flakes - Collection of snow crystals all bound together loosely, can be as large as 10 cm across.
- Rime - Small water droplets that freeze on whatever they hit. ( usually during fog )
- Hail - solid chuncks of ice.
The temperature must drop to a cold state before any snowfall occurs. Snowfall is incredibly hard to predict. It is also very hard to measure as it melts very quickly.
