1. Dry snow
2. Wet snow
3. Loose snow
4. Compacted snow
5. Slush
6. Sleet
Thank you very much!

Dry snow. If you try and make a snow ball, it falls apart. Not sticky.
Wet snow. Success! You can make a snowball. It's sticky and a right bugga to shift.
Loose snow. Hmm. Like dry snow I'd have thought.
Compacted snow. As it says on the tin. It's been squashed together already.
You can operate on it.
Slush. A combo of snow, ice and water. Quite draggy when trying to take off. Slippery as any thing when taxiing.
This is a good reference. Skybrary
Not much on snow though.

Slush is water saturated with snow, which spatters when firmly stepped on. Slush
forms at temperatures around 5°C and has a density of approximately 0.85 kg/litre.
Wet snow is snow that will, if compacted by hand, stick together and tend to form a
snowball. Wet snow has a density of approximately 0.4 kg/litre, therefore 12mm
WED equals 30mm depth.
Dry snow is snow which can be blown if loose, or which will, if compacted by hand,
fall apart upon release. Dry snow has a density of 0.2 kg/litre, therefore 12mm WED
equals 60mm depth.
