Kinser --
1. Snow is a result of condensation of water vapor from gas to solid. Snow is never frozen rain, which is sleet or freezing rain.
2. Rain is typically molten snow -- snow that melts in the air as it drops from parts of the atmosphere in which the temperature is below freezing to levels at which the air is above freezing. (Friction may play a role too, but that is slight).
3. Ice and snow may ablate through either liquefaction (melting) or evaporation (sublimation).
4. Although pure water freezes and melts at 0C/32F, salt as in sea water tends to lower the melting point.
As if you were expected to know this.

The ideal subject of totalitarian rule is not the convinced Nazi or the dedicated Communist but instead the people for whom the distinction between fact and fiction, true and false, no longer exists -- Hannah Arendt.
