rain because if its above freezing then it wont be snow or freezing rain because they would freeze below freezing and not above freezing:)

Hail?
When the temperature drops the less water vapor in the air
The dew point refers to water droplets forming on the grass as the temperature drops. This is actually a condensation process.
In the troposphere, the temperature drops. In the stratosphere (layer above the troposphere) it increases with elevation. In the mesosphere, temperature drops again with elevation. In the theromosphere, it goes up again (to nearly stellar surface temperatures).
Water drops that fall when the temperature is below freezing, fall as SNOW . Water drops that fall when the temperature is above freezing fall as RAIN .
rain
it is snow or feezing rain i belive
Fresh water (for instance) will freeze and turn to ice when the temperature drops below freezing point. The ice will thaw (melt back into water) when the temperature rises above freezing point.
it drops
Snow
Hail?
Depending on the temperature, water drops that fall when the temperature is below freezing can become sleet, ice, or snow.
No, dew is liquid water and it forms when the air temperature drops sufficiently that the air can no longer hold all its water vapour. This must be above freezing point. Of course the same argument applies when the temperature does drop below zero, but then we get ice crystals instead of water drops, and we call it frost.
The usual term is "sleet".
Usually the humidity is extremely low when the temperature drops below freezing, because almost all of the water is frozen out of the air.
This is simply because salt water has a lower freezing temperature than fresh water - as the percetage of salt to water increases the freezing temperature drops. As ice has a lower density than water, less salt is required per volume (as there is less water per volume). For every 1% of salinity the freezing point drops about 1/2 a degree (although it is not linear).
