why isnt frost & dew a from of precipation?

Question

&&& some other questions:

2) how do temp. & moisture content affect condensation & evaporation?

3) what affect does changing the temp. of an air sample have on relative humidity?

4) what affect does changing the air temp. have on the condensation level of a cloud?

Answer 1

Frost and dew are not precipitation because they form from the moisture that is already in the air at ground level and does not fall.

2)The higher the temperature, the more rapidly evaporation will occur.

3)If you increase the temperature of an air sample, the relative humidity will decrease.

4)The cloud base will form at the altitude where the air temperature equals the dew point.

Answer 2

(1)If you call a weather phenomena as precipitation, it should fall from a height.But frost and dew form over or near the round.So, they cannot be called as precipitation.Frost forms when the air temperature near or over the ground falls below freezing point and dew forms when the air temperature near the ground reaches dew point temperature.
(2)If air temperature comes down to dew point temperature,condensation occurs;otherwise not.If moisture content becomes maximum(100 percent R.H). condensation begins.
If temperature increases, evaporation also increases.Moisture content in the atmosphere becomes more if evaporation is more.
Further,air with higher temperature can hold more moisture(than a cold air).
(3)If the temperature of an air sample is increased (without increasing the moisture content),the relative humidity will fall and vice versa.
(4) If the temperature is decreased to the dew point at a particular height (without decreasing the moisture content),that particular height will become the condensation level.
