Question 2

Correct Answer:

Verified

As opposed to actual vapor pressure, which indicates the air's total water vapor content, saturation vapor pressure describes how much water is vapor is necessary to make the air saturated (when total evaporation equals total condensation and no net loss or gain of vapor molecules occurs) at any given temperature. In other words, saturation vapor pressure is the pressure that the water vapor molecules would exert if the air were saturated with vapor at a given temperature. When air temperature increases, it takes more water vapor to saturate the air.

Thin, wispy clouds blown by high winds into long streamers, called mare's tails, are ____.
