In summer, humid regions typically have _____ daily temperature ranges and _____ maximum temperatures than drier regions.
An important reason for the large daily temperature range over deserts is:
there is little water vapor in the air to absorb and re-radiate infrared radiation
If the temperature is 25C and the relative humidity is 50% approximately what is, e the actual vapor pressure?
Over the earth as a whole, on woul expect to observe the smallest variation in temperature from day to day and from month to month:
on a small island near then equator
If the temperature is 20C and the actual vapor pressure, e, us 10mb what is the relative humidity?
The lowest temperature that can be attained by evaporating water into the air is known as the
At 40F, the atmosphere is saturated with water vapor. If the air temperature increases to 60F, with no addition or removal of water vapor, one may conclude that the dew point is about:
As the air tempwerature increases, with no addition of water vapor to the air, the dew point will:
remain the same
The temperature to which the air must be cooled in order to become saturated is the:
dew point temperature
Suppose saturated polar air has an air temperature and dew point of -10C, and unsaturated desert air has an air temperature of 25C and a dew point of 10C. The desert air contains _____ water vapor and has a ____ relative humidity than the polar air
If the air temperature increased, with no addition or removal of water vapor, the actual avpor pressure would:
stay the same
Which of the following is not a reason why water warms and cools much more slowly than land?
it takes more heat to raise the temperature of a given amount of soil 1C than it does to raise the temperature of water 1C
If very cold air is brought indoors anjd warmed with no change in its moisture content, the saturation vapor pressure of this air will ____ and the relative humidity of this air will ____.
The percentage of water vapor present in the air compared to that required for saturation is the:
At which time of day is the relative humidity normally at a minimum?
when the air temperature is highest
If the air temperature remains constant, evaporating water into the air will ____ the dew point and ____ the relative humidity.
