Side ASide B
On a calm night, the relative humidity a few inches above grass is lower than it is a few feet above the grass.
False
The capacity of air to hold water vapor is temperature dependent.
True
Clear skies are associated with substdence or sinking motion.
True
Adiabatic temperature changes refer to parcels of air that rise or sink.
True
The circulation of water vapor through the atmosphere is very small compared to the Earth's rivers systems.
False
The environmental lapse rate is usually the same as the dry adiabatic rate.
False
Moisture in clouds is considered to be water vapor when making humidity calculations.  
False
The formation of hoar frost is an example of deposition.
True
The average annual precipitation for the Earth is equal to the annual amount of evaporated water.
True
High humidity in summer makes people uncomfortable because high humidity slows perspiration evaporation.
True
When air sinks, it is compressed and warmed.
True
If the temperature remains unchanged and the mixing ratio drops, the relative humidity will increase.
False
Relative humidity gives a measurement of the amount of water in the air, and is usually measured in grams per cubic meter.
False
An area that is very cold in winter will probably also have a relatively dry winter.
True
When discussing the water vapor in the air, meteorologists prefer to use absolute humidity rather than mixing ratio.
False
More water is evaporated from the oceans than is returned to the oceans by precipitation.
True
For a given mass of rising air, the dry adiabatic rate will always be higher than the wet adiabatic rate.
True
If the mixing ratio remains unchanged and the temperature drops, the relative humidity will increase.
True
The saturation vapor pressure is independent of temperature.
False
The absolute humidity of the air is expressed as a percent.
False
