Moisture and Atmospheric Stability
True or False


Select the correct response to each of the following true/false questions.

1 .       The change in the air's temperature with altitude is called the environmental lapse rate. 

 
 


2 .       The highest relative humidity of the day is most likely to occur in the mid-afternoon. 

 
 


3 .       In general, temperature inversions produce unstable atmospheric conditions. 

 
 


4 .       Vapor pressure is that part of the total atmospheric pressure attributable to its water vapor content. 

 
 


5 .       The circulation of Earth's water supply among the oceans, atmosphere, and continents is referred to as the evapotranspiration cycle. 

 
 


6 .       The stability of air is determined by measuring the temperature of the atmosphere at various heights (environmental lapse rate). 

 
 


7 .       The Great Basin, Gobi, and Patagonia Deserts are all examples of rain shadow deserts. 

 
 


8 .       Heat energy that does not produce a temperature change but becomes stored in the matter is called latent heat. 

 
 


9 .       In general, subsidence stabilizes the air. 

 
 


10 .       Assuming no additional water vapor is added to the air, increasing the air's temperature will increase the relative humidity. 

 
 


11 .       The dew point is the temperature at which liquid water becomes water vapor. 

 
 


12 .       Stable air resists vertical movement. 

 
 


13 .       Relative humidity is a ratio of the air's actual water vapor content compared with the amount of water vapor required for saturation at that temperature (and pressure).
