End of Question 1


Question 2.
The circulation of Earth's water supply among the oceans, atmosphere, and continents is referred to as the evapotranspiration cycle.
   
 
End of Question 2


Question 3.
During the processes of water state changes, ________________________ heat is either absorbed or released.
 
End of Question 3


Question 4.
If the air temperature remains constant, evaporating water into the air will __________ the relative humidity and __________ the dew point.
 
End of Question 4


Question 5.

End of Question 5


Question 6.
Match the term on the left with the correct description on the right.
A matching question presents 5 answer choices and 5 items. The answer choices are lettered A through E. The items are numbered 6.1 through 6.5. Screen readers will read the answer choices first. Then each item will be presented along with a select menu for choosing an answer choice. Using the pull-down menus, match each item in the left column to the corresponding item in the right column.
A the ratio of the air's actual water-vapor content compared with the amount of water vapor required for saturation at that temperature
B mass of water vapor of given volume of air
C the temperature to which a parcel of air would need to be cooled to reach saturation
D mass of water vapor in a unit of air compared to the remaining mass of dry air
E that portion of the total atmospheric pressure attributable to its water-vapor content
 
 
 
 
 
End of Question 6


Question 7.
The dew point is the temperature at which liquid water becomes water vapor.
   
 
End of Question 7


Question 8.
High dew-point temperatures equate with ____________ air, while low dew-point temperatures indicate __________ air.
 
End of Question 8


Question 9.
The relative humidity can be calculated by using a sling psychrometer and noting the difference between the ____________________ and ____________________ readings.
 
End of Question 9


Question 10.
Which one of the following is NOT a mechanism that causes air to rise?
 
End of Question 10


Question 11.
Temperature changes in which heat is neither added nor subtracted are called ___________________ temperature changes.
 
End of Question 11


Question 12.

Question 13.
The dry adiabatic rate is:
 
End of Question 13


Question 14.
A change in the stability of air near the surface is frequently associated with a change in the __________.
 
End of Question 14


Question 15.
The infiltration of surrounding air into a column of vertically moving air is a process called __________.
 
End of Question 15


Question 16.
The change in the air's temperature with altitude is called the environmental lapse rate.
   
 
End of Question 16


Question 17.
In general, subsidence stabilizes the air.
   
 
End of Question 17


Question 18.
Match the term on the left with the description on the right.
A matching question presents 3 answer choices and 3 items. The answer choices are lettered A through C. The items are numbered 18.1 through 18.3. Screen readers will read the answer choices first. Then each item will be presented along with a select menu for choosing an answer choice. Using the pull-down menus, match each item in the left column to the corresponding item in the right column.
A when moist air has an environmental lapse rate between the dry and wet adiabatic rates
B when the environmental lapse rate is greater than the dry adiabatic rate
C when the environmental lapse rate is less than the wet adiabatic rate
 
 
 
End of Question 18
