Exam 7: Water and Atmospheric Moisture

The portion of air pressure exerted by water vapor is the

Less than 0.03 percent of Earth's water is stored in the atmosphere.

The smaller the difference in temperature between the wet bulb and dry bulb on a sling psychrometer, the ________ the air is and the ________.

The point where saturation begins in a rising air parcel is

Relative humidity is the mass of water vapor per mass of air.

Specific humidity is the mass of water vapor (g) per mass of air (kg).

Which of the following phase changes of water is incorrectly matched?

Which of the following is correctly matched.

An ascending parcel of air tends to cool by expansion, while a descending parcel of air tends to heat by compression.

High altitude wispy clouds made of ice crystals are classed as

Discuss how humans are affected by atmospheric water vapor and how humans can affect atmospheric water vapor.

Which of the following is incorrect?

Assuming the amount of water vapor remains constant, a temperature increase will ________ the specific humidity.

The condensation process requires

The dry adiabatic rate (DAR) applies to a parcel of air that is saturated.

If a parcel of air is cooled and the amount of water vapor remained constant, its relative humidity would rise.

Evaporation is a warming process.

The greater the difference in temperature between the wet bulb and dry bulb on a sling psychrometer, the ________ the air is and the ________ the relative humidity.

As temperature increases, the amount of energy available for evaporation

What is atmospheric stability? What are adiabatic processes and how they are related to atmospheric stability?
