Answer 4

Heat index

Question 5

A) freezing & melting B) sublimation & deposition
C) evaporation & condensation D) none of the above

Answer 5

B) sublimation & deposition

Question 6

When is ‘Saturation’ considered to be in effect?

Answer 6

Saturation occurs when the condensation rate equals the evaporation rate.

Question 7

Air that contains as much water as it can hold is considered:

Answer 7

Saturated

Question 8

A) melting
B) deposition
C) freezing
D) condensation

Answer 8

B) deposition

Question 9

Saturation vapor pressure is dependent upon what variable?

Answer 9

Temperature

Question 10

The number of grams of water vapor in a cubic meter of air is called the:

Answer 10

Absolute humidity

Question 11

Relative humidity can change substantially during the course of:

Answer 11

1 day

Question 12

When the relative humidity is 100%:

Answer 12

.

Question 13

As temperature increases, the relative humidity will be generally:

Answer 13

erratic

Question 14

The existence of water vapor can have what effect:
A) increase in atmospheric pressure
B) decrease in atmospheric pressure
C) cause winds to be stronger

Answer 14

A) increase in atmospheric pressure

Question 15

What is probably the most effective index of water vapor content?

Answer 15

The most familiar measure of water vapor content is Relative Humidity.

Question 16

In what season would steam fog most likely occur?

Answer 16

Late fall & early winter

Question 17

What are the three processes for saturating air with water vapor?

Answer 17

1. Adding water vapor to the air
2. Mixing cold air with the warm, moist air
3. Lowering the temperature to the dew point

Question 18

What does the term ‘supersaturation’ describe?

Answer 18

When the atmosphere contains more moisture than theoretically possible.

Question 19

Water that is below 0 degrees centigrade is called:

Answer 19

Supercooled water

Question 20

Diabatic processes:
A) Add or remove energy from a system
B) Occur when rising air expands and cools w/o gaining or losing energy
C) do not always conform to the 2nd Law of Thermodynamics

Answer 20

A) Add or remove energy from a system

Question 21

Adiabatic processes:
A) are relatively uncommon in the atmosphere
B) often involve changes in both temperature and pressure
C) occur with the addition or loss of energy

Answer 21

B) often involve changes in both temperature and pressure

Question 22

A parcel of rising air is least likely to:
A) contract
B) cool
C) reach the lifting condensation level
D) reach an area of lower pressure

Answer 22

A) Contract

Question 23

Once a parcel of air rises above the lifting condensation level, the rate of cooling slows because:

Answer 23

Latent heat is released when water vapor condenses

Question 24

What types of fog are NOT the result of air cooling to the dew point?

Answer 24

Precipitation Fog and Steam Fog

Question 25

The difference between fog and a cloud is:

Answer 25

Nothing. Clouds and fog are a matter of observational perspective.
