As altitude increases, air density decreases
B. 
As altitude increases, air density increases
C.

7.
Which layer of the atmosphere is best described by the following:
layer of the atmosphere where weather occurs, has the highest air pressure and density
A. 
B. 
C. 
D. 
8.
Collection of water on the earth can be in the form of....
A. 
B. 
C. 
D. 
9.
Precipitation includes rain or snow.
10.
As water is heated, it evaporates into the atmosphere. As this water vapor rises into the atmosphere, it can saturate the air with moisture and cause high amounts of humidity. When air has a lot of humidity, dew and even fog can form, depending on the air temperature. The table below shows the temperature and dew point of an area on 4 separate mornings. Use the table to determine which morning(s) would most likely have fog.
Temperature
Dew Point
Morning #1
58°F
55°F
Morning #2
47°F
40°F
Morning #3
61°F
60°F
Morning #4
48°F
48°F
A. 
B. 
C. 
D. 
E. 
11.
What is the relative humidity when the air temperature is at the dew point?
A. 
B. 
C. 
D. 
12.
Different surfaces absorb the sun's energy in different ways. These differences have an influence on the weather. As the surface of Earth heats up, the air above the surface heats up as well. In certain parts of the Earth, air will heat up more quickly than others. Select the the surface (s) that would cause air above the surface to heat the fastest.
A. 
Paved road on a sunny day
B. 
C. 
D. 
13.
What would you expect to happen to the air pressure as a storm approaches?
A. 
B. 
C. 
D. 
It would increase, then decrease
14.
The map below shows the temperatures of surface water in different parts of the world. Read the descriptions below and decide which part of the map the description corresponds to.
A. 
Region 1 has the least amount of energy absorbed
B. 
Region 2 Temperatures will heat up quickly , and will cool faster
C. 
Region 3 Area experiences more evaporation into the atmosphere
D. 
All of the above statements are true
15.

A. 
B. 
C. 
D. 
16.
The greenhouse effect and ozone depletion (holes in ozone layer) are the same thing.
