What is the relationship between altitude and air density within the Earth's atmosphere?
- A.
As altitude increases, air density decreases
- B.
As altitude increases, air density increases
- C.
As altitude increases, air density remains the same
- D.
There is no relationship between altitude and air density with the Earth's atmosphere
Correct Answer
A. As altitude increases, air density decreasesExplanation
As altitude increases, the air density decreases because the atmosphere becomes less dense at higher altitudes. This is because the pressure decreases with increasing altitude, which leads to a decrease in the number of air molecules in a given volume of space. Therefore, there is less mass of air per unit volume, resulting in lower air density at higher altitudes.Rate this question:

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.
Morning 1
- B.
Morning 2
- C.
Morning 3
- D.
Morning 4
- E.
Both 3 and 4
Correct Answer
E. Both 3 and 4Explanation
Both Morning 3 and Morning 4 would most likely have fog. This is because the dew point temperature is equal to or very close to the actual temperature in both mornings. When the dew point temperature and the actual temperature are close, it indicates that the air is almost saturated with moisture, which increases the likelihood of fog formation.Rate this question:
-
- 11.
What is the relative humidity when the air temperature is at the dew point?
- A.
50 percent
- B.
100 percent
- C.
10 percent
- D.
20 percent
Correct Answer
B. 100 percentExplanation
When the air temperature is at the dew point, it means that the air is saturated with moisture and cannot hold any more water vapor. At this point, the relative humidity is at its maximum, which is 100 percent. This means that the air is holding the maximum amount of moisture it can at that temperature, resulting in a relative humidity of 100 percent.Rate this question:

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.
Snowy hillside
- C.
Desert landscape
- D.
Both A and C
Correct Answer
D. Both A and CExplanation
Both a paved road on a sunny day and a desert landscape would cause the air above the surface to heat the fastest. Paved roads and desert landscapes are known to have low albedo, meaning they reflect less sunlight and absorb more of it. This absorption of sunlight leads to a rapid increase in surface temperature, which in turn heats up the air above it. On the other hand, a snowy hillside would have a high albedo, reflecting most of the sunlight and preventing the surface from heating up quickly.Rate this question:

What would you expect to happen to the air pressure as a storm approaches?
- A.
It would remain steady
- B.
It would increase
- C.
It would decrease
- D.
It would increase, then decrease
Correct Answer
C. It would decreaseExplanation
As a storm approaches, the air pressure would decrease. This is because storms are associated with low-pressure systems. As the storm system moves closer, it displaces the surrounding air, causing the air pressure to drop. This decrease in air pressure is often an indication of an impending storm and can be observed through changes in barometric pressure.Rate this question:
