As the air temperature increases, with no addition of water vapor to the air, the relative humidity will:

  1. Remain the same

  2. Increase

  3. Decrease

  4. Increase until it becomes equal to the dew point temperature
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Relative humidity is inversely related to temperature when the amount of water vapor is constant. As temperature increases, the capacity of the air to hold water vapor increases, so the ratio (relative humidity) decreases.

Which of the following will increase in a rising parcel of air?

  1. Saturation vapor pressure

  2. Relative humidity

  3. Mixing ratio

  4. Air temperature
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

As a parcel of air rises, it expands and cools due to decreasing atmospheric pressure. Because the capacity of air to hold water vapor decreases as temperature drops, the relative humidity increases.

The density of water vapor in a given parcel of air is expressed by the:

  1. Absolute humidity

  2. Relative humidity

  3. Mixing ratio

  4. Specific humidity
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Absolute humidity is defined as the mass of water vapor in a given volume of air. It is a direct measure of the density of water vapor.

If the air temperature remains constant, evaporating water into the air will _____________ the dew point and ___________ the relative humidity.

  1. Increase, increase

  2. Increase, decrease

  3. Decrease, increase

  4. Decrease, decrease
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Evaporating water into air adds water vapor, which increases the dew point. Since the temperature is constant, the increase in water vapor content raises the relative humidity.

Almost all of the earth's weather occurs in the:

  1. Exosphere

  2. Stratosphere

  3. Mesosphere

  4. Troposphere
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The troposphere is the lowest layer of the atmosphere where most clouds form and weather phenomena occur. It contains the vast majority of the atmosphere's water vapor.

Which of the following weather elements always decreases as we climb upward in the atmosphere?

  1. Wind

  2. Temperature

  3. Pressure

  4. Moisture
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Atmospheric pressure is the weight of the air column above a point. As you climb higher, there is less air above you, so the pressure must decrease.

Humidity influences corrosive action of

  1. Air pollutants

  2. Water Pollutants

  3. Solid material

  4. All of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Humidity, specifically the presence of water vapor, accelerates the oxidation process of metals and reacts with air pollutants to form corrosive acids, which damage materials.

The time of day when the relative humidity reaches a maximum value is usually:

  1. At the time when the air temperature is highest

  2. In the middle of the afternoon

  3. At the time when the air temperature is lowest

  4. Just before sunrise
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Relative humidity is inversely related to temperature. Since the air temperature is usually lowest just before sunrise, the relative humidity reaches its maximum value at that time.

Suppose saturated polar air has an air temperature and dew point of $-10^{o}C$, and unsaturated desert air has an air temperature of $35^{o}C$ and a dew point of $10^{o}C$. The desert air contains ____________ water vapor and has a ____________ relative humidity than the polar air.

  1. More, lower

  2. More, higher

  3. Less, lower

  4. Less, higher
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The desert air has a dew point of 10C, while the polar air has a dew point of -10C. Since dew point is a measure of absolute water vapor content, the desert air has more water vapor. However, because the desert air is much warmer, its capacity to hold water is much higher, resulting in a lower relative humidity.

The temperature scale where 0o represents freezing and $100^{o}$ boiling :

  1. Fahrenheit

  2. Celsius

  3. Kelvin

  4. Absolute
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Celsius scale is defined by the freezing point of water at 0 degrees and the boiling point at 100 degrees at standard atmospheric pressure.
