Stratus clouds are typically puffy and form by convection.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Stratus clouds are characterized by their uniform, layered appearance and typically form through widespread lifting or cooling, not through localized convection (which produces puffy cumulus clouds).

When a liquid thermometer is held in direct sunlight,

  1. It will accurately measure the air temperature

  2. It will measure a much higher temperature than that of the air

  3. It will measure a much lower temperature than that of the air

  4. It will measure the temperature of the sun rather than the air
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When a thermometer is in direct sunlight, it absorbs solar radiation, causing the liquid inside to expand more than it would from the air temperature alone, leading to an artificially high reading.

A change of one degree on the Celsius scale is _____________ a change of one degree on the Fahrenheit scale.

  1. Equal to

  2. Larger than

  3. Smaller than

  4. Is in the opposite direction of
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A change of 1 degree Celsius is equivalent to a change of 1.8 degrees Fahrenheit. Therefore, a 1-degree change on the Celsius scale is larger than a 1-degree change on the Fahrenheit scale.

The atmosphere near the earth's surface is "heated from below." Which of the following does not significantly contribute to this heating?

  1. Conduction of heat upward from a hot surface

  2. Convection from a hot surface

  3. Absorption of infrared energy that has been radiated from the surface

  4. Heat energy from the earth's interior
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The atmosphere is primarily heated from the surface upward via conduction, convection, and radiation. Heat from the Earth's interior (geothermal heat) is negligible compared to solar heating at the surface.

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.
