Our seasons are caused by:

  1. The changing distance between the earth and the sun

  2. The angle at which sunlight reaches the earth

  3. The length of the daylight hours

  4. Only (b) and (c) are correct
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Seasons are primarily caused by the tilt of the Earth's axis, which changes the angle of sunlight and the duration of daylight throughout the year as the Earth orbits the Sun.

Which statement(s) below is/are correct?

  1. Valleys are more susceptible to radiation fog than hill tops

  2. Without the summer fog along the coast of California, redwoods would not grow well there

  3. Fog can be composed of ice crystals

  4. All of the above are correct
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All listed statements are correct: cold air drains into valleys (radiation fog), coastal fog provides essential moisture for redwoods, and ice fog occurs in extremely cold conditions.

If very cold air is brought indoors and warmed with no change in its moisture content, the saturation vapor pressure of this air will __________ and the relative humidity of this air will ___________ .

  1. Increase, increase

  2. Decrease, decrease

  3. Increase, decrease

  4. Decrease, increase
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Warming air increases its capacity to hold water vapor (saturation vapor pressure increases). If the actual moisture content remains constant, the ratio of actual to saturation vapor pressure (relative humidity) decreases.

At what time of day is the relative humidity normally at a minimum?

  1. When the air temperature is highest

  2. Just before sunrise

  3. About midnight

  4. When the air temperature is lowest
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Relative humidity is inversely related to temperature. When the temperature is at its daily maximum, the air's capacity to hold water is highest, resulting in the lowest relative humidity.

The instrument that measures temperature, pressure, and humidity at various altitudes in the atmosphere:

  1. Barograph

  2. Radiosonde

  3. Aneroid barometer

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

A radiosonde is a weather instrument carried by a balloon that measures and transmits vertical profiles of temperature, pressure, and humidity as it ascends through the atmosphere.

When clouds are viewed near the horizon, the individual cloud elements usually:

  1. Appear closer together than is actually the case

  2. Appear farther apart than is actually the case

  3. Appear lighter in color than is actually the case

  4. Appear to have more vertical development than is actually the case
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Due to perspective, objects near the horizon appear compressed. Cloud elements at a distance appear to be closer together than they actually are because of the viewing angle.
