Question

The stability of any object is a description of the way it ________.

            a.         sits

            b.         moves

            c.         reacts to good news

            d.         reacts to bad news

            e.         reacts to being disturbed

Air that is rising is ________ due to ________.

            a.         warming, expansion

            b.         cooling, expansion

            c.         cooling, compression

            d.         warming, compression

Which of the following is the best indicator of the actual amount of water vapor in the air?

            a.         saturation vapor pressure

            b.         percentage of sky covered by clouds

            c.         relative humidity

            d.         station pressure

            e.         vapor pressure

Which of the following does not help to explain why some of the largest diurnal ranges occur in deserts?

            a.         Few clouds mean that little solar radiation is reflected during the day.

            b.         Dry soil means that little solar radiation is used to evaporate water.

            c.         Dry air at night promotes the loss of infrared radiation to space.

            d.         Clear skies at night allow the atmosphere to absorb more of the earth's infrared radiation.

The primary reason that summers are warmer than winters in the mid-latitudes of the Northern Hemisphere is that ________.

            a.         the sun is higher in the sky so mid-latitudes receive more direct solar radiation

            b.         there are more hours of daylight during the summer

            c.         the earth is closest to the sun in July

            d.         All of the above are correct.

            e.         Only a and b are correct.

________ Law states that the amount of energy emitted by an object (per unit area) is proportional to the object's temperature raised to the ________ power.

            a.         Wien's, 2nd              

            b.         The Stefan-Boltzmann, 2nd

            c.         The Stefan-Boltzmann, 4th                       

            d.         Wien's, 4th

If an object absorbs more energy than it emits (and everything else remains constant), the object's temperature _________.

            a.         remains constant                

            b.         increases

            c.         decreases                             

            d.         varies randomly

Explanation / Answer

The stability of any object is a description of the way it ________.

                     e.         reacts to being disturbed

Air that is rising is ________ due to ________.

                      b.         cooling, expansion

Which of the following is the best indicator of the actual amount of water vapor in the air?

                    c.         relative humidity

Which of the following does not help to explain why some of the largest diurnal ranges occur in deserts?

                      d.         Clear skies at night allow the atmosphere to absorb more of the earth's infrared radiation

Note: A clear day will have a larger diurnal variation because, during the day, more radiation will reach the surface to create a high maximum temperature. At night, more radiation escapes into the atmosphere (and space) to produce a lower minimum temperature.
