Which of the following provides a measure of the average speed of air molecules? |
temperature |
|
|
If the temperature of the air is said to be at absolute zero, one might conclude that |
the molecules contain a minimum amount of energy |
|
|
When water changes from a liquid to a vapor, we call this process |
evaporation |
|
|
This is released as sensible heat during the formation of clouds |
latent heat |
|
|
The processes of condensation and freezing |
both release sensible heat into the environment |
|
|
the horizontal transport of any atmospheric property by the wind is called |
advection |
|
|
The amount of heat energy required to bring about a small change in temperature is called |
specific heat |
|
|
The temperature of a rising air parcel |
always cools due to expansion |
|
|
The proper order from shortest to longest wavelengths is |
ultraviolet, visible, infrared |
|
|
How do red and blue lights differ? |
the wavelength of red light is longer |
|
|
Solar radiation reaches the earth's surface as |
ultraviolet, visible and infrared radiation |
|
|
Often before sunrise on a clear, calm, cold morning, ice (frost) can be seen on the tops of parked cars, even when the air temperature is above freezing This condition happens because the tops of the cars are cooling by |
radiation |
|
|
If you want to keep an object cool while exposed to direct sunlight, |
wrap it in aluminum foil with the shiny side facing outward |
|
|
Which of the following has a wavelength shorter than that of violet light? |
ultraviolet radiation |
|
|
At which temperature would the earth be radiating energy at the greatest rate or intensity? |
105 F |
|
|
the sun emits its greatest intensity of radiation in |
The visible portion of the spectrum |
|
|
The earth emits radiation with greatest intensity at |
infrared wavelengths |
|
|
Which principle best describes why holes develop in snow around tree trunks |
Snow is a good absorber of infrared energy |
|
|
Without the atmospheric greenhouse effect, the average surface temperature would be |
lower than at present |
|
|
The atmospheric greenhouse effect is produced mainly by the |
absorption and re-emission of infrared radiation by the atmosphere |
|
|
Suppose last night was clear and calm. Tonight low clouds will be present. From this you would conclude that tonight's minimum temperature will be |
higher than last night's minimum temperature |
|
|
The combined albedo of the earth and the atmosphere is approximately ___ percent. |
30 |
|
|
The albedo of the moon is 7 percent. This means that |
7 percent striking the moon is reflected |
|
|
if the present concentration of CO2 doubles in 100 years, and climate models predict that for the earth's average temperature to rise 5 C, what gas must also increase in concentration? |
water vapor |
|
|
If the amount of energy lost by the earth to space each year were not approximately equal to that received, |
the atmosphere's average temperature would change |
|
|
The earth's radiative equilibrium temperature is |
the temperature at which the earth is absorbing solar radiation and emitting infrared radiation at equal rates |
|
|
Perspiration cools the body by |
latent heat transfer |
|
|
The aurora are seen |
in both the Northern and Southern Hemispheres at high latitudes |
|
|
Supposed you are outside in very cold temperatures, wearing a winter coat that is quite effective at keeping you warm. Which of the following is true? |
Your body generates the heat that keeps you warm AND the coat prevents your body's heat from escaping to the surrounding air |
|
|
Sunlight passes through a thicker portion of the atmosphere at |
both sunrise and sunset |
