A heat transfer process in the atmosphere that depends upon the movement of air is:
Which of the following helps to explain why even though northern latitudes experience 24 hours of sunlight on June 22, they are not warmer than latitudes further south?
all of the above, 1: solar energy is spread over a larger area in northern latitudes, 2: some of the sun's energy is reflected by snow and ice in the northern latitudes, 3: increased cloud cover reflects solar energy in the northern latitudes, 4: solar energy is used to melt frozen soil in the northern latitudes
This is released as sensible heat during the formation of clouds
latent heat
Where are the days and nights of equal length all year long?
at the Equator
Th earth's radiation is often referred to as ____ radiation, while the sun's radiation is often referred to as ______ radiation.
longwave, shortwave
Which latitude below would experience the fewest hours of daylight on Dec. 22?
60 N
The combined albedo of the earth and the atmosphere is approximately:
Which of the following is an incorrect association?
black body - selective absorber
Which of the following has the highest albedo?
The albedo of the earth's surface is only about 4%, yet the combined albedo of the earth and the atmosphere is about 30%. Which set of conditions below best explains why this is so?
high albedo of clouds, low albedo of water
The horizontal transport of any atmospheric property by the wind is called:
Clouds ______ infrared radiation and ______ visible radiation.
absorb, reflect

Most of the radiation emitted by a human body is in the form of:
infrared radiation and is invisible
The sun emits a maximum amount of radiation at wavelengths near____, while the earth emits maximum radiation near wavelengths of ____.
0,5 micrometers, 10 micrometers
One micrometer is a unit of length equal to:

The latitude at which there is a yearly balance between incoming and outgoing radiation is about:
37 degrees
If the earth's average surface temperature were to increase, the amount of radiation emitted from the earth's surface would ____ and the wavelength of peak emission would shift toward _____ wavelengths.
increase, shorter
The sun emits its greatest intensity of radiation in:
the visible portion of the spectrum
Which greenhouse gas absorbs both in the infrared an the ultraviolet radiation?
The sun is directlty overhead at Mexico City (latitude 19N):
twice a year#
