Most of the radiation emitted by a human body is in the form of:
infrared radiation and is invisible
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:
A temperature of 27° C would be equal to what temperature on the Kelvin scale?
When water changes from a liquid to a vapor, we call this process:
The processes of condensation and freezing:
*Not- do not affect the temperature of their surroundings
The atmosphere near the earth's surface is "heated from below." Which of the following is not responsible for the heating?
heat energy from the earth's interior
At night, low clouds:
*Not- are often caused by the atmospheric greenhouse effect *Not- have no effect on the atmospheric greenhouse effect
The horizontal transport of any atmospheric property by the wind is called:
Which of the following statements is not correct?
*Not- calm,cloudy nights are usually warmer than calm, clear nights *Not- each year the earth's surface radiates away more energy than it receives from the sun
The blueness of the sky is mainly due to:
the scattering of sunlight by air molecules
Which of the following is known primarily as a selective absorber of ultraviolet radiation?
The change of state of ice into water vapor is known as:
An increase in albedo would be accompanied by __ in radiative equilibrium temperature.
The cold feeling that you experience after leaving a swimming pool on a hot, dry, summer day represents heat transport by:
The atmospheric greenhouse effect is produced mainly by the:
absorption and re-emission of infrared radiation by the atmosphere
The heat energy released when water vapor changes to a liquid state is called:
latent heat of condensation
"A good absorber of a given wavelength of radiation is also a good emitter of that wavelength." This is a statement of:
