"A good absorber of a given wavelength is also a good emitter of that wavelength." This is a statement of:
A change of one degree on the Celsius scale is ________ a change of one degree on the Fahrenheit scale.
According to Wein's displacement law, the wavelength at which maximum radiation occurs is:
inversely proportional to the temperature.
An increase in albedo would be accompanied by a ______ in radiative equilibrium temperature.
Charged particles from the sun that travel through space at high speeds are called,
plasma, or solar winds/flares.
Electromagnetic radiation with wavelengths between 0.4 and 0.7 micrometers is called:
Heat is energy in the process of being transferred from:
one object to another because of the difference in temperature between them.
If the amount of energy lost by the earth to space each year were not approximately equal to that received,
the average surface temperature would change.
If the average temperature of the sun increased, the wavelength of peak solar emission would:
If the 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.
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.
If you want to keep an object cool while exposed to direct sunlight,
wrap it in aluminum foil with the shiny side facing outward.
In the earth's upper atmosphere, visible light given off by excited atoms and molecules produces:
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:
On average, about what percentage of solar energy that strikes the outer atmosphere eventually reachers the earth's surface?
Solar radiation reaches the earth's surface as:
visible light (but also ultraviolet light and infrared light).
Suppose you are outside in very cold temperatures, wearing a winter coat that is effective at keeping you warm. Which of the following is true?
The coat is the source of heat that keeps you warm, the coat prevents your body's heat from escaping to the surrounding
The albedo of the earth's surface is only about 4 percent, yet the combined albedo of the earth and the atmosphere is about 30 percent. Which set of conditions BEST explains why?
High albedo of clouds, low albedo of water.
The amount of heat energy required to bring about a small change in temperature is called the:
The atmospheric greenhouse effect is produced mainly by the:
absorption and re-emission of infrared radiation by the atmosphere.
The blueness of the sky is mainly due to:
the scattering of shorter wavelengths of sunlight by air molecules.
The cold feeling that you experience after leaving a swimming pool on a hot, dry, summer day represents heat transport by:
The earth's radiation is often referred to as ______ radiation, while the sun's radiation is often referred to as ______ radiation.
The earth's radiative equilibrium temperature is:
the temperature at which the earth is absorbing solar radiation and emitting infrared radiation at equal rates.
The sun emits a maximum amount of radiation at wavelengths near ______, while the the earth emits maximum radiation near wavelengths of ______.
0.5 micrometers (visible light), 10 micrometers (infrared)
Which of the following determine the kind (wavelength) and amount of radiation that an object emits?
