QuestionAnswer
The frequency of an electromagnetic wave is ______ proportional to its wavelength. inversely
______ is the distance between successive troughs and crests. Wavelength
All of the following types of electromagnetic radiation have wavelengths longer than that of visible light with the exception of ultraviolet radiation
All of the following types of electromagnetic radiation have wavelengths shorter than that of visible light with the exception of radio waves
Violet has the ______ wavelength in the visible electromagnetic spectrum. shortest
Ultraviolet radiation, gamma rays, and X-rays have frequencies ______that of visible light and infrared radiation. higher than
Solar radiation that reaches Earth's surface consists of All of the above.
______ is (are) partially blocked by ozone in the stratosphere. Ultraviolet radiation
According to Wien's displacement law, which one of the following objects emits its most intense electromagnetic energy at the shortest wavelength? the Sun
Generally, as the temperature of a radiating surface decreases, the wavelength at which radiation from the surface is most intense will lengthen.
If the temperature of the Sun were to ______, the wavelength at which solar radiation is most intense would decrease. increase
Solar radiation is most intense at a shorter wavelength than terrestrial infrared radiation.
The ultimate source of solar radiation is nuclear fusion in the Sun.
Today, the solar altitude is at a maximum around noon
Earth is closest to the Sun during the Northern Hemisphere winter.
Earth is closest to the Sun in January
During summer in the Northern Hemisphere, the number of hours of daylight is ______ the number of hours of darkness. greater than
During winter in the ______ Hemisphere, the number of hours of daylight is less then the number of hours of darkness. Southern
Exactly one-half of the surface area of the Earth is in sunlight during any day of the year.
On the first day of summer in the Southern Hemisphere, the noon Sun has an altitude of 90 degrees where? Tropic of Capricorn
Except right at the poles, nights are everywhere about 12 hours long when? equinoxes
At the equinoxes, the noon Sun has an altitude of 90 degrees at the equator
The period of daylight at any point along the equator is essentially the same throughout the year.
Earth's solar constant is actually variable.
As solar radiation travels through the atmosphere, a portion of that radiation is All of the above are correct.
Through absorption, solar radiation is converted to heat energy
The layer of the atmosphere that contains the ozone shield is the stratosphere
The principal threat to the ozone shield is (are) chlorofluorocarbons (CFCs).
A thinner ozone shield would likely mean All of the above are correct.
Formation and dissociation of ozone in Earth's atmosphere is related to the Both of the above are correct.
Which one of the following surfaces has the lowest albedo for visible solar radiation? black asphalt
Which one of the following surfaces has the highest albedo for visible solar radiation? fresh snow
Which one of the following surfaces absorbs the highest percentage of incident solar radiation at noon? the ocean
The average albedo of the ocean is less than 10 percent.
On a clear day, the albedo of the sea surface is lowest at noon
The Moon's planetary albedo is __________ the albedo of the Earth. less than
The surface of Earth is absorbing solar radiation. If more solar radiation is absorbed than emitted, then the temperature of Earth's surface will rise
The principal absorber(s) of the solar radiation that is intercepted by the Earth-atmosphere system is (are) ocean water
Earth's planetary albedo is about ______ percent. 31
Earth's surface and atmosphere emit primarily what type of electromagnetic radiation? infrared
The greenhouse effect is primarily the consequence of atmospheric water vapor
At night, air temperatures near Earth's surface tend to be lowest when the sky is clear
Clouds, carbon dioxide, water vapor, and methane strongly ______ infrared radiation. absorb
The chief reason for the upward trend in atmospheric carbon dioxide since the mid-1800s is (are) burning of fossil fuels
A gas that absorbs within the so-called atmospheric windows: Both of the above contribute.
A doubling of the absolute temperature of the Sun's surface would cause the amount of solar energy reaching the Earth to be sixteen times the amount it now receives.
Compared to the rest of the 20th century, the global mean annual temperature during the decade of the 1990s was relatively high
An infrared radiometer flown onboard a weather satellite is used to measure cloud surface temperatures.
