Ice samples from continental glaciers provide evidence that today's atmosphere contains more carbon dioxide than ancient atmospheres did. This increase concerns scientists because increased carbon dioxide may

a) cause plants to grow very rapidly

b) cause a loss in the amount of radiant energy from the Sun

c) contribute to a gradual warming of the atmosphere

d) contribute to a rapid cooling of the oceans

Deforestation increases the greenhouse effect on Earth because deforestation causes the atmosphere to contain

a) more carbon dioxide, which absorbs infrared radiation

b) less carbon dioxide, which absorbs short-wave radiation

c) more oxygen, which absorbs infrared radiation

d) less oxygen, which absorbs short-wave radiation

The most likely cause of the overall change in the level of carbon dioxide from 1960 to 1990 is an increase in the

a) number of violent storms

b) number of volcanic eruptions

c) use of nuclear power

d) use of fossil fuels

What is the purpose of the clear glass covering of this solar collector?

a) The glass radiates infrared energy.

b) The glass radiates ultraviolet energy.

c) The glass allows short-wave radiation to enter and traps long-wave reradiation.

d) The glass allows long-wave radiation to enter and traps short-wave reradiation.

A gradual increase in atmospheric carbon dioxide would warm Earth’s atmosphere because carbon dioxide is a

a) poor reflector of ultraviolet radiation

b) good reflector of ultraviolet radiation

c) poor absorber of infrared radiation

d) good absorber of infrared radiation

This significant change in CO2 concentration is most likely caused by

a) decreased cloud cover, and is predicted to decrease average global temperatures

b) decreased volcanic activity, and is predicted to increase average global temperatures

c) increased use of fossil fuels, and is predicted to increase average global temperatures

d) increased EI Niño activity, and is predicted to decrease average global temperatures

Which gas is considered a major greenhouse gas?

a) methane

b) hydrogen

c) oxygen

d) nitrogen

Why are carbon dioxide and water vapor called the greenhouse gases?

a) They are found in varying amounts in Earth's atmosphere.

b) They are found in fixed amounts in Earth's bedrock.

c) They are good reflectors of infrared radiation.

d) They are good absorbers of infrared radiation.

Which gas in Earth's upper atmosphere is beneficial to humans because it absorbs large amounts of ultraviolet radiation?

a) water vapor

b) methane

c) nitrogen

d) ozone

What is the primary function of the clear glass of the greenhouse?

a) The glass reduces the amount of insolation entering the greenhouse.

b) The glass allows all wavelengths of radiation to enter and all wavelengths of radiation to escape.

c) The glass allows short wavelengths of radiation to enter, but reduces the amount of long wavelength radiation that escapes.

d) The glass allows long wavelengths of radiation to enter, but reduces the amount of short wavelength radiation that escapes.
