Multiple Choice
How does spectroscopy help determine the composition of a planet's atmosphere?
A) Radiation emitted by the planet passes through the atmosphere on its way to Earth, and analysis of the resulting absorption spectrum gives clues to the atmosphere's composition.
B) Heat from the planet makes its atmosphere emit large amounts of radiation. Analysis of the resulting emission spectrum gives clues to the atmosphere's composition.
C) Light from the Sun passes through the planet's atmosphere before and after reflecting from the planet's surface. Analysis of the resulting absorption spectrum gives clues to the atmosphere's composition.
D) At present, the only way to determine the composition of a planet's atmosphere is to have a flyby spacecraft scoop up a sample and then analyze it with an on-board spectrometer.
