Astronomy 105 - Chapter 8 Exam
Questions Correctly Answered.
The following images show Earth and the four jovian planets of our solar system. Rank these planets
from left to right based on their distance from the Sun, from closest to farthest. (Not to scale.) -
CORRECT ANSWER Earth, Jupiter, Saturn, Uranus, Neptune
The following images show Earth and the four jovian planets of our solar system. Rank these planets
from left to right based on their size (average equatorial radius), from smallest to largest. (Not to scale.)
- CORRECT ANSWER Earth, Neptune, Uranus, Saturn, Jupiter
The following images show Earth and the four Jovian planets of our solar system. Rank these planets
from left to right based on their mass, from lowest to highest. - CORRECT ANSWER Earth, Uranus,
Neptune, Saturn, Jupiter
Which lists the Jovian planets in order of increasing distance from the Sun? - CORRECT ANSWER Jupiter,
Saturn, Uranus, Neptune
Why does Neptune appear blue and Jupiter red? - CORRECT ANSWER Methane in Neptune's
atmosphere absorbs red light.
Why is Jupiter denser than Saturn? - CORRECT ANSWER Its higher mass and gravity compress its interior.
Some jovian planets give off more energy than they receive because of - CORRECT ANSWER ongoing
contraction or differentiation.
Io experiences tidal heating primarily because _______ - CORRECT ANSWER Io's elliptical orbit causes
the tidal force on Io to vary as it orbits Jupiter.
As you learned in Part A, Io's elliptical orbit is necessary to its tidal heating. This elliptical orbit, in turn, is
a result of the orbital resonance among Io, Europa, and Ganymede. This orbital resonance causes Io to
have a more elliptical orbit than it would otherwise, because __________. - CORRECT ANSWER Io
periodically passes Europa and Ganymede in the same orbital position.
