Astronomy 210 Quiz 7, fall semester 2012
Cuesta College, San Luis Obispo, CA
Belts and zones on Saturn are less visible than on Jupiter because they:
(A) are periodically impacted by Saturn's ring particles.
(B) have light reflected from Saturn's rings.
(C) have a metal-poor composition.
(D) lie deeper down in Saturn's atmosphere.
Correct answer: (D)
The topmost cloud layers of Jupiter and Saturn's belts and zones are warmed by sunlight; these layers are warmer for Jupiter and cooler for Saturn, such that Saturn's clouds are less buoyant and lie lower, obscured by haze.
