Why are the belts and zones on Saturn less distinct than those on Jupiter?
a. Saturn is smaller and less massive than Jupiter, so belts and zones formed deeper in Saturn's atmosphere where the force due to gravity was large enough to contain them.
b. The belts and zones are veiled by a layer of methane crystals in Saturn's upper atmosphere.
c. Saturn is less dense than Jupiter, so belts and zones formed deeper in Saturn's atmosphere where the density was high enough to support them.
d. Saturn has fewer moons than Jupiter, so belts and zones formed deeper in Saturn's atmosphere due to weaker tidal forces pulling outward.
e. Saturn is colder than Jupiter, so belts and zones formed deeper in Saturn's atmosphere where it was hot enough to form.
