Question 1

Uranus and Neptune have methane clouds but Jupiter and Saturn do not.Which factor explains why?

Accepted Answer

A) Temperatures on Jupiter and Saturn are too high for methane to condense. 
B) Jupiter and Saturn do not contain any methane gas. 
C) The rapid rotation of Jupiter and Saturn prevents methane clouds from forming. 
D) The stronger gravity on Jupiter and Saturn pulls methane downward so that it can't form clouds. 
A) Temperatures on Jupiter and Saturn are too high for methane to condense. 
B) Jupiter and Saturn do not contain any methane gas. 
C) The rapid rotation of Jupiter and Saturn prevents methane clouds from forming. 
D) The stronger gravity on Jupiter and Saturn pulls methane downward so that it can't form clouds.

Accepted Answer

A) It may have an ocean of liquid ethane. 
B) Its atmosphere is mostly nitrogen. 
C) Its temperature is too cold for liquid water to exist. 
D) Its surface is hidden from view by its thick atmosphere.

Question 3

Why is there no large temperature variation from the poles to the equator on Jupiter?

Accepted Answer

The surface temperature on Jup

Question 4

Does it make sense that there are such noticeable differences in the jovian planets? Why or why not?

Accepted Answer

All four formed in the outer solar syste

Question 5

Why do the jovian planet interiors differ?

Accepted Answer

A) The more distant planets formed in a cooler region of the solar nebula and therefore contain a greater proportion of ices than the closer jovian planets. 
B) They differ due to giant impacts at the late stages of planet formation. 
C) Accretion took longer further from the Sun,so the more distant planets formed their cores later and captured less gas from the solar nebula than the closer jovian planets. 
D) The solar heating is less for the more distant planets than the closer planets. 
E) The more distant planets had longer to form than the closer planets,since the solar nebula lasted longer at greater distances from the Sun.

Question 6

Process of Science: Why do we think the source of Jupiter's large internal energy come from gravitational contraction?

Accepted Answer

That Jupiter produces more energy than i

Question 7

Some of the moons of the jovian planets have significant atmospheres.

Accepted Answer

A) True 
 B)False

Question 8

Why do astronomers think Miranda has such an unusual surface?

Accepted Answer

A) It underwent an episode of tidal heating in the past. 
B) It was squashed by a giant impact. 
C) It formed from the remains of a giant impact relatively recently. 
D) Its surface is covered with a powdery dust from micrometeorite impacts. 
E) Its low temperature affects the colors of its surface ice.
