Question 1

Both Jupiter and Saturn

a) have liquid metallic hydrogen in their interiors

b) have rings

c) emit more energy than they

absorb from the Sun

d) rotate very rapidly

Question 2

Jovian planets share all of the following traits EXCEPT

a) a low-density gaseous core

b) large magnetic fields

c) a lot of hydrogen and helium gas

d) many moons

e) differential rotation

Question 2

Jovian planets share all of the following traits EXCEPT

b) large magnetic fields

c) a lot of hydrogen and helium gas

d) many moons

e) differential rotation

Explanation: All of the jovian planets

have dense, compact cores more

massive than Earth, which are

surrounded by liquid and gaseous

layers.

Question 3

Jupiter and the other jovian planets are noticeably oblate

because they have

a) very strong magnetic fields

b) powerful gravity pulling on the

poles

c) rapid rotation and a fluid interior

d) many moons that tidally distort

their shapes

e) all of the above

Question 3

Jupiter and the other jovian planets are noticeably oblate

because they have

a) very strong magnetic fields

b) powerful gravity pulling on the

poles

d) many moons that tidally distort

their shapes

e) all of the above

Explanation: All of the jovian planets are

larger than Earth, all spin faster, all have

lower density, and all show a flattened, oblate shape.

Question 4

What is the probable source of the variations in Jupiter’s belts and zones?

a) Convection of ammonia ice upward

b) Differential rotation and underlying

zonal flow

c) Oblateness due to low density

d) Thermonuclear fusion

e) Jupiter’s huge magnetosphere

Question 5

What is the source of Jupiter’s strong magnetic field?

a) Charged particles moving in the atmosphere

b) Thermonuclear fusion in Jupiter’s core

c) The gravitational attraction of

Jupiter’s many large moons

d) The Great Red Spot

e) Metallic hydrogen swirling

in its interior

Question 5

What is the source of Jupiter’s strong magnetic field?

a) Charged particles moving in the atmosphere

b) Thermonuclear fusion in Jupiter’s core

c) The gravitational attraction of

Jupiter’s many large moons

d) The Great Red Spot

in its interior

Question 6

Saturn radiates even more excess energy than Jupiter because

a) Saturn is still radiating heat left over from its formation

b) Saturn’s thick cloud layer contributes to a larger

greenhouse effect

c) helium rain gives off heat as it falls toward Saturn’s center

d) Saturn’s atmosphere contains

methane

e) Saturn can fuse hydrogen into

helium in its core, like the Sun

d) Saturn’s atmosphere contains

methane

e) Saturn can fuse hydrogen into

helium in its core, like the Sun

Explanation: Jupiter and Neptune also radiate

excess heat, most likely left over from their formation.

Question 7

The two outer jovian planets appear bluish in color because

a) gaseous ammonia in their

atmospheres absorbs blue light

b) methane absorbs red light

c) cold hydrogen reflects blue light

d) dust in their atmospheres scatters

blue light, as it does on Earth

Question 8

Which of these is true about the seasons on Uranus?

a) Its strange tilt produces extreme seasonal variations

b) With its tilt of 29º, Uranus has four seasons similar to those on Earth

c) It never shows any weather in its bland clouds

d) It spins so fast all seasons are the same

Question 9

The magnetic fields of which two planets are most

unusual?

a) Jupiter and Neptune

b) Jupiter and Saturn

c) Jupiter and Earth
