Description

Example Questions Chapter 11 Differential rotation is when a planet's equator and polar regions rotate at different rates True

False

Jupiter has twice the mass of all the other planets combined. True

False

The equator of Jupiter rotates slower than the Great Red spot. True

False

Jupiter's atmosphere is a single huge storm system. True

False

Colors in Jupiter's clouds are largely due to helium compounds. True

False

The clouds of Jupiter are primarily composed of liquid hydrogen.

True

False

The Great Red Spot has been seen on Jupiter as long as we have had scopes capable of observing it. True

False

Jupiter puts back into space twice the energy it gets from the Sun True

False

If it were about 80 times as massive as present, Jupiter could become a star. True

False

Jupiter's magnetic field is much stronger than Earth's, and has a magnetic tail that extends beyond the orbit of Saturn. True

False

Jupiter's magnetosphere generates the strongest radio source in the solar system. True

False

Like Earth, Jupiter's internal energy is generated chiefly by radioactive decay. True

False

Alternating zones of rising and sinking gas in Jupiter's atmosphere create light and dark bands.

cause Jupiter's magnetic field to ripple.

produced the ring system discovered by Voyager.

generate their own magnetic fields.

circle the planet from pole to pole.

How does the heat Jupiter radiates compare to the energy it receives from the Sun? They are equal, as you would expect for a highly reflective planet.

Jupiter's dark belts absorb most of the solar radiation, so it is cooler in the infrared.

Jupiter radiates back into space about twice the energy it gets from the Sun.

Jupiter is a brown dwarf, about a hundred times less luminous than the Sun.

Jupiter is a red dwarf, about a tenth the Sun's luminosity.

What is the source of Jupiter's excess energy? helium vapor raising from its interior

the decay of radioactive elements in its dense core

nuclear fusion in its hot, sunlike core of hydrogen

the slow escape of gravitational energy released during the planet's formation

tidal stresses of the large Galilean moons

What would Jupiter have needed to have become a star? more moons

more mass

a slower rotation, like the Sun

a different chemical composition

a higher density

What is true of Jupiter's magnetosphere? Although its surface field is greater, since the planet is larger the total field is actually weaker than Earth's.

It does not trap protons and electrons, as Earth's Van Allen belts do.

It has a tail that extends at least to Saturn's orbit.

It is only slightly stronger than Saturn's.

It is only slightly stronger than Mars has

No answer text provided.

Compared to its rotational axis, Jupiter's magnetic field: is exactly in alignment.

lies about 10 degrees off, much like our own rotation and magnetic field.

is tilted about 23.5 degrees, much like our own axial tilt.

is tilted 98 degrees, much like the case of Uranus

has yet to be detected

How large is Jupiter's magnetosphere? It is about as large as the Earth's.

It is so large it extends out to the orbit of Io.

It is a million times the volume of the Earth's, extending beyond the orbit of Saturn.

It extends inward to the orbit of Mars.

It envelopes even the Sun and rest of the solar system.

What do our magnetic field and Jupiter's share? similar field strength

same polarity

auroral displays in the polar regions

fields that extend inward all the way to the Sun

fields that extend outward past Pluto

How does the magnetic tilt of Jupiter compare with our field? Both are exactly perpendicular to our equator, aligned with our rotation axis.

Jupiter's lies perpendicular to the ecliptic, while ours is tilted 23.5 degrees.

Both are tilted about 10 degrees, but Jupiter is opposite in polarity.

Both are tilted about 27 degrees, much like Saturn's.

Like Uranus, Jupiter is flopped over on its side.

Which of the Galilean moons is the densest and most geologically active? Io

Europa

Ganymede

Callisto

Titan

The surface of which jovian moon most resembles the pack ice of the Arctic Ocean? Amalthea

Io

Europa

Ganymede

Callisto

In size, from largest to smallest, the correct order for the Galilean moons is: Callisto, Ganymede, Europa, Io.

Ganymede, Callisto, Io, Europa

Io, Europa, Callisto, Ganymede.

Europa, Ganymede, Io, Callisto.

Ganymede, Callisto, Europa, Io

Which statement about Jupiter's moons is FALSE? The four largest were found by Galileo

Almost all appear to keep the same face always pointed at Jupiter as they orbit it.

All have counterclockwise revolution around the giant planet.

Io has larger density than Callisto

Some of the smaller ones are, like Deimos and Phobos of Mars, probably captured asteroids

Where is Jupiter's ring located? above Jupiter's cloud tops and inside the orbit of its inner-most moon

between the orbits of Io and Europa

sharing the orbit of Amalthea

in a thin ring at the distance of Io but inclined by an angle of about 30 degrees to Io's orbit

between Europa and Callisto...
