C) the planet has a magnetic field.
D) there is intelligent life on the planet producing the aurora from below.

Accepted Answer

Auroras are caused by the interaction of charged particles from the solar wind with a planet's magnetic field and atmosphere, indicating the presence of a magnetic field.

Question 8

Which of the following is a common characteristic of the Jovian planets?
A) mostly composed of hydrogen and helium
B) thick atmosphere
C) lack of solid surface
D) ring systems and satellites
E) All of these choices are correct.

Accepted Answer

Jovian planets, also known as gas giants, share characteristics such as being mostly composed of hydrogen and helium, having thick atmospheres, lacking solid surfaces, and possessing ring systems and numerous satellites.

Question 9

Why do astronomers believe that the Jovian planets are composed mainly of hydrogen and helium?
A) Because hydrogen and helium are the main constituents of the Solar System.
B) Because the Jovian planets are very large.
C) Because the Jovian planets have low densities.
D) The Voyager missions measured the chemical compositions of the interiors of the Jovian planets.

Accepted Answer

The Jovian planets have low densities, which suggests that they are composed mainly of light elements such as hydrogen and helium.

Question 10

Why do astronomers believe that the Jovian planets must contain rocky material in their cores?
A) Because silicates and irons were part of the overall composition of the Solar nebula.
B) Because the Jovian planets have large magnetic fields.
C) Because the Jovian planets have large gravity.
D) The statement of the question is incorrect. Astronomers believe that the Jovian planets consist exclusively of hydrogen and helium.

Accepted Answer

The Jovian planets are believed to have rocky cores because silicates and irons were part of the overall composition of the Solar nebula, which contributed to the formation of these planets.

Question 11

Of all the Jovian planets ______ shows signs of tectonic plate motion.
A) Jupiter
B) Saturn
C) Uranus
D) Neptune
E) None of these choices is correct.

Accepted Answer

None of the Jovian planets, which include Jupiter, Saturn, Uranus, and Neptune, show signs of tectonic plate motion. Tectonic activity is primarily associated with rocky planets like Earth.

Question 12

The colors of Jupiter's clouds suggest the presence of ______.
A) organic molecules
B) hydrogen and helium
C) carbon dioxide
D) red-shifted colors due to the fast motion
E) iron oxides

Accepted Answer

The colors of Jupiter's clouds are primarily due to the presence of organic molecules and compounds like ammonia, methane, and other hydrocarbons, which interact with sunlight to produce various colors.

Question 13

The energy that stirs the circulation in Jupiter's atmosphere comes from __________.
A) the Sun
B) the planet's interior
C) the tidal force of the Galilean moons
D) the planet's magnetic field

Accepted Answer

Jupiter's atmosphere is primarily driven by the heat escaping from its interior, which is more significant than the solar energy it receives.

Question 14

The powerful _____ Jupiter is a result of the ______ and ______ in the interior of the planet.
A) magnetic field of; Coriolis effect; heat generated
B) wind on; rotation; excess hydrogen
C) magnetic field; rapid rotation; heat generated
D) wind on; Coriolis effect; heat generated

Accepted Answer

Ganymede is the largest of the Galilean moons and is also the largest moon in the solar system.

Question 16

The average density of the Galilean satellites of Jupiter _____ with increasing distance from the planet.
A) increases
B) decreases
C) does not change

Accepted Answer

The average density of the Galilean satellites decreases with increasing distance from Jupiter, as the inner moons are rocky and dense, while the outer ones are composed of more ice and less dense materials.

Question 17

The rings of Jupiter consist primarily of ______.
