Basic Skills/Definitions Quiz
Part A
Which of the following is NOT a general characteristic of the four jovian planets in our solar system?
Hint A.1
Study Section 11.1
ANSWER:

They are composed mainly of hydrogen, helium, and hydrogen compounds. They are higher in average density than are the terrestrial planets. They lack solid surfaces. They are much more massive then any of the terrestrial planets.
Part B
Which of the following best describes the internal layering of Jupiter, from the center outward?
Hint B.1
Study Section 11.1
ANSWER:

Core of rock and metal; mantle of lower density rock; upper layer of gaseous hydrogen; cloud layer. Core of rock, metal, and hydrogen compounds; thick layer of metallic hydrogen; layer of liquid hydrogen; layer of gaseous hydrogen; cloud layer. Liquid core of hydrogen compounds; liquid hydrogen layer; metallic hydrogen layer; gaseous hydrogen layer; cloud layer. Solid rock core; layer of solid metallic hydrogen; layer of pure liquid hydrogen; cloud layer.
Part C
The energy in the atmospheres of most of the jovian planets comes from
Hint C.1
Study Section 11.1
ANSWER:

the Sun. The Sun and their interiors, in roughly equal proportions. Tidal heating. their interiors.
Part D
Which of the following statements comparing the jovian interiors is NOT thought to be true?
Hint D.1
Study Section 11.1
ANSWER:

They all have the same exact set of internal layers, those these layers differ in size. They all have cores that contain at least some rock and metal. They all have cores of roughly the same mass. Deep inside them, they all have pressures far higher than that found on the bottom of the ocean on Earth.
Part E
Overall, Jupiter's composition is most like that of ______.
Hint E.1
Study Section 11.1
ANSWER:

a comet the Sun an asteroid Earth
Part F
Jupiter's colors come in part from its three layers of clouds. Which of the following is NOT the primary constituent of one of Jupiter's cloud layers?
Hint F.1
Study Section 11.1
ANSWER:

clouds of ammonia clouds of sulfuric acid clouds of water clouds of ammonium hydrosulfide
Part G
How do typical wind speeds in Jupiter's atmosphere compare to typical wind speeds on Earth?
Hint G.1
Study Section 11.3
ANSWER:

They are slightly faster than average winds on Earth. They are much faster than hurricane winds on Earth. They are about the same as average winds on Earth. They are slightly slower than average winds on Earth.
Part H
What is the Great Red Spot?
Hint H.1
Study Section 11.3
ANSWER:

The Great Red Spot is a long-lived, high-pressure storm on Jupiter. The Great Red Spot is a region on Jupiter where the temperature is so high that the gas glows with red visible light. The Great Red Spot is a hurricane that comes and goes on Jupiter. The Great Red Spot is a place where reddish particles from Io impact Jupiter's surface
Part I
What atmospheric constituent is responsible for the blue color of Uranus and Neptune?
Hint I.1
Study Section 11.1
ANSWER:

Methane Hydrogen Ammonia Water
Part J
How does the strength of Jupiter's magnetic field compare to that of Earth's magnetic field?
Hint J.1
Study Section 11.1
ANSWER:

Jupiter's magnetic field is about 20,000 times as strong as Earth's. Jupiter's magnetic field is about twice as strong as Earth's. Jupiter's magnetic field strength is about the same as Earth's. Jupiter's magnetic field is much weaker than Earth's.
Part K
Which of the following statements about the moons of the jovian planets is NOT true?
Hint K.1
Study Section 11.2
ANSWER:

The majority of the moons are large enough to be spherical in shape, while only a few have the more potato-like shapes of asteroids. Many of the moons are made largely of ices. Some moons have an atmosphere. Some of the moons are big enough that we'd probably call them planets if they orbited the Sun.
Part L
The most volcanically active body in our solar system is ______.
Hint L.1
Study Section 11.2
ANSWER:

Europa Io Earth Triton
Part M
The Huygens probe landed on Titan in January 2005, taking pictures and measuring the atmosphere as it descended. What did it find?
Hint M.1
Study Section 11.2
ANSWER:

Lava flows of molten basalt. Primitive life forms. A completely cratered surface. Erosional features such as dry river valleys and lakebeds.
Part N
Which moon is considered likely to have a deep, subsurface ocean of liquid water?
Hint N.1
Study Section 11.2
ANSWER:

Io Europa Miranda Triton
Part O
Among all the large jovian moons, one is thought to have been captured into its present orbit rather than having formed in the "miniature solar nebula" that formed its planet. Which one?
Hint O.1
Study Section 11.2
ANSWER:

Triton Io Callisto Titan
Part P
Which statement about planetary rings is NOT true?
Hint P.1
Study Section 11.3
ANSWER:

Rings are not solid, but rather consist of many small, individual particles. Rings are always located closer to a planet's surface than any large moons. All four jovian planets have rings. Saturn's rings formed along with its moons 4.6 billion years ago.
