|
F
|
|
Jupiter is approximately 30 times more massive than the Earth
|
F
|
|
As seen from the outer giant planets, the Sun would appear as simply a very bright star in a sea of fainter stars
|
T
|
|
Jupiter’s mass is more than twice the mass of all the other planets combined.
|
T
|
|
On the giant planets, the atmospheric vortices that occur almost always lie between oppositely directed zonal winds.
|
T
|
|
Uranus and Neptune are less massive than Jupiter and Saturn, probably because they formed earlier than Jupiter or Saturn.
|
F
|
|
The strong magnetic fields of Uranus and Neptune arise from magnetic dynamos in their liquid rocky cores.
|
F
|
|
When charged particles oscillate around magnetic field lines of a planet they emit radiation in the microwave region of the spectrum.
|
F
|
|
It is theoretically possible for Earth to someday have a temporary ring structure.
|
T
|
|
The presence of shepherd moons keeps the giant planets’ ring systems completely stable and the rings will last forever.
|
F
|
|
The gas giants are composed primarily of:
|
a. hydrogen

|
You could fit roughly __________ Jupiters across the diameter of the Sun and roughly __________ Earths across Jupiter’s diameter.
|
c. 10; 10
|
|
A planet will have bands in its atmosphere like Jupiter and Saturn if:
|
c. the wind speeds vary greatly with latitude
|
|
Uranus and Neptune are bluish green because they contain large amounts of:
|
b. methane
|
|
Why are all clouds on Jupiter not white, as on Earth?
|
c. There are impurities in their ice crystals.
|
|
The fact that Jupiter’s radius is contracting at a rate of 1 mm/year results in:
|
d. Jupiter radiating more heat than it receives from the Sun
|
|
The strongest magnetic fields in the Solar System are found on which planet?
|
a. Jupiter
|
|
Two years after first being observed, astronomers reported that Saturn’s rings vanished. What happened to them?
|
b. The rings lined up with Earth, and they were too thin to be observed.
|
|
Why would a planet’s rings reflect 50 percent of the sunlight they receive?
|
a. They are made of ice.
|
|
Pluto is the largest member of the Kuiper Belt.
|
F
|
|
Eris is classified as an asteroid even though its mass is 28 percent larger than Pluto’s mass.
|
F
|
|
Io is by far the most geologically active moon in the Solar System.
|
T
|
|
Eruptions of water-powered geysers have been seen on the surface of Saturn’s moon Titan.
|
F
|
|
Lakes of methane, ethane, and other hydrocarbons can be found on the surface of Saturn’s moon Titan.
|
T
|
|
The oceans under Europa’s icy crust could be very deep and could contain more water than all the oceans on the Earth.
|
T
|
|
The yellow colored patches of Io’s surface are fields of sulfur dioxide snow.
|
T
|
|
Most asteroids are found in orbit around the Sun between the orbits of Jupiter and Saturn.
|
F
|
|
Some asteroids have moons just as planets do.
|
T
|
|
Although asteroids are small individually, when combined they make up a significant fraction of the total mass of the planets.
|
F
|
|
All short period comets have a period < 20 years.
|
F
|
|
Cometary nuclei provide evidence that the ingredients necessary for the creation of life were present in the early solar nebula.
|
T
|
|
The most common type of meteorites found are iron meteorites
|
F
|
|
Meteorites are more likely to come from asteroids than comets.
|
T
|
|
All meteorites are remnants of planetesimals that never coalesced to form a planet.
|
F
|
|
The surface of the dwarf planet Eris has very high albedo and is covered with:
