- The direction a comet tail points is
(a) away from the Sun
(b) away from the Earth
(c) propelling the comet in its direction like an airplane contrail
(d) into the direction the comet is moving like headlights
- Titan has a nitrogen atmosphere much like the Earth, but it's because
(a) H2O is in its oceans which dissolves CO2
(b) nitrogen is the most common volatile molecule in the solar system
(c) H2O and CO2 freeze out
(d) nitrogen is emitted by plants and algaes
- The belts and zones that stripe Jupiter are related to what on Earth?
(a) the reason tides go up and down on beaches
(b) the reason sedimentary rocks have layers

- Carbon dioxide (CO2) is sometimes frozen on Mars but never Venus
because of these two reasons:
(a) distance to the Sun and how much greenhouse effect there is
(b) distance to the Sun and whether CO2 is dissolved in oceans
(c) whether CO2 is dissolved in the ocean and how much greenhouse effect
(d) none of those things matter to whether CO2 is frozen
- The phase (solid, liquid, gas) of the water (H2O) molecule is relevant to the atmosphere
of the Earth because it helps explain why
(a) water is the dominant component of the atmosphere
(b) illumination from the Moon has so many effects on Earth
(c) water is rarely found as liquid on Earth
(d) there is so little carbon dioxide in Earth's atmosphere
- According to the ideal gas law, if you double both the temperature and the density of a gas, the pressure will
(a) be only half as large
(b) stay the same
(c) double
(d) go up by a factor of 4
- Where does the bulk of the gases in the atmosphere of a planet like Mars come from?
(a) they are in the atmosphere from the start
(b) they are outgassed from the planet's interior and comets
(c) they are contributed by living organisms
(d) they are pulled gradually into the planet from the gas in space
- Where does the bulk of the gases in the interior of a planet like Jupiter come from?
(a) they form with the planet from the gaseous disk around the Sun
(b) they are outgassed from the planet's rocky center
(c) they are contributed by living organisms
(d) they are captured gradually over the whole age of the solar system
- The reason the sky is blue is related to why
(a) sunsets are red
(b) prisms bend light of different colors a different angle
(c) a blue shirt absorbs light that isn't blue
(d) something moving toward you at very high speed looks blueshifted
- The speed an air molecule needs in order to escape from a particular planet is
(a) the same for all gases at all heights
(b) a function of the mass of the molecule
(c) dependent only on how high up the molecule is already
(d) dependent on both the molecule's mass and height in the atmosphere
- Which of the following is not intimately related to the other three in Jupiter?
(a) the visible stripes
(b) the planet's rotation
(c) the winds in the atmosphere
(d) the presence of four large moons
- What will happen to the Sun when its core runs out of hydrogen to fuse?
(a) it will rapidly darken and shrink
(b) it will rapidly brighten and expand
(c) its core will collapse and the star will explode
(d) its core will immediately begin fusing helium
- Your ears "pop" when you drive up a mountain because
(a) the temperature gets colder
(b) the weight of the air above you is reduced
(c) the gravity gets weaker
(d) the height makes you feel anxious
- At the end of its life the central core of the Sun will
(a) collapse making the star explode
(b) itself explode like a bomb
(c) cool down and become a white dwarf
(d) continue to balance its losses with fusion
- The tops of mountains are
(a) cold because they are above most of the greenhouse gases
(b) cold because the pressure is low
(c) warm because they are closer to the Sun
(d) warm because the sunlight is more direct
- Why do metals and the molecules in rocks form planets closer to the Sun?
(a) they stick together even if the conditions are hot
(b) they are pulled in by the gravity of icy bodies
(c) they dominate the composition of the solar system
(d) they require high temperature to be able to fuse together
- Why do certain meteor showers happen on the same day every year?
(a) they don't really, it's just a story that gets repeated
(b) the Earth's magnetic field lets them in on those days
(c) because each comes from the dust from a given comet orbit
