Trang 2Mercury’s surface most resembles which of these?
a) The Moon’s far side
b) Venus’s polar regions

Trang 5Mercury is very hard to observe from Earth because
a) it always appears only half lit
b) it is never more than 28º from
the Sun.
c) its elliptical orbit causes it to change
speed unpredictably
d) its surface reflects too little sunlight
e) its surface does not allow radar to
bounce back to Earth
Explanation: Mercury’s inner orbit keeps
it close to the Sun, visible only for an hour
Trang 6How do the atmospheres of the Moon and Mercury compare?
dioxide
nitrogen atmosphere
no information exists about Mercury’s

Trang 7How do the atmospheres of the Moon and Mercury compare?
dioxide
nitrogen atmosphere
no information exists about Mercury’s
Explanation: The lack of an atmosphere acting as
a protective layer contributes to their extremely
cratered surfaces
Trang 8Mercury has extreme high and low temperatures between night and day because
a) it is so close to the Sun
b) its surface rocks don’t retain heat
c) it spins too fast to cool down
d) Mercury’s axis has no tilt; its
equator receives direct sunlight
e) it has no atmosphere to moderate
temperatures over the globe

Trang 9Mercury has extreme high and low temperatures between night and day because
a) it is so close to the Sun
b) its surface rocks don’t retain heat
c) it spins too fast to cool down
d) Mercury’s axis has no tilt; its
equator receives direct sunlight
e) it has no atmosphere to moderate
temperatures over the globe.
Explanation: Mercury’s low mass and very high sunlit surface temperature of 700 K explain why it has no atmosphere
Trang 10Which statement about the rotations of Mercury and the Moon is FALSE?
a) Our Moon keeps the same side toward us
b) The rotation period of Mercury is 59
Earth days
c) Like our Moon, Mercury does not rotate
at all, keeping the same side facing the Sun
d) On Mercury, 3 “days” equals 2 “years.”
e) On the Moon, each “day” lasts about
15 Earth days of constant sunlight

Trang 11Which statement about the rotations of Mercury and the Moon is FALSE?
a) Our Moon keeps the same side toward us
b) The rotation period of Mercury is 59
Earth days
c) Like our Moon, Mercury does not rotate
at all, keeping the same side facing the Sun
d) On Mercury, 3 “days” equals 2 “years.”
e) On the Moon, each “day” lasts about
15 Earth days of constant sunlight
Explanation: Both Mercury and the Moon rotate slowly and
show a “spin-lock” created by tidal forces from nearby large objects
Trang 12Which of the following inner solar system bodies has the densest atmosphere?
Trang 13Which of the following inner solar system bodies has the densest atmosphere?
Explanation: Venus’s atmosphere has a
pressure about 90 times greater than
Earth’s Many of its surface features are
affected by this immense pressure
Trang 14The greenhouse effect on Venus is due to _ in its atmosphere.
Trang 15The greenhouse effect on Venus is due to _ in its atmosphere.
Explanation: Venus’s atmosphere
is over 96% CO2, resulting in a
surface temperature exceeding
900ºF
Trang 16Venus’s surface shows all of the following EXCEPT
a) many impact craters of all sizes
Trang 17Venus’s surface shows all of the following EXCEPT
a) many impact craters of all sizes.
Explanation: Venus’s thick
atmosphere shields the planet
from smaller meteor impacts
Trang 18What effect does the greenhouse effect have on the surface environment of Venus?
a) Little or no effect
b) About the same as on Earth
c) To reduce the surface temperature
by about 30ºC
d) To raise the surface temperature
by hundreds of degrees Celsius
e) To cause the surface temperature of
Venus to become hotter than the Sun

Trang 19What effect does the greenhouse effect have on the surface environment of Venus?
a) Little or no effect
b) About the same as on Earth
c) To reduce the surface temperature
by about 30ºC
d) To raise the surface temperature
by hundreds of degrees Celsius
e) To cause the surface temperature of
Venus to become hotter than the Sun
Explanation: Even though Venus is farther from the Sun than Mercury, it actually has a higher surface temperature because of the greenhouse effect
Trang 20Which of the following inner solar system bodies has the largest volcanoes?
Trang 21Which of the following inner solar system bodies has the largest volcanoes?
Explanation: Mars’s largest
volcano, Olympus Mons, rises
more than 25 km (75,000 ft) above
the surrounding plains
Trang 22Venus and Mars probably evolved differently from Earth because they
a) are slightly bigger than Earth
b) are more massive than Earth
c) have thicker atmospheres than Earth
d) formed sooner than Earth
e) orbit at different distances from the Sun
