Quiz # 4
Question 1
4 Points
Most of the Moon's surface is densely covered with craters, but we find relatively few craters within the lunar maria. What can we conclude?
A
Erosion affects the
maria
more than it affects other regions of the Moon.
B
The
maria
formed after the heavy bombardment ended.
C
The regions of the
maria
were hit by fewer impacts than the densely cratered regions.
D
The
maria
formed within the past 1 billion years.
Question 2
4 Points
Which of the following worlds has the most substantial atmosphere?
A
Mercury
B
Mars
C
Earth
D
Venus
E
the Moon
Question 3
4 Points
The current atmospheric concentration of carbon dioxide on Earth is at its highest in over a million years.
A
True
B
False
Question 4
4 Points
We are confident that rising CO
2
levels are caused by the burning of fossil fuels because atmospheric CO
2
now has the same carbon isotope ratio as fossil fuels.
A
True
B
False
Question 5
4 Points
Earth is habitable because of the greenhouse effect.
A
True
B
False

4 Points
According to our theory of solar system formation, what are asteroids and comets?

chunks of rock or ice that condensed after the planets and moons finished forming
B
leftover planetesimals that never accreted into planets
C
the shattered remains of collisions between planets
D
chunks of rock or ice that were expelled from planets by volcanoes

4 Points
Jupiter and the other gas giants formed close to the sun and migrated outward.
A
True
B
False
Question 8
4 Points
According to our theory of solar system formation, which law best explains why the central regions of the solar nebula got hotter as the nebula shrank in size?
A
Newton's third law
B
the law of conservation of angular momentum
C
the two laws of thermal radiation
D
the law of conservation of energy
Question 9
4 Points
At greater distances from the sun, planetary surface temperatures increase.
A
True
B
False

Question 11
4 Points
Earth is the only terrestrial planet to have experienced tectonic stresses and volcanic activity.
A
True
B
False
Question 12
4 Points
Which of the following best describes convection?
A
It is the process in which a liquid separates according to density,
such as oil and water separating in a jar.
B
It is the process by which rocks sink in water.
C
It is the process in which bubbles of gas move upward through a liquid.
D
It is the process in which warm material gets even warmer and cool material gets even cooler.
E
It is the process in which warm material expands and rises while cool material contracts and falls.
Question 13
4 Points
The lithosphere of a planet is the layer that consists of
A
the rigid rocky material of the crust and uppermost portion of the mantle.
B
the lava that comes out of volcanoes.
C
material between the crust and the mantle.
D
the softer rocky material of the mantle.
E
material above the crust.
Question 14
4 Points

acid rain
B
plate tectonics
C
wind erosion

impact cratering
Question 15
4 Points
Which of the following is the most basic definition of a greenhouse gas?
A
a gas that makes a planet much hotter than it would be otherwise, even in small amounts
B
a gas that absorbs infrared light
C
a gas that reflects a lot of sunlight
D
a gas that keeps warms air from rising, and therefore warms the surface
Question 16
4 Points
Why is Mars so much colder than the Earth?
A
because the albedo of Mars is higher than the Earth
B
because Mars has a much thinner, more diffuse atmosphere
C
because Mars is farther from the Sun

Question 18
4 Points
Why is Venus so much hotter than the Earth?
A
because it rotates backwards compared to its orbital rotation
B
because it is closer to the Sun
C
because it has much more carbon dioxide in its atmosphere
