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.

Mars
C
Earth

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

the law of conservation of angular momentum

the two laws of thermal radiation

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.
