Astronomy 1010 Exam #2 Chapter 7
Questions With Correct Answers
Comparing objects in a related group can reveal patterns among them.
| | | | | | | | | | |
These patterns in turn can help us learn more about those objects than
| | | | | | | | | | | | |
we could by studying each individually.
| | | | |
With this goal in mind, watch this animation of the planets in the Solar
| | | | | | | | | | | | | |
System and select all of the following choices that describe the patterns
| | | | | | | | | | | |
that you've observed. As you do so, think about the implications of how
| | | | | | | | | | | | |
the Solar System may have formed.
| | | | |
Choose one or more: | | |
A. The size of all planets increases with distance from the Sun.
| | | | | | | | | | |
B. Planets orbit the Sun in random directions.
| | | | | | |
C. All planets orbit the Sun in a roughly flat plane.
| | | | | | | | | |
D. The closest planets to the Sun are much smaller than the planets that
| | | | | | | | | | | | |
are farther away.
| | |
E. The orbits of the outer planets (those most distant from the Sun) are
| | | | | | | | | | | | | |
spaced farther apart from one another than the orbits of the inner
| | | | | | | | | | | |
planets.
, F. The orbits of the planets are evenly distributed in distance from -
| | | | | | | | | | | | |
CORRECT ANSWER✔✔-C. All planets orbit the Sun in a roughly flat
| | | | | | | | | | |
plane.
D. The closest planets to the Sun are much smaller than the planets that
| | | | | | | | | | | | |
are farther away.

E. The orbits of the outer planets (those most distant from the Sun) are
| | | | | | | | | | | | | |
spaced farther apart from one another than the orbits of the inner
| | | | | | | | | | | |
planets.
G. All planets orbit the Sun in the same direction.
| | | | | | | | |
A new star is forming inside this glowing cloud of gas. The dark band in
| | | | | | | | | | | | | | |
the middle is made of a disk of thick dust, which obscures the light
| | | | | | | | | | | | | |
within it and hides the forming star from view.
| | | | | | | |
Newly forming stars are surrounded by gas and dust. Based on this
| | | | | | | | | | | |
observation--and your previous observations about the relative orbits, | | | | | | | |
positions, and sizes of the planets--what is the most likely scenario for
| | | | | | | | | | | |
the formation of the Solar System?
| | | | |
Choose one: |
A. A cloud of gas and dust collapsed into a flattened disk, within which
| | | | | | | | | | | | | |
the Sun and planets formed.
| | | |
B. Two stars collided and broke apart to form the Sun and the planets.
| | | | | | | | | | | | |
C. A cloud of gas and dust collapsed into a spherical shape, within which
| | | | | | | | | | | | | |
the Sun and planets formed.
| | | |
D. The Sun formed by itself from a collapsing cloud of gas and dust, then
| | | | | | | | | | | | | |
later gravitationally captured the planets as they happened to pass by. -
