held together by friction.
B. They are have large masses, and can hold billions
of stars.
C. Galaxies can collide together, helping to create
new stars in the process.
D. Our galaxy, The Milky Way Galaxy, is one of
billions of other galaxies located in the universe
3
Which data table best classifies the galaxies
shown in the diagrams?
4
One component of the universe consists of a
large amount of gas and dust that can reflect
light, absorb light, or emit light. When gravity
pulls some of the gas and dust together, they
form a protostar. What is this component of
the universe called
A.
B.
C.
D.
A supernova
A neutron star
A nebula
A black hole
5
What elements have been determine to form in
all stars?
A. helium and carbon
B. hydrogen and iron
C. calcium and other metals
D. hydrogen and helium
6
Which of the following best describes the
relative size of the Sun compared to other
types of stars in the universe?
A. The smallest star in our galaxy
B. The largest star in our galaxy
C. Among the group of largest stars
D. Medium-sized compared to all star
7
The Sun is a star in the Milky Way galaxy. Which
location above best represents the location of
the Sun?
A. Location W
B. Location X
C. Location Y
D. Location Z
8
Which letter correctly represents the location of
the Sun on the HR Diagram
A. a
B. b
C. c
D. d
9
Which table correctly describes the following
stars according to the HR diagram?
10
What is the general relationship between the
surface temperature and brightness of a Main
Sequence star?
A. As the temperature increases, the brightness
decreases.
B. As the temperature increases, the brightness
increases.
C. As the temperature increases, the brightness
remains the same.
D. As the temperature remains the same, the
brightness increases.
11
The Small Magellanic Cloud is an irregular galaxy
that is smaller than our Milky Way galaxy. The
size of the Small Magellanic Cloud is 7500
light-years across. Based on the scale of 1cm =
1000 light-years, which model correctly
represents the size of the Small Magellanic
Cloud?
12
Tau Ceti is a star in the constellation Cetus. The
distance between Tau Ceti and our sun is 11.9
light-years. About how long does it take for
light from Tau Ceti to reach Earth?
A.
B.
C.
D.
11.9 years
11.9 x 9.5 trillion years
11.9 seconds
11.9 x 9.5 trillion seconds
13
Which of the following best explains the part of the wave
represented by λ (lambda)?
A. λ represents how tall the wave is, therefore they all have
the same energy
B. λ represents the distance between two wave peaks,
therefore wave 3 has the most energy
C. λ represents the distance between the top of a wave and
the middle of a wave, therefore they all have the same
energy
D. λ represents the distance between two wave peaks,
therefore wave 2 has the most energy
14
In the electromagnetic spectrum, there are many
different types of waves, including radio waves. Each
of the waves are composed of a different frequency
based on wavelength. Which of the following explains
a way in which the lowest frequency light wave can be
used by scientists to learn about objects in space?
A. Scientists can determine the temperature of distant
objects in space.
B. Scientists can determine the distance objects in space
are from the Earth.
C. Scientists can determine the elements that stars are
composed of.
D. Scientists can determine the relative movement of
objects in space.
15
Looking at the star spectrum above, which conclusion about the
composition of the star is the most accurate?
A. The star is composed of Li, H, He, and Na which means that the star
is older than our star, the sun.
B. The star is only composed of Hydrogen so it would be much
younger than our star, the sun.
C. The star is composed of H, He, and Lithium meaning it is a fairly
young star that is starting to fuse heavier elements
D. The star is composed only of H and He meaning it is relatively
young and most likely part of the Main sequence like our sun.
16
The sun is the only star in our solar system, but one
of many in our galaxy. The other stars seem
much smaller and dimmer, than the sun. Why is
this?
A. The other stars have a smaller diameter than
the sun.
B. The sun is the largest and brightest star in the
Milky Way galaxy.
C. The sun is many times closer to Earth than any
other star.
D. The sun will one day become a supergiant.
17
Scientists measure the movement of distant galaxies to learn
more about the origin of the universe. You researched
scientific data that showed that light from a distant galaxy
is red-shifted. How would you evaluate the data?
A. It indicates that the expansion of the universe has stopped,
and so it does not support the Big Bang theory.
B. It indicates that the galaxy is moving away from Earth, and
so it supports the Big Bang theory.
C. It indicates that the galaxy is moving toward Earth, and so it
supports the Big Bang theory.
D. It indicates that the universe is contracting, and so it does
not support the Big Bang theory
18
Scientists believe that the further the galaxies are
from Earth, the faster they are moving away from
Earth. What scientific data is used as evidence to
support this theory?
A.
B.
C.
D.
blue shifting of light emitted from the galaxies
red shifting of light emitted from the galaxies
the abundance of light elements in the universe
the uniformity of cosmic microwave background
radiation in the universe
