Quizizz Review ESS1.2 Galaxies

A student observes the night sky. What data will allow the student to confirm if a point of light is a galaxy?

• It contains stars and remains motionless.

• It contains gas, dust, and many stars.

• It orbits a planet.

• It is part of a pattern of stars.

Answer explanation

To confirm a point of light is a galaxy, it should contain gas, dust, and many stars, as these are characteristic features of galaxies. The other options do not provide sufficient evidence to identify a galaxy.

The diagram shows different types of galaxies (T-W). Which galaxy is most similar to the Milky Way, and why?

• Galaxy T; it has a spiral shape.

• Galaxy T; it has an elliptical shape.

• Galaxy U; it has a spiral shape.

• Galaxy U; it has an elliptical shape.

Answer explanation

Galaxy T is most similar to the Milky Way because it has a spiral shape, which is characteristic of spiral galaxies. The Milky Way itself is a spiral galaxy, making Galaxy T the correct choice.

The diagram shows the location of the Sun in the Milky Way galaxy with the spiral arms labeled. Based on the diagram, which statement correctly explains the position of Earth within the Milky Way?

• Earth is located in the Orion arm.

• Earth is located in the Cygnus arm.

• Earth is located between the Carina and Orion arms.

• Earth is located between the Cygnus and Perseus arms.

Answer explanation

Earth is located in the Orion arm of the Milky Way galaxy, which is a well-known spiral arm. This distinguishes it from the other options, which incorrectly place Earth in different arms or between them.

The image shows a galaxy like the Milky Way. What type of galaxy does the image show?

• elliptical

• irregular

• lenticular

• spiral

Answer explanation

The image depicts a galaxy similar to the Milky Way, which is classified as a spiral galaxy. Spiral galaxies are characterized by their distinct arms and a central bulge, making 'spiral' the correct choice.

The data table lists information about five galaxies. Which statement is correct about the Milky Way galaxy?

• The Milky Way galaxy is larger in size than the Triangulum galaxy.

• The Milky Way galaxy has more stars than the Andromeda galaxy.

• The Milky Way galaxy is larger than the IC 1101 galaxy.

• The Milky Way galaxy has fewer stars than the Large Magellanic Cloud galaxy.

Answer explanation

The Milky Way galaxy is indeed larger in size than the Triangulum galaxy, making the first statement correct. The other statements are inaccurate regarding the relative sizes and star counts of the mentioned galaxies.

The diagram shows the shapes of different galaxies. Which statement correctly compares the shapes of the galaxies?

• Both Andromeda and the Milky Way are spiral galaxies.

• Both Centaurus A and the Milky Way are elliptical galaxies.

• The Milky Way, Andromeda, and Centaurus A are lenticular galaxies.

• Centaurus A, Andromeda, and Large Magellanic Cloud are irregular galaxies.

Answer explanation

Both Andromeda and the Milky Way are classified as spiral galaxies, characterized by their distinct spiral arms. The other statements incorrectly categorize the shapes of the galaxies.

Based on the diagram, where is our solar system located in the Milky Way galaxy?

• Our solar system is in the center of the galaxy.

• Our solar system is halfway between two spiral arms moving around the center of the galaxy.

• Our solar system is on the spiral arm farthest from the center of the galaxy.

• Our solar system is about two-thirds of the way outward from the center of the galaxy.

Answer explanation

Our solar system is located about two-thirds of the way outward from the center of the Milky Way galaxy, specifically in the Orion Arm, which is between the center and the outer edges of the galaxy.

Which statement correctly compares the size of the Milky Way with other galaxies?

• The Milky Way is the smallest galaxy in the universe.

• The Milky Way is smaller than Sombrero.

• The Milky Way is the largest galaxy in the universe.

• The Milky Way is larger than Messier 63.

Answer explanation

The Milky Way is larger than Messier 63, which is a smaller spiral galaxy. This makes the statement "The Milky Way is larger than Messier 63" the correct comparison among the options provided.

Which image correctly places a star to show the location of our solar system within the Milky Way galaxy?

• A

• B

• C

• D

Answer explanation

Choice B correctly shows the location of our solar system in the Milky Way galaxy, positioned in the Orion Arm, which is a well-established representation of our solar system's location.

A drawing of a galaxy is shown. What is the shape of the galaxy?

• elliptical

• irregular

• lenticular

• spiral

Answer explanation

The galaxy shown is classified as irregular due to its lack of a defined shape, unlike elliptical, lenticular, or spiral galaxies which have more structured forms. Irregular galaxies often appear chaotic and asymmetrical.
