Use the scenario to answer the question.
A student makes a chart about galaxies and mentions that the universe consists of many galaxies such as the Andromeda galaxy and the Milky Way galaxy.
Which statement is true about these two galaxies?
The Milky Way is a spiral galaxy, and the Andromeda galaxy is not.
The Milky Way is a spiral galaxy, and the Andromeda galaxy is not.
They are both moving away from each other.
The Milky Way galaxy is larger than the Andromeda galaxy.
They both exert a strong gravitational pull on each other
To answer this question, we can start by understanding the scenario. The student made a chart about galaxies and mentioned two specific galaxies, the Andromeda galaxy and the Milky Way galaxy.
Now, let's go through the options given:
Option 1: The Milky Way is a spiral galaxy, and the Andromeda galaxy is not.
To determine if this statement is true, we can do some research. We can look up information about the Milky Way and Andromeda galaxies to find out their classifications. By searching for "Milky Way galaxy" and "Andromeda galaxy," we can find reliable sources such as astronomy websites, books, or scientific journals that provide information about their classifications. From these sources, we can discover that both the Milky Way and Andromeda galaxies are indeed spiral galaxies. Therefore, this statement is not true.
Option 2: They are both moving away from each other.
This option suggests that the Andromeda and Milky Way galaxies are moving away from each other. To determine if this statement is true, we can again search for scientific sources that provide information on the movement of these galaxies. By searching for "Andromeda galaxy movement" and "Milky Way galaxy movement," we can find reliable sources that explain the velocities and directions of motion of these galaxies. From these sources, we can find out that the Andromeda and Milky Way galaxies are indeed on a collision course and moving towards each other, rather than away. Therefore, this statement is not true.
Option 3: The Milky Way galaxy is larger than the Andromeda galaxy.
To find out if this statement is true, we can perform a search for information on the size of the Milky Way and Andromeda galaxies. By searching for "size of Milky Way galaxy" and "size of Andromeda galaxy," we can find reliable sources that provide details about the dimensions and mass of these galaxies. From these sources, we can determine that the Andromeda galaxy is slightly larger than the Milky Way galaxy. Therefore, this statement is not true.
Option 4: They both exert a strong gravitational pull on each other.
To check if this statement is true, we can search for information on the gravitational interactions between the Andromeda and Milky Way galaxies. By searching for "gravitational interaction between Andromeda and Milky Way galaxies," we can find scientific sources that discuss the gravitational forces at play. From these sources, we can confirm that the Andromeda and Milky Way galaxies do exert a strong gravitational pull on each other due to their proximity. Therefore, this statement is true.
In conclusion, based on the research, the statement that is true about the Andromeda and Milky Way galaxies is that they both exert a strong gravitational pull on each other.
