Select the two correct answers.(1 point) Responses its distance from the other galaxy its distance from the other galaxy its age compared to that of the other galaxy its age compared to that of the other galaxy its size compared to that of the other galaxy its size compared to that of the other galaxy its proportion of gas compared to that of the other galaxy
The factors most likely to affect whether a galaxy will evolve by merging with a second galaxy are its distance from the other galaxy and its size compared to that of the other galaxy.
The factors that are most likely to affect whether a galaxy will evolve by merging with a second galaxy are:
1. Its distance from the other galaxy
2. Its proportion of gas compared to that of the other galaxy
The factors that are most likely to affect whether a galaxy will evolve by merging with a second galaxy are its distance from the other galaxy and its size compared to that of the other galaxy.
To determine the correct answers, we need to understand the process of galaxy evolution through merging. When two galaxies come close enough to each other, the gravitational interaction between them can cause them to merge. The outcome of the merger depends on several factors, but distance and size are key considerations.
1. Distance: If two galaxies are far apart, the gravitational forces between them will be weaker, reducing the likelihood of a merger. Therefore, galaxies that are closer to each other have a higher chance of evolving through merging.
2. Size: The relative sizes of the galaxies also play a role. Generally, larger galaxies have stronger gravitational forces, making it more likely for them to merge with smaller galaxies. This is because the larger galaxy's gravity dominates and pulls in the smaller galaxy.
On the other hand, the age of the galaxies and their proportion of gas compared to each other are not directly related to the likelihood of galactic mergers. While these factors may influence other aspects of galaxy evolution, they are not the primary factors determining whether a merger will occur.
So, the correct answers are:
- Its distance from the other galaxy
- Its size compared to that of the other galaxy
