Which of the following types of protogalactic clouds is most likely to form a spiral galaxy?
A)a very low-density cloud with very little angular momentum
B)a dense cloud with very little angular momentum
C)a low-density cloud with quite a bit of angular momentum
D)a dense cloud with quite a bit of angular momentum
E)a very massive cloud with any density and a lot of angular momentum

Question

Quizplus · Accepted Answer

Spiral galaxies are thought to form from protogalactic clouds that have a significant amount of angular momentum. This angular momentum causes the cloud to flatten as it collapses, leading to the formation of a disk structure characteristic of spiral galaxies. A low-density cloud with quite a bit of angular momentum (option C) is more likely to lead to this outcome compared to the other options provided.
