question 43

Multiple Choice

Why is a dense cloud more likely to produce an elliptical galaxy than a spiral galaxy?

• A)The more frequent collisions between particles randomize the particle orbits.
• B)The higher density of gas has a stronger force of gravity, and therefore the cloud collapses more quickly.
• C)The higher gas density forms stars more efficiently, so all the gas is converted into stars before a disk can form.
• D)The force of gravity can pull the material into a more spherical shape.
• E)The thickness of the dense cloud prevents a disk from forming.
