What effect are magnetic fields thought to have on star formation in molecular clouds?
A)They can help resist gravity,so that more total mass is needed before the cloud can collapse to form stars.
B)They accelerate the star formation process.
C)They allow small stars to form in isolation within gas clouds.
D)None-there are no magnetic fields in interstellar space.

Question

Quizplus · Accepted Answer

Magnetic fields can provide support against gravity in a molecular cloud, making it more difficult for the cloud to collapse and form stars. This means that a greater total mass is required in the cloud before star formation can occur.
