What causes sunspots?
A) Magnetic fields inhibit the emission of radiation from atoms in the solar surface.
B) Magnetic fields below the photosphere pull gas down,creating holes in the photosphere.
C) Differential rotation on the Sun creates vortices,or eddies,which are cooler and darker than the rest of the solar surface.
D) Magnetic fields breaking through the photosphere inhibit gas motion where the field is strong,lowering the amount of heat transferred to the surface.

Question

Quizplus · Accepted Answer

Magnetic fields breaking through the photosphere inhibit gas motion in areas where the field is strong, which reduces the amount of heat transferred to the surface, leading to cooler, darker regions known as sunspots.
