Irregularities in brightness on the Sun's photosphere granules. are produced by___________ .
A) different elemental abundances being stirred within the photosphere, to produce variable brightness
B) large convective cells within the photosphere
C) local violent explosions within the photosphere equivalent to a hydrogen bomb explosion

Question

Quizplus · Accepted Answer

The irregularities in brightness on the Sun's photosphere granules are produced by large convective cells within the photosphere. As hot material rises and cooler material sinks, it causes a mottled appearance on the photosphere. This is visible as the granules seen on the Sun's surface.
