A) radiation and convection
B) radiation alone, by photons of energy
C) conduction and convection
D) conduction, convection, and radiation

Quizplus · Accepted Answer

Radiation and convection are the primary means of heat transfer from the solar interior to its surface. Radiation occurs in the sun's core and radiative zone, where energy is transferred outward by photons. Convection occurs in the outer layer, where hot plasma rises, cools, and then sinks back down, transferring heat to the surface. Conduction is not a significant mode of heat transfer in the sun due to the low density of the plasma in its outer layers.
