which processes transfer energy from the core to the photosphere?\nradiation, then friction\nconvection, then conduction\nradiation, then convection\nconduction, then friction
Answer
Brief Explanations:
In the Sun, energy is first transferred from the core to outer - layers by radiation. Then, in the outer layers, energy is transferred by convection to the photosphere. Conduction and friction are not the main energy - transfer processes in this context.
Answer:
radiation, then convection
