Which processes transfer energy from the core to the photosphere?



A. Radiation, then friction

B. Convection, then conduction

C. Radiation, then convection

D. Conduction, then friction

Answer :

Final answer:

Energy from the Sun's core reaches the photosphere primarily through radiation followed by convection. In the core, photons are generated through nuclear fusion and gradually move outward. Once the energy reaches the convective zone, convection then carries it to the surface.


Explanation:

Energy Transfer from the Core to the Photosphere

The transfer of energy from the core of the Sun to the photosphere involves key processes including radiation and convection. The core generates energy through nuclear fusion, which produces photons that travel outwards. However, this energy does not travel directly to the photosphere; instead, it undergoes a series of interactions.

  1. Radiation: Initially, energy is transferred through radiation as photons are absorbed and re-emitted by particles in the dense solar interior. This process can take thousands to millions of years, depending on the conditions.
  2. Convection: Once the energy reaches the outer convective zone of the Sun, it is primarily transported by convection. Hot plasma rises towards the surface, cools down, and then sinks back down, creating convection cells that efficiently transport energy to the photosphere.

In conclusion, the correct answer to the question is that energy is transferred from the core to the photosphere via radiation, then convection.
