Question

Which processes transfer energy from the core to the photosphere?

Answer 1

-radiation and convection

Hope this helps :)

Answer 2

Answer:

conduction and convection

Explanation:

Sun is a huge ball of gases- Hydrogen and Helium. Nuclear fusion reaction in the core powers the sun. The heat from the core is transferred to photo-sphere via two modes- convection and conduction.

Conduction is the mode of heat transfer when the particles vibrate at a their fixed position. The particles collide with the neighboring particles and transfer heat. More the temperature, with particles vibrate with greater energy. There is direct contact between particles. conduction happens in solids, liquids and gases.

Convection is the mode of heat transfer in fluids. The fluid heats up near the source and expands. Due to its less density, it rises up and the cool fluid from top rushes to take its place. This process continues.

Convection currents can be observed on the surface of the sun. Due to convection currents, sun has granular texture.
