How is heat transfer from the Sun to the Earth carried out? a) thermal conductivity b) convection c) radiation d) all these methods

In order for heat transfer through heat conduction to be possible, direct contact of the molecules of the two substances is necessary, but there is a huge distance between the Sun and the Earth, therefore this option is incorrect.

In order for heat transfer by convection to be possible, a conductor (for example, air) is needed that will transfer heat from the Sun to the Earth, but there is a vacuum in space, therefore this option is incorrect.

When emitted, heat is transferred by microparticles (mainly photons).

Therefore, the correct answer is: c) radiation.
