Maila states that a certain layer of the sun is like the main engine of a car where all the energy required to make the car work is produced.

Which layer of the sun is Malia referring to?

A) convective zone

B) inner core

C) photosphere

D) radiative zone

Answer is: B) inner core.

The Sun interior is divided into three regions: the inner core, the radiative zone and the convection zone.

The inner core is the central region of the Sun and all solar energy is produced in the core by nuclear fusion.

Radiative zone is a round the inner core and in this area energy is transported by radiation.

The convection zone is the outer-most layer of the interior and in this area energy is transported by convection.
