Answer: Layer's of the Sun.
Explanation:
The three words of the list correspond to the layers of the interior and atmosphere of the Sun.
This briefly tells you what every layer is:
Core: it is the central zone of the zone.
There is where the nuclear reactions (fusion) that transform hydrogen into helium and produce vast amounts of energy occur.
Radiation zone:
Is a very hot region in the interior of the sum where electromagnetic radiation is the mechanism of heat energy transference.
Convection zone
<span>It is the outermost layer of the interior of the Sun, which is less dense than the radiation zone and the main heat transference mechanism is convection.
