Answer: Layers of the Sun are : Core, Radiative zone and convection zone
(all three constitutes inner layers), photosphere, chromosphere, transition region and corona (all four constitutes outer layer).
Explanation:
The Sun is made from hydrogen and helium.
The Sun is consists of inner and outer layer. Inner layer constitutes main part of the Sun and is further classified into 3 parts - Core, Radiative zone and convection zone .
The atmosphere of Sun forms it's outer layer which comprises 4 parts - photosphere, chromosphere, transition region and corona.
Light and heat radiated from Sun is energy that is released from Sun as part of nuclear reaction that takes part in it's middle part know as core.
Energy from core moves as electromagnetic radiation towards radiative zone, from where is moves out further by photon carriers.
From radiative zone energy moves towards convection zone. This zone is the outer most of zone of Sun's inner layer and it is here where light energy coming from core layer is converted into light form.
