Sun interior is divided in to 4 regions

1) the core

The Sun's center is the focal area where atomic responses expend hydrogen to shape helium.The temperature at the exceptionally middle of the Sun is around 15,000,000° C (27,000,000° F) and the thickness is around 150 g/cm³ .Both the temperature and the thickness diminish as one moves outward from the focal point of the center of the sun.

2)The radio active zone

The radiative zone augments outward from the external edge of the center to the interface layer or tachocline at the base of the convection zone.The radiative zone is portrayed by the strategy for vitality transport - radiation.The radiative zone is described by the system for vitality transport - radiation.The thickness drops from 20 g/cm³  down to just 0.2 g/cm³ (not exactly the thickness of water) from the base to the highest point of the radiative zone. The temperature tumbles from 7,000,000° C to around 2,000,000° C over the same separat

3) the interface layer

The interface layer lies between the radiative zone and the convective zone. The smooth movements found in the convection zone gradually vanish from the highest point of this layer to its base where the conditions coordinate those of the cool radiative zone.

4) the convection zone

The convection zone is the external most layer of the sun oriented inside. It stretches out from a profundity of around 200,000 km up to the noticeable surface. At the base of the convection zone the temperature is around 2,000,000° C. This is sufficiently cool for the heavier particles, (for example, carbon, nitrogen, oxygen, calcium, and iron) to clutch some of their electrons.In this zone the convective movements convey warm quickly to the surface. The liquid extends and cools as it rises. At the unmistakable surface the temperature has dropped to 5,700 K and the thickness is just 0.0000002 gm/cm.
