What Is The Radiative Zone Of The Sun

It is adjacent to the core.

The sun s radiative zone is the section of the solar interior between the innermost core and the outer convective zone. Energy is primarily or partially transported by convection in such a region. Layers of the sun. A convection zone convective zone or convective region of a star is a layer which is unstable to convection.

The zone itself has a temperature of around 7 million degrees fahrenheit. The radiation zone is the site where energy transport occurs. It sits outside of the core and it holds its extremely high temperature. For the outer layers the mileage is from the sun s surface.

The inner layers are the core radiative zone and convection zone. This zone can be characterized as the place where we the photons bounce around facilitating the ability for energy to be transported. The hottest part of the sun is the core at 28 080 000 f on average. This layer serves as a passage for all the energy that is released by the core.

In other words the energy is conveyed by photons. The core is at the center. In the radiative zone energy generated by nuclear fusion in the core moves. In the sun the region between the solar core at 0 2 of the sun s radius and the outer convection zone at 0 71 of the sun s radius is referred to as the radiation zone although the core is also a radiative region.

Stellar convection consists of mass movement of plasma within the star which usually forms a circular convection current with the heated plasma ascending and the cooled plasma descending. In this zone energy travels between the atoms as photons of gamma radiation. The convection zone and the radiation zone are divided by the tachocline another part of the sun. The schwarzschild criterion expresses.

When the energy reaches the top of the radiative zone it begins to move in a different fashion in the convective zone. For the inner layers the mileage is from the sun s core. Its name is derived from the way energy is carried outward through this layer carried by photons as thermal radiation. The radiation zone is the middle part of the interior of the sun.

Moving outward next comes the radiative or radiation zone. This graphic shows a model of the layers of the sun with approximate mileage ranges for each layer. In a radiation zone energy is transported by radiation and conduction. It the hottest region where the nuclear fusion reactions that power the sun occur.
