Convection zone - Wikipedia
A convection zone, convective zone or convective region of a star is a layer which is unstable due to convection. Energy is primarily or partially transported by convection in such a region. In a radiation zone, energy is transported by radiation and conduction.

2022年9月22日 · The convection zone is the outer-most layer of the solar interior. It extends from a depth of about 200,000 km right up to the visible surface. At the base of the convection zone the temperature is about 2,000,000° C.

2024年2月3日 · The four layers of the Sun are the core, radiative zone, convective zone, and atmosphere. The Sun is a colossal nuclear reactor at the heart of our solar system. Our favorite star is about 109 times the diameter of Earth and over 330,000 times its mass.

2013年1月23日 · The Convection Zone – Energy continues to move toward the surface through convection currents of the heated and cooled gas. The Chromosphere – This relatively thin layer of the Sun is sculpted by magnetic field lines that restrain the electrically charged solar plasma.
Stellar structure - Wikipedia
Convection is the dominant mode of energy transport when the temperature gradient is steep enough so that a given parcel of gas within the star will continue to rise if it rises slightly via an adiabatic process.

Although the Sun isn’t solid, it has three distinguishable regions that solar physicists refer to as the interior, the visible surface, and the atmosphere. The Sun’s interior is divided further into three parts – core, radiative zone, and convective zone.

2019年10月7日 · Convective zone This lies between the deeper, radiative zone and the photosphere. While the top layer is the same temperature as the photosphere (between 4500–6000 °C), the base of the convective zone reaches two million degrees Celsius. Plasma at the base of the zone is heated rapidly.

The convective zone is the outermost layer of the solar interior. It is a thick layer approximately 200,000 kilometers deep that transports energy from the edge of the radiative zone to the surface through giant convection cells, similar to a pot of boiling oatmeal.

It is traditional for purposes of discussion to organize the anatomy of the sun around the core and shells surrounding the core, these shells being referred to as the radiative layer (or zone), the convection layer, and the photosphere, which is the surface "layer" that we are able to observe.
