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.

Sep 22, 2022 · 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.
Layers of the Sun – Diagram and Facts - Science Notes and Projects
Feb 3, 2024 · 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.

Jan 23, 2013 · 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.
15.1 The Structure and Composition of the Sun - OpenStax
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.
Convection - Wikipedia
The convection zone of a star is the range of radii in which energy is transported outward from the core region primarily by convection rather than radiation. This occurs at radii which are sufficiently opaque that convection is more efficient than radiation at transporting energy.
Convective zone - (High Energy Density Physics) - Fiveable
The convective zone is a layer within a star where energy is transported outward primarily through the process of convection. In this layer, hot plasma rises toward the surface, cools, and then sinks back down to be reheated, creating a continuous cycle.

Oct 7, 2019 · 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 Sun’s Convection Zone: Where Heat Rises And Energy Flows
Jun 18, 2024 · The convection zone occupies the outermost layer of the Sun, stretching from just beneath the visible surface to about 200,000 kilometers into the solar interior. It is an ocean of plasma, an ionized gas that relentlessly churns and swirls, carrying with …
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.
