convection zone Region of the Sun's interior, lying just below the surface, where the material of the Sun is in constant convective motion. This region extends into the solar interior to a depth of about 200,000 km.

Convection Zone
a layer in a star in which convection currents are the main mechanism by which energy is transported outward. In the Sun, a convection zone extends from just below the photosphere to about seventy percent of the solar radius.

Convection zone
In the Sun's outer layer (down to approximately 70% of the solar radius), the solar plasma is not dense enough or hot enough to transfer the heat energy of the interior outward via radiation.

The Convection Zone

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.

Convection Zone
The region below a star's surface where energy flows outward by the rising of hot gas known as convection.

convection zone the region of a star's interior where energy is transported outward using bulk motions of rising hot gas and sinking cool gas. For the Sun, it is the region above the radiative zone.

5. In the solar convection zone, the gas is partly ionized. (Hint)
6. Convection involves cool gas rising toward the solar surface, and hot gas sinking into the interior. (Hint) ...

Convection can occur when there is a substantial decrease in temperature with height, such as in the Sun's convection zone.

They are confined to the interior of the sun below the convection zone (which extends from 0.7-1.0 solar radii), and are practically inobservable at the surface.

The Sun has several layers: the core, the radiation zone, the convection zone, and the photosphere (which is the surface of the Sun). In addition, there are two layers of gas above the photosphere called the chromosphere and the corona.

For example, it allows us to determine the radius of the base of the convection zone.

This pattern, known as the solar granulation, is caused by turbulence in the upper levels of the convection zone. Each granule is about 2000 km (about 1240 mi) across.

The combination of what takes place in the convection zone and the differential rotation of the Sun creates something called the solar dynamo. This phenomenon is the true origin of solar activity.

The rate of this energy flow determines the location and size of a crucial stellar region called the Convection Zone. The zone extends from near the sun's surface inward approximately 125,000 miles.

Much information has also been collected about the Sun's convection zone - the outermost layer of the interior of the Sun.

convection zone
The region of the interior of the Sun which lies just below the surface. Hot material is brought up to the surface and cooler material flows down towards the centre in a constant cycle.

Sunspots arise when strong magnetic fields inhibit the hot plasma from rising up through the underlying convection zone.

Winds are basically driven by Solar heating. As the adjacent (highly idealized) image indicates, Solar heating on the Earth has the effect of producing three major convection zones in each hemisphere.
