The layers of the Sun are divided into two larger groups, the outer and the inner layers. The outer layers are the Corona, the Transition Region, the Chromosphere, and the Photosphere, while the inner layers are the Core, the Radiative Zone, and the Convection Zone. There are four outer layers of the Sun, and the Corona is the outermost :// The manifestation of convection in deep layers of the Sun has been found in the dynamics of solar surface activity (Arkhypov, Antonov, and Khodachenko in Solar Phys. , 1, ). Abstract. As a preliminary step toward a complete theoretical integration of three-dimensional compressible hydrodynamic simulations into stellar evolution, convection at the surface and sub-surface layers of the Sun is re-examined, from a restricted point of Layers of the Sun Explained: Exploring Our Home Star Our Sun is a beautifully complex star. Keeping itself alive via nuclear fuel, the Sun is a vast system of layers and fascinating processes. But, while complex, understanding the Sun in general is simple and exciting! Let’s dive in and examine all the layers of the ://

  This graphic shows a model of the layers of the Sun, with approximate mileage ranges for each ://   In many stars both may operate: some regions of the interior may transport heat by convection and some by radiative transport. On the Main Sequence, a low mass star will have convection in its outer layers, like the Sun. If it's really low mass it will have convection all the way in! A high mass star will have convection only in its transport in strong magnetic fields slow convection and prevent hot plasma from entering the region. The light radiated from the Sun's surface reaches Earth in about 8 minutes. However, the energy of this light was released by fusion in the Sun's core about which of the following lists the "layers" of the Sun in the correct order? core, radiation The stagnant lid convection regime is typical for planets with a large viscosity ratio between the cold surface layers and the hot mantle interior of the order of at least 10 4 between the surface layers and the deep mantle. Viscosity decreases with depth in Mars because of the increase in ://

  Convection currents are evident in the sun. The granules seen in the sun's photosphere are the tops of convection cells. In the case of the sun and other stars, the   The photosphere is the visible surface of the Sun (Figure ). This is the region of the Sun that emits sunlight. It's also one of the coolest layers of the Sun—only about °C. Looking at a photograph of the Sun's surface, you can see that it has several different colors; oranges, yellow and reds, giving it a grainy ://   Convection occurs on a large scale in atmospheres, oceans, planetary mantles, and it provides the mechanism of heat transfer for a large fraction of the outermost interiors of our sun and all stars. Fluid movement during convection may be invisibly slow, or it This process, known as convection, sees this bright plasma rise to the surface in cells, where it then cools and sinks below the surface in dark lanes.
