Solar atmosphere and the solar interior
slideserve.com
- The Sun consists of several distinct layers, each with unique properties and processes. These layers fall into two main sections: the solar atmosphere and the solar interior. Or, since the interior layers are so large, the four layers of the Sun are its atmosphere, convective zone radiative zone, and core.

Oct 10, 2012 · This graphic shows a model of the layers of the Sun, with approximate mileage ranges for each layer: for the inner layers, the mileage is from the sun’s core; for the outer layers, the mileage is from the sun’s surface. The inner layers are the Core, Radiative Zone and Convection Zone.

Temperature: 6500 Kelvin at the bottom to 4000 Kelvin at the top Density: 2 × 10−4 kg/m3 It is the deepest layer of the solar atmosphere that we usually see from earth covering a distance of about 400 km from the center of the solar disk. Due to its low density, it is relatively transparent, resulting in the photosphere being regarded as the visual...
Temperature: 4000 Kelvin at the bottom to 8000 Kelvin at the top Density: 5 × 10−6 kg/m3 It is found above the photosphere at a distance between 400 km to 2100 km above the solar surface. The temperature of chromosphere gets hotter as we go further away from the sun. Due to its high temperature hydrogen emits light that gives off a reddish color, k...
Temperature: 8000 Kelvin at the bottom to 500,000 Kelvin at the top Density: 2 × 10−10 kg/m3 A narrow region covering a thickness of about 100 km between the chromosphere and the next adjacent layer called the corona. The temperature in this region is also found to increase sharply as we move further away from the core and hence the name transition...
Temperature: 500,000 Kelvin at the bottom to 1,000,000 Kelvin at the top Density: 10−12 kg/m3 It is the outermost layer of the sun’s atmosphere that we normally see during a total solar eclipse. It starts at about 2100 km above the photosphere and has no upper limit as it merges with the sun’s outer atmosphere. It is the hottest part of the solar a...
Apr 11, 2022 · The Sun, our star, has several layers beneath the visible surface: the core, radiative zone, and convective zone. These, in turn, are surrounded by a number of layers that make up the solar atmosphere.
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.
Jul 28, 2021 · Currently, astrophysics has a model of the solar structure made up of six layers divided into two groups: the inner and outer layers of the Sun. The sun's atmosphere comprises the only layers of the Sun that can be observed directly are the outer layers: the photosphere, chromosphere, and corona.
The different layers of the Sun The Sun, like other stars, is a huge spherical object made of hydrogen and helium. Its diameter reaches 1.400.000 km, or 109 times the Earth’s diameter; but is 4 times less dense than the Earth due to its composition. The Sun is not only made of the glowing gas that we see with a telescope. It has, exactly
