Answer:
From in to out Nucleus, photosphere, chromosphere, corona, radiant zone and convective zone
Explanation:
Nucleus: In the nucleus of the Sun take place the nuclear reactions that produce all the energy of the star, in it is reached a At a temperature of 14 000 000°C, everything is subjected to great pressure, where matter is transformed into energy at a rate of 14 500 000 tonnes every second and emitted in the form of gamma radiation.
Photosphere: It is the one that emits light and heat, its temperature is of 600grados centigrados, in her are the solar spots, the grains of rice and the protuberances, they are tongues of fire that rise to more than a million km of height and are observable in the total eclipses of sun on its crown. Literally, it is a sphere of light, the visible surface of the Sun.
It should be pointed out that when we say surface we do not refer, in this case, to a solid surface, since the photosphere is formed by a layer of gas.
Almost all the light received from the Sun comes from the photosphere, although the source of energy is much lower in the solar core. The photosphere is approximately 300 km thick and has an average temperature of 6,000 degrees.
Chromosphere: It is where the prominences and the solar flan take place. It is relatively thin with a thickness between 9 000 and 16 000 km. In spite of being very tenuous and considering that it is almost the vacuum, it exhibits a very well defined structure and from it the spicules are detached like threads that form complex patterns.
Corona: It is the external part of the Sun. It is one hundred thousand times more opaque than the photosphere. It is not really spherical, as it oscillates, undulates and has changes in its form due to the interaction of the plasma that forms it with the magnetic field of the Sun. The corona is only visible with the use of the coronagraph or during eclipses. The gases escaping from the corona give rise to the Solar Wind.
Radiant Zone: A zone where highly compressed gases receive energy from the gamma radiation produced in the Sun's core. This radiation is not completely absorbed by the atoms that form the gases but bounces off of them, is partially absorbed and dispersed which produces a decrease in their wavelength and is transformed into X and ultraviolet radiation.
Convective zone: In this zone the gases of the Sun have a thermal gradient sufficient to produce convective movement. As the gases are colder, they are able to absorb the photons coming from the radiant zone and by means of convection they transmit the energy to the photosphere from where it is emitted to the outside, this produces a cooling of the gases that descend again until they absorb again the energy of the radiant zone.
