Definition of Parts of the Sun

The sun is a star singularas it provides light and Energy necessary for life on our planet to be possible. If it did not exist, the Earth would not have life. On the other hand, the Sun is the axis of our planetary system. All the planets revolve around him by force gravitational force that it exerts on them.

His composition

At its center the Sun has a powerful "nuclear reactor" in which temperatures of 15 million are produced. degrees centigrade and where oxygen is transformed into helium in a continuous chain reaction. When hydrogen nuclei fuse to produce helium nuclei, there is a small loss of mass and that matter is discharged as energy that provides the brightness solar we perceive.

At its core it has a great density, specifically it is ten times more dense than lead. The energy discharged there takes about 10,000 years to reach the surface. As for his compositionIt has 70% hydrogen, 28% helium and 2% heavy elements, mainly iron. Therefore, it is not a solid surface.

Different solar layers

The Sun includes six differentiated layers and all of them work as a harmonic whole to provide light and heat. Each layer affects the others producing the necessary stability so your dough stays together and compact.

The layers include an inner core, a radiant zone, a convection zone, a photosphere, a chromosphere, and a corona.

When observing it from the Earth we appreciate the photosphere and the rest of the layers constitute the inner zone of the Sun. The layers below its surface are denser as the depth increases. On the other hand, the layers are hotter as the depth increases because the Sun's heat takes place in the core and subsequently flows outwards.

Each of its layers has a function in the production of heat. The core area keeps all the gas that surrounds it and in this way its collapse is avoided. The radiant zone and the convection zone maintain pressure against the core. The photosphere is the layer from which the Earth receives light and heat. The chromosphere emits most of the light in the ultraviolet zone of the spectrum. Finally, the crown allows distribution of light and heat that reach Earth and the other planets through solar winds.
