Although it’s faraway there, have you ever wondered from what parts does the Sun consist of? Well, if you are about to learn about the solar system especially about the Sun, we have collected for you the best media to help you learn it, the sun diagrams. The Sun is mostly just a ball of hydrogen and helium, it’s actually broken up into distinct layers. The layers of the Sun are created because the temperatures and pressures increase as you move towards the center of the Sun. The hydrogen and helium behave differently under the changing conditions. Just look at the first diagram below!
From the diagram above you can see that the Sun is usually divided up into three main regions: the Sun’s interior, the solar atmosphere, and the visible “surface” of the Sun which lies between the interior and the atmosphere. There are three main parts to the Sun’s interior: the core, the radiative zone, and the convective zone. The core is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur. Moving outward, next comes the radiative (or radiation) zone. Its name is derived from the way energy is carried outward through this layer, carried by photons as thermal radiation. The third and final region of the solar interior is named the convective (or convection) zone.
The diagrams above show that there is the boundary between the Sun’s interior and the solar atmosphere which is called the photosphere. It is what we see as the visible “surface” of the Sun. The photosphere is not like the surface of a planet; even if you could tolerate the heat you couldn’t stand on it. Every single second, the Sun fuses six hundred million tonnes of hydrogen into helium. How amazing!
