Have Fun With The Layers Of The Sun!
Did you know that the sun has layers just like the earth? Well, I will tell you all about them! There are inner layers and outer layers too! Read on!
The most outer layer of the sun which is also the atmosphere is called the corona. Yes, the name of the much dreaded coronavirus is also the name of the atmosphere of the sun. But no worries as this layer is almost 2,000,000° Fahrenight and that high temperature will burn corona and then we can put corona in the dustbin🗑. The corona also traps hot plasma lines that will eventually hit Earth, mixing with the atmosphere and making the aurora borealis also called the northern lights.
The second layer of the sun is the chromosphere which is greek for colours sphere. Surprisingly, the temperature drops to 36000° F. Over here, hydrogen atoms radiate forming a red colour which the layer is named after. But this layer can not be seen on the other behind layers and you will need special equipment to see the chromosphere from Earth. But is sometimes in solar eclipses, the behind layers are hidden and the corona and the chromosphere can be seen clearly.
The third layer of the sun is the photosphere which I would take a photo of, if I could. This is because this layer of the sun is so bright that its name means light sphere and my photo will be unseeable, let alone how will I take it! On this layer, the first visible part of the sun is seen. Over here, the temperature falls even more to 6000° F and sunspots can also be seen which are random spots on the surface that are around 3600° F cooler than the rest of the layer.
These are the outer layers of the sun that make up the sun’s atmosphere:
In the next layer of the sun, we move on to one of the inner layers: The Convection Zone. In the convection zone, light is finally converted into heat. Convection is the fact that hot things rise and cold things sink. So in the Convection zone, huge bubbles called convention cells get heated up at the bottom of the layer so they rise to the top. As they rise, they cool down again so they sink to the bottom and the cycle repeats itself. This is why this layer is called the convection zone.
The next layer is the Radiative Zone. Over here it is very very very dense. Here, electromagnetic radiation, which is actually light, travels to the convection zone. The radiative zone is about 300891001 meters wide. Light can travel that much in 1 second but it is so dense that it takes several years for light to get past the Radiative zone.
And now the innermost layer: The Core!!
The core is like a giant nuclear factory, 313822080 meters long! Pressure and density are as strong as being deep underwater in the Marina Trench. In this extreme pressure and density, Hydrogen atoms smash together and form helium. Now the atoms become very unstable and release nuclear energy to become stable again, a process called nuclear fusion. The energy that reaches the Earth from the Sun has been generated from the Core. The core is 27000000° F. Well, that is definitely not ‘cool’!
