Scientists call the ionosphere an extension of the thermosphere. So technically, the ionosphere is not another atmospheric layer. The ionosphere represents less than 0.1% of the total mass of the Earth's atmosphere.
In the atmosphere Auroras usually occur in the ionosphere (the highest part of the atmosphere, between the thermosphere and the exosphere. The ionosphere gets its name because it is ionized by solar radiation.). We typically see auroras only in high-latitude areas above about 50 degrees (north or south).he Aurora Borealis and its southern counterpart the Aurora Australis are formed high in the atmosphere in the ionosphere, which is sometimes considered as part of the thermos â¦ phere, the outermost actual atmosphere.
