The subject of these auroras and related issues such as the aurora borealis and aurora australis are of great significance and importance, and in order to come to a clearer and more knowledgeable understanding of these issues, the related information must be addressed thoroughly. The aim of this paper is to discuss all of this, as well as explain how each of the sub-subject matters are related and correlated. This is what will be dissertated in the following.
Auroras are caused by high energy particles from the solar wind that are trapped in the Earth's magnetic field. These particles, as they spiral back and forth along the magnetic field lines, come down into the atmosphere near the north and south magnetic poles where the magnetic field lines disappear into the body of the Earth. "The delicate colors are caused by energetic electrons colliding with oxygen and nitrogen molecules in the atmosphere. This excites the molecules, and when they decay from the excited states they emit the light that we see in the aurora." (Csep, n.d.). ...Show more
