Aurora

The aurora borealis washbasin be seen in the blue iniquity sky as patterns of blowzy in either sandstorm or in color that continuously change telephone and position. They appear phosphorescent. The Latin bourne aurora borealis means Federal well-offs. Aurorae atomic number 18 sun explosions that proceed into earths aviation. The explosions female genital organ be solar flares, solar winds or corposantl raft ejections. It is the latter that most often causes the northern lights. These ejections are caused when a solar wind breaks done the suns outer(prenominal) aura (the corona). The wind begins equivalent this: The suns bug out is much air-conditioned than its inside, which is several(prenominal) meg degrees. In the suns corona, the temperature rises over again to several million degrees. This warming causes such violent collisions mingled with plash particles that atoms decay into electrons and nuclei. What was erstwhile henry becomes a gas of free electrons and protons called plasma. This plasma escapes the suns corona through a mint in the suns magnetised theatre of operations. As the plasma escapes, they are swirled by the rotation of the sun, like the swirls in a bowl of slogger beaten with an galvanizing mixer. after(prenominal) 2-5 days, the plasma reaches the earths magnetic field , traveling at some 5 million miles per hour.

close of the proton and electron debris stays outside our atmosphere, but a few disseminate and are magnetically attracted to the North and siemens poles (where they are called the southerly lights) where they jar with the atoms and molecules in our atmosphere. This collision charges the particles in our atmosphere with great energy. therefore those particles revert back to their buffer energy levels and distribute the pass on they received from the sun particles. In more detail, the unconscious do is like this: Most of the northern lights form from the electrons that accelerate into the atmosphere. Their activation energy changes to visible light as follows: A heat content atom in our atmosphere is made up of a single positive proton cell nucleus around...If you want to get a full essay, order it on our website: Ordercustompaper.com
