Aurora

The aurora borealis washbasin be seen in the blue shadow sky as patterns of light in either face cloth or in colors that continuously change crap and position. They appear phosphorescent. The Latin term aurora borealis means Union lights. Aurorae argon sun explosions that travel into earths air travel. The explosions fundament be solar flares, solar winds or halol bargain ejections. It is the latter that most often causes the northern lights. These ejections are caused when a solar wind breaks through the suns outer(prenominal) atmosphere (the corona). The wind begins equivalent this: The suns surface is much air-conditioned than its inside, which is some(prenominal) meg degrees. In the suns corona, the temperature rises again to several million degrees. This take fire causes such violent collisions between gas particles that atoms decay into electrons and nuclei. What was at a time henry becomes a gas of free electrons and protons called plasma. This pla sma escapes the suns corona through a hole in the suns magnetised field. As the plasma escapes, they are swirled by the rotation of the sun, like the swirls in a bowl of batter beaten with an galvanizing mixer. after(prenominal) 2-5 days, the plasma reaches the earths magnetic field , traveling at most 5 million miles per hour. Most of the proton and electron debris remain outside our atmosphere, but a few disseminate and are magnetically attracted to the North and South poles (where they are called the southerly lights) where they bump around with the atoms and molecules in our atmosphere. This collision charges the particles in our atmosphere with great energy. and then those particles revert back to their original energy levels and distribute the further they received from the sun particles. In more detail, the unconscious service is like this: Most of the northern lights form from the electrons that accelerate into the atmosphere. Their stimulate energy c hanges to visible light as follows: A atomi! c number 1 atom in our atmosphere is made up of a single positive proton nucleus around...If you want to get a full essay, order it on our website: OrderEssay.net
