The Aurorae- what causes the beautiful light displays. What impact does it have on Earth?

The Aurorae The Northern Lights of the break of the mean solar day borealis argon among natures most beautiful sights. This cloudless is created by high energy particles that stream from the Sun and collide with the balls atmosphere. The aurorae is not an occasional occurence in nature, they argon a permanent feature of the Earths speed atmosphere. aurorean breaks vary in intensity, and sometimes they fade away to almost nothing. scarcely they ar always there. There are aurorae in both(prenominal) hemispheres of the Earth the aurora borealis is around the North celestial pole and the aurora australis around the in the south Pole. The auroral display stretches high into the atmosphere. In an auroral display, charged particles from the Sun switch the atoms and molecules of the Earths atmosphere, create them to glistening. This stream of particles is called the solar wind: it radiates unendingly from the Suns corona at everywhere three hund tearing miles per second. Aurorae bug out in many colourize because each be directionless in the atmosphere cauterizes a different alter when struck by solar particles. The color also varies according to both the electrical state and slow-wittedness of the gas. When solar particles strike oxygen atoms, the atoms glow either green or chromatic. In the lower atmosphere, there is more often than not a green glow because the concentration of oxygen atoms is high. In the upper atmosphere there are fewer oxygen atoms.

The rate of strike between oxygen atoms is less, to red auroral display predominate. Particle collisions with northward are responsible for blasphemous and purple displays, depending on whether the nitrogen atoms are charged (ionized) or not. Although aurorae are ever-present, they are also ever-changing. Satellites such as the IMP-8 (Interplanetary Monitoring Platform) virgule monitored the solar wind. From their observations we know that aurorae are at their most spectacular when the solar wind blows ferociously enough to... If you want to ask a full essay, enjoin it on our website: Orderessay
