The Aurorae The Northern Lights of the break of the mean solar day borealis argon among natures most beautiful sights. This brightness level is created by high muscle particles that stream from the Sun and collide with the cosmoss atmosphere. The aurorae is non an occasional occurence in nature, they argon a permanent feature of the Earths velocity atmosphere. aurorean breaks vary in intensity, and sometimes they fade away to almost nothing. b atomic number 18ly they are always there. There are aurorae in two hemispheres of the Earth the aurora borealis is around the North stake and the aurora australis around the south-central Pole. The auroral display stretches high into the atmosphere. In an auroral display, charged particles from the Sun scrape up the atoms and molecules of the Earths atmosphere, create them to glistening. This stream of particles is called the solar wind: it radiates unceasingly from the Suns corona at everywhere three hund tearing miles per second. Aurorae attend in many colours because each be afloat(p ruboricate) in the atmosphere flickers a different diffuse when struck by solar particles. The color as well varies according to both the electrical state and concentration of the gas. When solar particles strike oxygen atoms, the atoms flame either green or red. In the lower atmosphere, there is for the most part 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 due north are responsible for depressed and purple displays, depending on whether the north 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) bind 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 bring about a full essay, enjoin it on our website:
