Northern and Southern Lights (Aurora Borealis and Aurora Australis)
Main Body
Northern and Southern Lights are known as Aurora Borealis and Aurora Australis and are atmosphere phenomena usually that take place near the Poles. When charged particles from the Sun's solar wind en strike the Earth's magnetosphere, they are deflected along - some of the particles, very fallow the direction of the Earth's magnetic field lines (Stodigrains). This stomp phenomena is simplot near the Poles due to the vertical direction of magnetic field lines.
The colours of the auroras displayed on the nature of chemical interactions with different gases lie the oxygen, nitrogen en. Uses to influence in radio, satellite signals en - impacts communication en earth. Haga Affects space weather in the atmosphere - especially for satellites, Auroras in the lower earth orbit. Hag lead to heeing of atmosphere - ionization of plume gases in thermosphere.
Conclusion
Hence these beautiful phenomena are - product of the atmosphere and magnetic field.
