Aurora Borealis (Northern Lights)
A natural spectacle of incomparable beauty, the auroras are produced around the magnetic poles of the Earth by the activity of the Sun. Solar wind acts on the magnetosphere, which is a part of the exosphere. In general, the greater the solar wind, the more prominent the aurora. Auroras consist of luminous patches and columns of various colors. Depending on whether they appear in the north or south, they are called aurora borealis or aurora australis. The aurora borealis can be seen in Alaska, Canada, and the Scandinavian countries.solar wind = a stream of charged particles released from the corona(=the Sun's outermost atmospheric layer) altitude = height above sea level oscillate = to vary
