Answer 2

The solar winds have been heated so hot that almost all are ionized ,there are 2 that are important. Alfa particles are nounal atoms blown off the sun that have lost electrons,making them positive charged and will be attracted to the south pole. Then there is the beta particle which is free electrons and are negative charged,and attracted to the north pole. The solar winds encountering the magnetic field and focus the Pericles on the poles. this is the holes at the poles that the environmentalist want u to think that it was because of the CLC"s
Is u need more just ask

The aurora is now known to be caused by electrons of typical energy of 1-15 keV, i.e. the energy obtained by the electrons passing through a voltage difference of 1,000-15,000 volts. The light is produced when they collide with atoms of the upper atmosphere, typically at altitudes of 80-150 km. It tends to be dominated by emissions of atomic oxygen--the greenish line at 557.7 nm and (especially with electrons of lower energy and higher altitude) the dark-red line at 630.0 nm. Both these represent forbidden transitions of atomic oxygen from energy levels which (in absence of collisions) persist for a long time, accounting for the slow brightening and fading (0.5-1 sec) of auroral rays. Many other lines can also be observed, especially those of molecular nitrogen, and these vary much faster, revealing the true dynamic nature of the aurora.

St. Elmo's fire is an electro-luminescent corona discharge caused by the ionization of the air during thunderstorms inside of a strong electric field. Although referred to as "fire", St. Elmo's fire is in fact a low density, relatively low temperature plasma caused by massive atmospheric electrical potential differences which exceed the dielectric breakdown value of air at around 3 megavolts per meter.
