They are called aurora borealis or northern lights. What causes them and why dont we see them down here.?

Question

From the movie the core

Please and thanks

ps i gotta get this answered quick because its for my project

Answer 1

good luck with that

Answer 2

Due to the solar wind, especially during times of intense sunspot cycles, and intense coronal mass ejections there will be more outputs of highly energized particles in the solar wind.

However Earth's own magnetic field is in the path of the solar wind, causing it to be diverted. The magnetic field however will capture some of these energetic particles and these particles will travel along the lines of force to the magnetic focii concentrated at the north and south poles. This is of course like the poles of natural and manmade magnets (which acquired the north and south pole naming convention from the way they can align with the earth's own poles-- i.e. in compasses)

Since the Earth's magnetic field will divert such large quantities of energized particles towards the poles they will become concentrated there allowing intreactions to take place between the particles and the concentrated magnetic fields, causing the intence and beautiful displays to occur. There are times however few and far between where the intense coronal mass ejections are strong enough to cause more wide spread displays where the effects can be seen into lower latitudes (not just in the north or south pole regions).

Answer 3

Aurora Borealis, or Northern lights are a delightfully beautiful curtains of light displayed close the the top of our earth, and the aurora australis, southern lights, at the bottom. Respectfully at the North and South poles.Our magnetic field on earth blocks solar wind and flares for the sun, protecting us from being fried to oblivion. Also called the magnetosphere. But, near the top and the bottom of our earth, there is a little gap in the Magnetosphere(magnetic field) called polar cusps, and through these some solar matter gets in close in our atmosphere, mingling with the atmospheric gases, causing this display of light. Again, this happens near the polar cusps or gaps in the magnetosphere, which are :::: **ding** --- right near the north and south poles::: the aurora borealis-- in the north, the aurora australis in the south.

I hope this was somewhat informative Good Luck!!!
