What causes the aurora borealis or northern lights to occur?

-streams of charged particles from the sun mix with earth's atmosphere
-light from the moon reflects on earth's atmosphere
-charged particles from the sun reflect off of the ice at the poles
-none of the above

the part i "agree with' is " it should not matter what color their skin is or what their cultural beliefs are." but for the main part i agree with it all or if cause now and days there are some people don't get the job cause there skin color and there beliefs and some times they don't even get the same repest as white people. we are all equal.
