Auroras are very beautiful and I'd like to ask why can we only see them in the North and South poles of the Earth?And why do Auroras change color like a light display?

They are formed because of the magnetism in the atmosphere.And the magnetic poles are a few miles away from the north pole and south pole.soooo does that answer your question?

It does, kinda...But why do they change color like frequency waves?

The sun produces them. Blue is produced most.

Also called th Aurora Borealis.Or the Northern lights, because they are only found in the northern hemisphere.
It is usually found in the ionosphere.
Aurorea are not JUST blue. They can be any color, as caused by the suns energy, which is all colors.
The aurora is caused by a collision of atoms, protons, and electrons.

Ok...auroras are caused when solar wind (subatoic prticles launched form the sun) hit the magnetosphere and that generates light. They are only seen at the north and south poles because the magnetic field is shaped annoyingly.
How do i explain it...think of lines coming out of the north pole which then wrap around the earth heading towards the south pole, which then go back into the south pole.If you drew the diagram correctly, you'll see that near the poles the magnetic field is very close to the earth therefore we can see wonderful auroras!!!
They change colour depending on the subatomic particles, and the intensity of the wind.
