Question

Why does Earth have Auroras?

I'm not sure which subject this should be under, but this is a question on my science homework.

Answer 1

In the ionosphere, the ions of the solar wind collide with atoms of oxygen and nitrogen from the Earth's atmosphere. The energy released during these collisions causes a colorful glowing halo around the poles—an aurora.

Answer 2

Step-by-step explanation:

The reason for the occurrence of auroras is the bombardment of the shell of the Earth's atmosphere by charged particles ("solar wind"). These charged particles move towards the Earth along the magnetic field lines.
