Answer 2

An aurora occurs when the Earth's magnetic field is overwhelmed by charged ions.

Step-by-step explanation:

The Earth acts as a huge bar magnet. Magnetic field surrounds the Earth. when the charged particles coming from the sun interact with the magnetic field, beautiful colors can be seen in the sky. These are known as auroras. The color depends upon the gas present in the atmosphere. The electrons of gain energy and jump to higher level and then release photons when return back to its level.
