What Causes Auroras?

The video explains the phenomenon of auroras, starting with the basics of solar winds and Earth's magnetic field. It describes how the magnetic field protects Earth from solar plasma and how auroras are formed when charged particles hit the atmosphere near the poles. The video also covers the impact of solar storms on auroras and explains the different colors seen in auroras, which result from the interaction of solar particles with atmospheric gases like oxygen and nitrogen.

Describe the process that leads to the creation of auroras when solar particles hit the atmosphere.
