When does Aurora Borealis occur? What causes it?
How does the solar wind interact with the Earth's magnetic field to create Aurora Borealis?
The solar wind is made up of charged particles that are deflected by the Earth's magnetic field. Some of these particles get trapped in the magnetic field and create a ring of charged particles around the poles. When these particles collide with atoms and molecules in the atmosphere, they release energy in the form of light, creating the beautiful colors of Aurora Borealis.
