Question

What causes the Aurora Borealis?

Answer 1

The Sun's magnetic field  throws charged particles from its atmosphere out into space. As these particles near the Earth they are pulled in by its magnetic field , which pulls them down to the magnetic poles. Before they can reach the Earth, the charged particles hit the Earth's atmosphere  and collide with the gases found there. The reaction between those particles and the gases creates energy, and the energy is given off as light - the Northern Lights.
