How do aurora borialus occur?

In: Astronomy, Atmospheric Sciences, Aurora Borealis and Aurora Australis [Edit categories]

Answer:

Along with light and heat, the sun sends out large amounts of radiation- enough to fry our little planet and leave a scorched ball of dust behind. However, our magnetic field creates a type of shield that averts the majority of this radiation. Towards the poles, the 'shield' is less effective, and smaller amounts of the more energetic radiation particles pass through. When these enter the atmosphere, they leave bright trails behind them, which we can see as the auroras.
