Question

What is aurora Boriolis ?? Explain

Answer 1

» During a solar flare, a large number of electrons and protons are ejected from the sun. Some of them get trapped in the earth's magnetic field and move in helical paths along the field lines. The field come closer to each other near the magnetic poles. Hence, the density of charges increases near the poles. These particle collide with atoms and molecules of the atmosphere. Excited oxygen atoms emits pink light. This is called Aurora Boriolis in physics.
