How are the northern lights formed?
The liquid iron core present at the interior of our earth has created a magnetic field around it.Till then which has been subjected to massive bombardment with high energy solar radiation & other form of harmful cosmic rays. All these high energy charged particles are get trapped in van allen radiation belts & in addition get reflected by the earth’s magnetic field towards the pole where these particles interact with the earth’s atmospheric components in form of a visible energy called the northen lights.
