The faint yellow area shown above the north pole represents gas lost from Earth into space; the green area is the aurora borealis-or plasma energy pouring back into the atmosphere.[2]අර්ථ දැක්වීම[සංස්කරණය]Although a plasma is loosely described as an electrically neutral medium of positive and negative particles, a definition can have three criteria:[3][4][5]The plasma approximation: Charged particles must be close enough together that each particle influences many nearby charged particles, rather than just interacting with the closest particle (these collective effects are a distinguishing feature of a plasma). The plasma approximation is valid when the number of charge carriers within the sphere of influence (c
