Plasma is a state of matter that results from one of the other three classical states having undergone an appreciable degree of ionization. It thus consists of a significant portion of charged particl
Lightning as an example of plasma present at Earth's surface: Typically, lightning discharges 30 kiloamperes at up to 100 megavolts, and emits radio waves, light, X- and even gamma rays. Plasma temperatures can approach 30000 K and electron densities may exceed 1024 m−3.
