File:Lightning over Oradea Romania 3.jpg|[[Lightning]] is an example of plasma present at Earth's surface. Typically, lightning discharges 30,000 amperes at up to 100 million volts, and emits light, radio waves, and X-rays. Plasma temperatures in lightning might approach 30,000 kelvin (29,727&nbsp;°C) (53,540&nbsp;°F), or five times hotter than the temperature at the sun surface, and electron densities may exceed 1024 m−3.
