  2. NOx - Wikipedia

    en.wikipedia.org/wiki/NOx

    With 1.4 billion lightning flashes per year, multiplied by 7 kilograms per lightning strike, they estimated the total amount of NO x produced by lightning per year is 8.6 million tonnes. However, NO x emissions resulting from fossil fuel combustion are estimated at 28.5 million tonnes. [14]

  3. Fulgurite - Wikipedia

    en.wikipedia.org/wiki/Fulgurite

    Typical broken fulgurite sections. Fulgurites (from Latin fulgur 'lightning' and -ite), commonly called "fossilized lightning", are natural tubes, clumps, or masses of sintered, vitrified, or fused soil, sand, rock, organic debris and other sediments that sometimes form when lightning discharges into ground.

  4. Nitrogen fixation - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_fixation

    Nitrogen can be fixed by lightning converting nitrogen gas (N 2) and oxygen gas (O 2) in the atmosphere into NO x (nitrogen oxides). The N 2 molecule is highly stable and nonreactive due to the triple bond between the nitrogen atoms. [75] Lightning produces enough energy and heat to break this bond [75] allowing nitrogen atoms to react with ...

  5. Lightning - Wikipedia

    en.wikipedia.org/wiki/Lightning

    Lightning is a natural phenomenon, more specifically an atmospheric electrical phenomenon. It consists of electrostatic discharges occurring through the atmosphere between two electrically charged regions, either both existing within the atmosphere or one within the atmosphere and one on the ground, with these regions then becoming partially or wholly electrically neutralized.

  6. Plasma (physics) - Wikipedia

    en.wikipedia.org/wiki/Plasma_(physics)

    Plasma is called the fourth state of matter after solid, liquid, and gas. [ 16 ] [ 17 ] [ 18 ] It is a state of matter in which an ionized substance becomes highly electrically conductive to the point that long-range electric and magnetic fields dominate its behaviour.

  7. Atmospheric electricity - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_electricity

    Cloud-to-ground lightning. Typically, lightning discharges 30,000 amperes, at up to 100 million volts, and emits light, radio waves, x-rays and even gamma rays. [1] Plasma temperatures in lightning can approach 28,000 kelvins. Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet).

  9. List of light sources - Wikipedia

    en.wikipedia.org/wiki/List_of_light_sources

    This is a list of sources of light, the visible part of the electromagnetic spectrum.Light sources produce photons from another energy source, such as heat, chemical reactions, or conversion of mass or a different frequency of electromagnetic energy, and include light bulbs and stars like the Sun. Reflectors (such as the moon, cat's eyes, and mirrors) do not actually produce the light that ...
