Where on Earth can you find plasma? Ok, so not that 'where on earth', like literally - 'Where on Earth'.
Where on Earth, can you find matter in the 4th state, i.e. the plasma state?
 A: Plasmas are a common part of the world we live in.  The definition of plasma allows them to exist within an environment consisting mostly of bound atoms.
A variety of human technology creates plasmas. The type I hear plasma researchers reference most is a simple RF Plasma. This is perhaps the most direct way to use electricity to shake off the electrons from their atoms within a confined volume by using fast oscillating electromagnetic fields.
Nature also creates plasma.  An Aurora is certainly included.  Many less "exotic" plasma states are much more common.  A fire has a low population of the ionized species, but is still a plasma.  From the Wikipedia plasma article:

A: See Wikipedia for a list of available plasmas over there..! Or have a look below for the chart which shows variation of temperature and electron density in different plasmas..!

A quick Googling would've provided the answer. Common examples include     


*

*Lightning..!

*The Sun (from Core to Corona)

*Fluorescent Lights and Neon Signs

*Nebulae (Luminous Clouds in Space)

*The Solar Wind

*Primordial Fusion during the evolution of the Universe

*Magnetic Confinement Fusion Plasmas

*Inertially Confined Fusion Plasmas

*Flames as Plasmas

*Auroras (Northern & Southern Lights)

*Interstellar Space (It's not empty... It's a plasma)

*Quasars, Radiogalaxies, and Galaxies (Emit plasma radiation and microwaves)

*Large Scale Structures of Galaxies (Filamentary and magnetized..!)

*Dense Solid State Matter (When shocked by nuclear explosion or earthquakes which emit both visible light and radio waves)

A: Naturally ? Probably lightning 
A: Lightning, Arcing (Between electrodes or in high voltage power line), The every CFL lamp that you see around, Plasma TV, Halogen Lightning. Aurora, and I am sure i am missing few others.
A: Best example of plasma on earth is lightning. It's, natural. plasma exists at high temperatures. Those temperatures don't usually exist here. But, they do for a brief second in a bolt of lightning

A: Electric is a type of plasma.Lightning is electric.Lamps and bulbs are lighten up by electric.All are plasmas
