How does lightning occur . Answer in at least 15 lines.

 Lightning: 

Water from the sea evaporates and drifts upward due to the low density of the vapor, and forms clouds. During the upward journey, they acquire electric charge due to friction. These charges are accumulated in such a manner that the positive charges are accumulated on top of the cloud and negative charges are accumulated on the bottom. The air is an insulator of electricity. When two clouds come near, or the potential difference between the cloud and the ground is too high, then the air between the clouds or between the cloud and ground undergoes dielectric breakdown and conducts electricity. This flow of electricity is known as lightning.

When potential difference between the ground and the cloud or between two clouds exceeds a certain limit,lightning is produced in the form of arc.This arc suddenly heats the nearby air causing sudden expansion and contraction of the air resulting in a loud sound called thunder.Air turbulence strips electrons from molecules of air, creating electrically charged ions. When the ions become concentrated within a cloud, they cause a very high voltage, typically hundreds of millions of volts, to exist between that cloud and the ground or another cloud. The voltage causes an ionized path of air to form, along which a sudden discharge of a million or so amperes occurs, resulting in a very hot, bright arc. The heating of air within the arc causes it to expand and then contract very rapidly, generating very loud sonic waves which we hear as thunder.

Hope now you got your answer

Cheers!!!!!!!!!!!!

 due to clouds moving and rubbing against each other, the clouds get electrically charged and hence produce lightning
