Lightning is a high intensity spark generated by an electric discharge between a cloud and the ground between different parts of the same cloud or two of them.

The electrical discharge occurs between them and, in general, the soil, which is positively charged. Thunder is the sound hoarse and rumbling produced by the electric shock as a result of overheating of the air surrounding the lightning (visual manifestation of the beam) at a temperature of 15,000 ° C.
