What is lighthning?

Answer 1

lightning occurs because of a sudden gain of electrostatic discharge by clouds. It is uncertain how exactly the electrical charge forms but it is known that it is caused when clouds crash into each other. Heavier molecules in the cloud carry the charge to the bottom of the cloud.

A lot of people think lightning travels either from the ground up or from the sky to ground. Both are true depending on the charge (whether is + or -).

There is also cloud to cloud lightning which acts the same way. When the charge is great enough to move through air resistance, it moves or "strikes"

it is still sort of one of those 'mysteries'

Answer 2

Lightning is a natural electrical discharge caused by imbalances between storm clouds and the ground. It is typically accompanied by thunder and can be dangerous due to its high voltage and heat. Lightning is a common occurrence during thunderstorms.
