A good example is a puddle of water after a rainfall.
Why do we have lightning.
Lightning begins with a process that s less mysterious.
When the ground is hot it heats the air above it.
When air continues to rise the cloud gets bigger and bigger.
This warm air rises.
Nitrogen the dominant gas in the atmosphere is excited by this strong flow of energy its electrons moving to higher energy states.
In the early stages of development air acts as an insulator between the positive and negative charges in the cloud and between the cloud and the ground.
Lightning is an electric current.
It can go from the cloud to the ground.
Evaporation is the process by which a liquid absorbs heat and changes to a vapor.
Lightning is an electrical discharge caused by imbalances between storm clouds and the ground or within the clouds themselves.
When the opposite charges build up enough this insulating capacity of the air breaks down and there is a rapid discharge of electricity that we know as lightning.
The energy goes through the air.
Most lightning occurs within the clouds.
Lightning is visible as a flash of light because of both incandescence due to its high temperature it glows blue white and luminescence excitation of nitrogen gas in the atmosphere.
This lightning bolt of energy that is let out is called a leader stroke.
To make this electric current first you need a cloud.
