using diagram, explain how lightning occurs between a cloud and the ground , or within the same cloud or between two adjoining cloud
Answers
Explanation:
CAUSE OF LIGHTNING - DEFINITION
During thunderstorm, when a charged cloud passes over an uncharged cloud, uncharged cloud acquires opposite charge by induction and the two clouds attract. When they combine with each other, they produce a large amount of heat, light and sound also known as lightning. Lightning can occur between clouds or between cloud and ground.
ELECTRIC DISCHARGE DURING LIGHTNING - DEFINITION
Thunder clouds (rain clouds) carry electric charges and these charges separate out within the cloud. The lower portion of a cloud generally carries negative charges and the upper portion carries positive charges.
These charges inside the clouds build up. They cannot flow from one cloud to another or to the ground because the air between them acts as an insulator, but when huge amount of charges build up, the insulating property of the air suddenly breaks down.
As a result, an electric discharge takes place between two oppositely charged clouds or between a charged cloud and the surface of the earth.This causes the flash of lightning that we see in the sky.
