Heya !

Here's your answer !!


__________________________

CAUSE OF LIGHTNING

When two clouds at differnet heights having a huge amount of positive and negative static charges approach each other , electrons from the negatively charged cloud push their way through air so as to reach the positively charged cloud at different heights.

The air gets white hot and hence a dazzling bluish white streak of light is formed which is called lightning.
