At least once in your lifetime, you might have looked into the sky and wondered what causes lightning and thunder. From believing that lightning was a weapon of Zeus to thunderbolts invented by Athena, there are various ancient myths about lightning. But what are the actual causes of lightning in the sky? Here is the answer

In simple terms, lightning is a sudden electrostatic discharge between clouds or between the cloud and the ground. When the ground is hot, the air gets warm. The warm air rises and forms clouds. When the warm air meets the cold air, it rises even more and forms thunder clouds. This is why lightning is said to be closely related to thunderstorms. The cold air contains crystal-like particles like rain, ice, or snow inside clouds. When these particles move around, they bump and rub into each other, which causes an electric charge. Later, the entire cloud possesses electric charges. The upper part of the cloud accumulates lighter, positively charged particles and heavier, negatively charged particles sink at the bottom of the cloud. When the positive and negative charges grow, it causes lightning. Mostly, lightning happens within clouds, but it can also happen between the sky and the ground.
