What makes lighting happen?

Answer 1

Clouds contain tiny crystals of ice and droplets of water,which move against each other. This can cause huge amounts of charge to build up in clouds . Ordinary,nothing happens due to this charge is great enough and the wind brings the clouds close together,the charge can jump from one cloud to another through the air. This electric discharge is called 'LIGHTNING'.

Answer 2

Lightning is produced in thunderstorms when liquid and ice particles above the freezing level collide, and build up large electrical fields in the clouds. Once these electric fields become large enough, a giant "spark" occurs between them, like static electricity, reducing the charge separation. The lightning spark can occur between clouds, between the cloud and air, or between the cloud and ground. As in the photo above, cloud-to-ground lightning usually occurs near the boundary between the updraft region (where the darkest) clouds are, and the downdraft/raining region (with the lighter, fuzzy appearance). Sometimes, however, the lightning bolt can come out of the side of the storm, and strike a location miles away, seemingly coming out of the clear blue sky. As long as a thunderstorm continues to produce lightning, you know that the storm still has active updrafts and is still producing precipitation. The temperature inside a lightning bolt can reach 50,000 degrees F, hotter than the surface of the sun. Objects that are struck by lightning can catch on fire, or show little or no evidence of burning at all.

Answer 3

Lightning is caused by the buildup of electrical charges in the atmosphere, typically in a thunderstorm. When the difference in charges becomes strong enough, a sudden discharge of electricity occurs between clouds, or between a cloud and the ground, creating the visible bolt of lightning.

Answer 4

By diffraction.
