What causes lightning?
उत्तर
Due to friction from winds, clouds collide with each other and get electrically charged during a thunderstorm (bundles of small water droplets and ice particles form a thunderstorm).
The upper part of the cloud is usually positive while the lower part of the cloud gets usually negatively charged.
A sudden movement in the cloud causes this electrical charge to discharge in the form of lightning.
