How lighting in the sky appears?
Asked by Unnat Lal | 11 Feb, 2012, 08:24: PM
answered-by-expert Expert Answer
 lightning is really not much more than a very large and powerful spark. It is caused by a discharge of electrical energy that has built up inside a thundercloud. During a thunderstorm, processes involving things such as vertical winds and different-sized water droplets cause electrical charges to build up in various parts of the cloud. When these charges become powerful enough, they discharge, causing a stroke of lightning.
