How is Lightning Formed Lightning is a bolt of electricity between the sky and the ground. A single bolt has enough power to light hundred lamps for a day. Lightning can strike people end even kill them. Lightning also starts hundreds of forest fires every year. Inside the big dark thundercloud on a stormy day are millions of tiny droplets of ice. These collide with each other all the time, creating electric charge (a small amount of electricity). In no time, the cloud gets filled up with charges. Electric charge are neither positive nor negative. When negative charges from the bottom of the cloud and positive charges of the ground meet, a flash is seen. This flesh is actually the path of the electrical charges. All this happens in a fraction of a second. Lightning heats up the air around it to temperatures up to 30,000 degrees Celsius. This is more than five times hotter than the surface of the sun when hair is heated so quickly, it expands and contracts violently, much like a balloon bursting. The explosion is heard as thunder. Lightning and thunder happen at the same time, but why do we always see lightning first and hear thunder later? This is because light travels almost a million times faster than sound. 1. What is the effect of lightning strikes?
