Lightning Explained Science Learning Hub Vrogue Co Lightning explained. lightning is a large scale natural spark discharge that occurs within the atmosphere or between the atmosphere and the earth’s surface. on discharge, a highly electrically conductive plasma channel is created within the air, and when current flows within this channel, it rapidly heats the air up to about 25,000°c. A lightning discharge is normally measured in kilometres, so it’s a gigantic electrical spark carrying a gigantic current zapping the atmosphere – heating it up and causing this tube of plasma to run from the top of the thundercloud down to the ground. in order to form lightning, you need to have a large electric field. so what happens in.
Lightning Explained вђ Science Learning Hub Image. add to collection. tweet. rights: the university of waikato te whare wānanga o waikato published 29 april 2014 size: 140 kb referencing hub media. the main steps in the production of a lightning bolt are shown. a stepped leader grows down from the cloud until it contacts a leader moving up from the ground. a return stroke is then generated. Lightning explained lightning is a large scale natural spark discharge that occurs within the atmosphere or between the atmosphere and the earth’s surface. on discharge, a highly electrically conductive plasma channel is created within the air, and when current flows within this channel, it rapidly heats the air up to about 25,000°c. Lightning causes thunder. in a thunderstorm, lightning occurs when an electrical discharge happens within or between clouds or between a cloud and the ground. charged dust particles work like charged ice particles in volcanic eruptions and heat lightning. while the two events occur simultaneously, you see lightning before you hear thunder. In the united states alone, lightning hits the ground 25 million times a year. lightning is a gigantic electrical spark. a spark that can be 5 miles (8 kilometers) long. it would take up to 80 million car batteries to equal the power of one thunderbolt. a single lightning flash has enough energy to light a 100 watt bulb for three months!.

Lightning facts. certain conditions with clouds make lightning. lightning is really a discharge of static electricity between the clouds and the ground or between different clouds. lightning is unpredictable so it is very dangerous to people and animals. in deserts or during dry hot weather, lightning often occurs without any rain. When you’re in the car, you might go 60 miles in an hour, so lightning is that much faster than a car. as the lightning shoots through the air, it heats that air up because lightning is hotter than the sun. when air gets that hot, that fast, it explodes, which is why you hear thunder after you see lightning. why is the thunder always after.
