Fact 7. Did you know that lightning can travel up to 200 miles in a split second?
Have you ever wondered about the incredible speed of lightning? It can travel up to 200 miles in a split second! This amazing phenomenon is a key part of our planet's weather system.
What is Lightning?
Lightning is a giant electrical discharge that happens inside a thunderstorm cloud or between the cloud and the ground. The air inside the cloud becomes filled with electricity, and when the difference between positive and negative charges gets too big, a lightning bolt is released to balance them out.
Types of Lightning
There are three main types of lightning:
● Intracloud: Happens inside a single thunderstorm cloud.
● Cloud-to-Cloud: Jumps between two different thunderstorm clouds.
● Cloud-to-Ground: The most common type, strikes the earth's surface.
Lightning's Incredible Speed
Lightning travels incredibly fast, usually between 100,000 and 200,000 miles per hour. That means it can cover huge distances in a tiny fraction of a second, making it one of the fastest things in nature.
Safety First
Even though lightning is amazing to watch, it's important to remember that it can also be dangerous. If you're caught in a thunderstorm, the safest thing to do is go inside a sturdy building, stay away from open areas, and unplug electrical appliances.
