Have you ever seen a shooting star in the sky? A meteor is like a shooting star, but sometimes they can be big and heavy, like a big rock or a chunk of metal. When these big meteors fall from space, they can create a big explosion in the air before they even hit the ground. This is called a meteor air burst.
Think of it like this - Imagine you have a water balloon and you throw it really hard at the ground. The balloon will explode when it hits the ground. Now, imagine you throw the same water balloon really high up in the air, so high that it never actually hits the ground. Instead, it bursts in the air, because it can't handle the pressure of gravity pulling it down.
A meteor is the same way. When it falls from space into our atmosphere, the air around it creates a lot of pressure and heat, just like when you press your hand against a balloon or when you rub your hands together very quickly. This pressure and heat can cause the meteor to explode in the air, creating a big burst of energy that can be very bright and loud.
Sometimes a meteor air burst can be dangerous, especially if it happens over a populated area. The explosion can create shockwaves that can shatter windows, knock down buildings, and even hurt people. But most of the time, meteor air bursts are just really cool to watch from a safe distance, like a big firework show in the sky!
