Impact event

Sometimes, big rocks or icy comets from space zoom towards Earth. When they hit, it's called an impact event! These space visitors can be traveling super fast, like a race car on steroids.

Even if they are small, they can make a big splash. If a really giant rock hits, it can cause huge changes to the land, like digging a giant hole called a crater. These craters are like scars on the planet's face!

Impact events have been happening for billions of years, even before dinosaurs! Scientists look at craters on the Moon and Earth to see how often these crashes happen. A super famous crash happened 66 million years ago, and some people think it helped make the dinosaurs disappear.

It's like a cosmic history book written in rocks. These events have shaped our planet and even helped create the Moon we see in the sky!

These big crashes might sound scary, but they've actually helped life on Earth! Some scientists think that rocks from space might have brought water and the tiny building blocks needed for life to start. Other crashes, like the one that might have wiped out the dinosaurs, also made room for new kinds of animals, like mammals, to grow and become super successful.

So, even big disasters can lead to new beginnings!

We've seen some amazing impact events! In 1908, a giant explosion happened in Siberia, Russia, knocking down millions of trees. More recently, in 2013, a meteor exploded over Chelyabinsk, Russia, and lots of people got hurt by flying glass.

Scientists are even learning how to push asteroids away from Earth, like a game of cosmic billiards, to keep us safe. It shows we're learning to understand and even protect ourselves from these space visitors.
