Old Red Sandstone

Alright kiddo, have you ever seen a big rock? You know, the kind that's really hard and heavy? Well, some of those rocks are called sandstones. Sandstones can be different colors, like gray or even red!

Now, there's a special kind of sandstone that's called "Old Red Sandstone". It's called "old" because it's been around for a very long time - we're talking millions and millions of years!

A long time ago, this old red sandstone was formed by lots of small particles of sand and rocks being squished together by things like water and pressure. Over time, these particles turned into solid rock that we call Old Red Sandstone.

Scientists like to study Old Red Sandstone because it can tell us a lot about what the Earth was like a long, long time ago. They can even find fossils in Old Red Sandstone, which are the remains of plants and animals that used to live on the Earth a very long time ago!

So there you have it, kiddo - Old Red Sandstone is a special type of sandstone that's very old and can tell us a lot about what the Earth was like a long time ago.
