Do you like going outside and seeing big, tall things around you? Scotland has some really big, tall things called mountains and hills! Mountains are the biggest and tallest, like big giants that go very high up into the sky. Hills are a little smaller but still bigger than the normal ground we walk on.
Mountains and hills are made of something called rocks that are piled up on top of each other. The rocks of Scotland's mountains and hills are really old, like even older than your grandparents! They were made millions of years ago when the earth's crust (which is like the earth's skin) moved around a lot and pushed the rocks up high into the air.
Sometimes, you might see snow on top of Scotland's mountains. This is because the air up there is colder than the air down below. Also, people can go hiking and climbing on Scotland's mountains and hills. But they have to be very careful and make sure they have the right equipment because it can be dangerous.
So, in summary, Scotland has big, tall things called mountains and hills that are made of old rocks piled up on top of each other. They can have snow on them and people can go hiking or climbing on them.
