How Does The Canadian Shield in Ontario Work?

The Canadian Shield in Ontario is like a giant rocky playground that covers most of the province.

Imagine you're playing outside and you dig into the ground with your hands, that's kind of what happens with the Canadian Shield. It's made up of really old rocks, some so old they were formed millions of years ago, when the Earth was still getting its shape. These rocks are hard and tough, like the skin on your hand.

If you walk across the Canadian Shield, it feels like walking across a bumpy floor, that’s because the ground is made up of hills and valleys formed by these old rocks. Sometimes there are lakes nearby, which act like little pools in the playground, making it even more fun to explore.

Because the Shield is so rocky, it helps shape the land around it, trees grow on top of it, rivers flow through it, and animals live all over it. It’s not just a place to play; it's like a big natural house that many things call home.
