ELI5: Explain Like I'm 5

Illinoian Stage

Hello there! Have you ever heard of something called the "Illinoian stage"? No? Okay, I'll explain it to you then!

So, a long time ago (like, thousands of years ago), the world that we live in looked very different. There were big sheets of ice covering a lot of the Northern areas, including parts of North America (which is where we live!).

The Illinoian stage refers to a specific time period during the last Ice Age when large parts of what is now Illinois and the surrounding areas were covered by these big sheets of ice.

During the Illinoian stage, the ice got really thick and slowly moved across the land, changing the way the landscape looked. It also caused changes in the climate and affected the plants and animals that lived there.

Scientists use things like rocks and dirt that were left behind by the ice, as well as the shapes of the land that were created by the movement of the ice, to study and understand this time period.

So basically, the Illinoian stage was a period of time when big sheets of ice covered Illinois and parts of the surrounding area, and it had a big impact on the environment and the way the land looked. Cool, huh?
