When was the Ice Age?
A time when glaciers covered Canada Alaska and part of Wisconsin.
The Ice Age began about 1,000,000 years ago. It ended about 10,000 years ago when the Earth got warmer.
What the glaciers covered
Wisconsin covered in glacial ice (notice the driftless area?)
What is a glacier?
A glacier is giant sheet of packed layers of ice and snow that can be over 1 mile thick. They moved slowly because of their great weight.
Do you see the person in the lower left corner?
What is glacial drift?
A combination of soil, sand, gravel and rock that the glaciers picked up from other places. Glaciers carry it to different places. It was land that was pushed from further north. It forms kettles and moraines.
Glacial drift piled up as a moraine
What are kettles and moraines?
Kettles are valleys that filled with water to form lakes that were formed by the glaciers.
Moraines are long low hills that were formed at the front edge of the melting glaciers.
