Glaciers.
yes, it does
they carved them out
The Great Lakes and the Finger Lakes were carved by ice glaciation in the valleys. Lakes in Minnesota and Wisconsin were gouged out by glaciers and later filled with water from melting glaciers. Niagara falls was formed when the glaciers created dams on the rivers and changed the flow.
Land features, expecially the size of the great lakes, are generally formed by natural processes. In the case of the great lakes, they were formed by huge glaciers moving southward. Each lake represents where a glacier stopped moving. When the glacier melted away, there was a deep and wide hole left where its immense weight had carved into the Earth, and the melt water filled the hole.
