The Great Lakes were formed through a combination of glacial activity and geological processes during the last Ice Age, approximately 14,000 years ago. As glaciers advanced and retreated, they carved out deep basins in the landscape, which later filled with meltwater. The lakes we see today—Superior, Michigan, Huron, Erie, and Ontario—are interconnected and form the largest group of freshwater lakes in the world by surface area. Over time, natural processes and human activity have shaped their ecosystems and water levels.

The Great Lakes are a collection of five freshwater lakes, The Great Salt Lake is one saltwater lake. The Great Lakes are much larger than the Great Salt Lake. (The Great Lakes cover 80,545 square miles, the Great Salt Lake covers between 1,000 and 3,000 square miles, depending on the rainfall.)
