Which of the following Great Lakes is not one of the five major lakes?

Lake Champlain is not one of the five major Great Lakes. The Great Lakes consist of Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario. These lakes collectively form the largest group of freshwater lakes in the world by total area and are vital to the geography and ecology of the region.

In contrast, Lake Champlain, although a significant body of water located between New York and Vermont, does not meet the criteria to be classified as one of the Great Lakes. It is much smaller in size compared to the major lakes, and it is often categorized separately as a distinct waterway, which highlights its unique ecological and recreational importance but removes it from the list of major Great Lakes.
