Final answer:
Lakes Ontario and Superior were not formed by glaciers, but by tectonic movement and other geological processes.
Step-by-step explanation:
The glacier theory does not work for the formation of Lakes Ontario and Superior because they were not formed by glacier activity, but instead by different geological processes. The Great Lakes formed as a result of tectonic movement, specifically the movement of the Earth's crust and the melting of glaciers that resulted in large basins being filled with water. The glaciers helped shape the landscape of the Great Lakes region, but they did not directly form the lakes themselves.
