How did ice age glaciers form lakes in North America and Europe?

Ice age glaciers formed lakes in North America and Europe through processes of erosion and deposition. As glaciers advanced, they carved out depressions in the landscape, creating basins that would later fill with water as the glaciers melted. Additionally, meltwater from the glaciers contributed to the formation of lakes, while glacial debris often blocked river valleys, leading to the creation of natural dammed lakes. This interplay of glacial movement and melting resulted in the numerous lakes found in these regions today.
