Which scenario most likely formed most large lakes in North America and Europe?

Most large lakes in North America and Europe were likely formed by glacial activity during the last Ice Age. As glaciers advanced and retreated, they carved out depressions in the landscape, which later filled with water. Over time, these glacial lakes became some of the largest in the regions, including notable examples like the Great Lakes in North America. Additionally, post-glacial rebound and sedimentation further shaped the lakes we see today.
