What is a significant result of changes to drainage patterns caused by glaciation?

Changes to drainage patterns caused by glaciation have significantly influenced the landscape, particularly in northern Canada, leading to the presence of numerous lakes. As glaciers advanced and retreated, they reshaped the land through processes such as erosion, deposition, and the altering of natural watercourses. This glacial activity carved out depressions and basins, which later filled with water, resulting in the formation of many lakes.

Northern Canada is particularly known for its abundance of glacial lakes due to the last Ice Age, which left behind a landscape dotted with these water bodies. This phenomenon is a direct consequence of glacial melt and the reshaping of the topography. Therefore, the presence of numerous lakes in northern Canada is a significant result of changes to drainage patterns caused by glaciation, showcasing the profound impact of these ancient ice sheets on the current geography of the region.
