What significant geographic features were created by glaciers in Michigan?

The option identifying the Great Lakes and smaller inland lakes as significant geographic features created by glaciers in Michigan is accurate. During the last Ice Age, glaciers covered much of North America, including Michigan, where their immense weight and movement shaped the landscape. As these glaciers advanced and later retreated, they carved out depressions in the earth, which eventually filled with water to become lakes.

Specifically, the Great Lakes, consisting of Lake Superior, Lake Michigan, Lake Huron, Lake Erie, and Lake Ontario, are some of the largest freshwater lakes in the world and were formed primarily by glacial activity. Additionally, numerous smaller inland lakes dot the Michigan landscape, many of which are also a direct result of glacial processes.

The other features listed, such as deserts and canyons, do not align with the effects of glacial activity in this region as glaciers typically create lakes and plains rather than arid landscapes or deep canyons. Swamps and marshes can occur in glacial depressions but are not the primary features attributed to glacial formation in Michigan. Mountains and valleys also do not describe the topography shaped by glaciers in Michigan, which is more characterized by flat plains and numerous lakes rather than rugged mountainous terrain.
