Why ist Michigan also called as great lakes state?

Michigan is called the "Great Lakes State" because it borders four of the five Great Lakes: Lake Superior, Lake Michigan, Lake Huron, and Lake Erie. This gives Michigan the longest freshwater coastline of any state in the United States, with over 3,200 miles of shoreline. Michigan is also home to several smaller inland lakes, making it a popular destination for fishing, boating, and other water sports.
