The Great Lakes are important to the United States because it allows the transportation of cargo such as iron ore to travel by sea to the several States and Canada that border these lakes.
The Great Lakes are connected to the ocean through the St. Lawrence Seaway, a system of locks and canals that allows ships to travel from the Great Lakes to the Atlantic Ocean.
The retention time for each of the Great Lakes is different, and Lake Superior has the longest retention time of all the Great Lakes. When a drop of rainwater lands in Lake Superior, it takes over 200 years for it to pass through the Great Lakes to the Atlantic Ocean. Once it leaves the Great Lakes system, it has to travel though the St. Lawrence River on its way to the ocean.
The city with the busiest shipping port on the Great Lakes is Duluth, Minnesota. Its port handles a wide variety of cargo, including iron ore, coal, grain, and general cargo.
You could travel through the Great Lakes to get from certain points in New York to certain points in Minnesota.

Yes! All of the great lakes are interconnected. Between L.Erie and L.Ontario is a river that has Niagara falls, but there is a lock system that goes around the falls that the ships use to navigate. This is true for rivers between the other great lakes.
