Five Great Lakes of North America are Superior, Michigan, Huron, Erie and Ontario, situated between the United States and Canada. The lakes are joined together through rivers and straits forming a huge system of waters, that plays an important part in transportation, trade and even settlement over centuries.
Their shores host major cities, diverse ecosystems, and support over 40 million people with drinking water, recreation, and economic activities.
Lake Superior
Lake Superior is the largest and deepest among all, that has an approximate area of 31,700 square miles and a maximum depth of 1,333 feet. It contains more water than all the other four combined and it is famous for its cold, clear waters and its rocky shores.
Lake Michigan
Lake Michigan is the only Great Lake, which is fully located in the U.S.
It is the third biggest in size and sustains big cities such as Chicago. Hydrologically it is linked with Lake Huron through the Straits of Mackinac.
Lake Huron
Lake Huron, second biggest in the area of surface area, includes thousands of islands including the largest freshwater island in the planet; Manitoulin Island. It plays a critical role in shipping, fisheries and recreation.
Lake Erie
Lake Erie is warmest and shallowest and as such is very productive to fishers but in danger of pollution and algal bloom.
It has densely populated and industrialised shores.
Lake Ontario
The smallest lake in size is Lake Ontario. It lies on the eastern part of the chain that empties into the Atlantic Ocean through the Saint Lawrence River and one of the major routes of shipping and trade activities.

What makes the Great Lakes unique?
Largest freshwater system in the world by surface area
The Great Lakes constitute the largest collection of freshwater lakes in the world in terms of surface area totalling more than 94,000 square miles. They hold an approximate volume of 21% of the planet earth in terms of fresh water and thus act as paramount resources of fresh water all around the world.
The lakes contain about 5,439 cubic miles of water with the Lake Superior having much more water than all other four lakes.
Landlocked seas having oceanic features
The lakes are very large and deep and thus instead of acting like all the common lakes, they act more like inland seas. They have breaking waves, powerful moving current, and far away horizons. The lakes also affect the regional climate such as the lake-effect snows that causes decentralized snows along the lakes.

Geological formation and age
Great Lakes were created in the last Ice Age 10,000 to 20,000 years ago as a result of glacial operations. Large glaciers left deep valleys that were filled up by meltwater as glaciers melted. These basins of the lakes are linked together, and thus constitute one drainage system dropping down from the basin of Lake superior.

Economic and cultural significance
The Great lakes area has a $6 trillion regional economy that forms millions of jobs through recreation, shipping and industry which is dependent on lakes. The lakes are part of the local culture and the cultural identity of the region itself as they have long history and their own lifestyle associated with their existence.
