The Five Great Lakes
The Great Lakes are a chain of five enormous freshwater lakes in central North America. Their names are Superior, Michigan, Huron, Erie, and Ontario. A popular memory trick for remembering them is the word "HOMES," made from the first letter of each lake.
The Largest Freshwater System on Earth
Together, the Great Lakes form the largest group of freshwater lakes on Earth by total surface area. They hold a remarkable share of all the fresh surface water on the planet. Lake Superior, the biggest of the five, is so large it ranks among the greatest lakes in the world all on its own.
Shared by Two Countries
The Great Lakes sit right along the border between the United States and Canada. Four of the five are shared by both countries, with the border running through their waters. Only one, Lake Michigan, lies entirely within the United States. The lakes are connected to one another by rivers and channels, and they ultimately drain to the Atlantic Ocean. They are a vital source of drinking water, transport, and industry for the whole region.
