How are the great lakes formed?

Fresh Water Lake

The basins of the great lakes of North America were probably scooped out thousands of years ago by ice age glaciers.

Nowhere else in the world is there a group of fresh water lakes so large as the Great Lakes of North America.

The Great Lakes were probably scooped out many thousands of years ago by ice age  glaciers.  During that time, much of North America was covered with a vast sheet of ice.

As the glaciers slowly pushed south, they gouged out the basins for these lakes, acting much like giant bulldozers.  Then the earth warmed and the ice melted back to the northern boundaries.

The water from the melting ice filled the Great Lakes for the first time.  Today, rain and snow and many streams bring water to them.

All the lakes except Lake Michigan are bordered by both the United States and Canada.  Lake Superior is the largest.  After Lake Superior come Huron, Michigan, Erie, and Ontario.

Special ships, called “lakers,” carry cargoes of oil, grain and iron ore across the lakes. – Dick Rogers
