The Great Lakes are major landforms in America. They are giant freshwater lakes located in the
northern region of American. In addition to their beauty, the lakes not only provide water for
consumption but also serve for transportation, recreation, power generation, and many other uses.
How were these landforms created? Well I am going to tell you all about the many different ways
people believe it was made, and the way it was made.
First I will begin with how people thought it was created with lava. About a billion years ago there
was a fracture in the earth’s crust running from what is now Oklahoma to Lake Superior. The boiling
hot magma will erupt and can harden over time and make strange geological forms, thus being the
basin of the lakes. The tiny corral

This is evidence showing why lava could not have been the reason why The Great Lakes were
formed.
Next, I will talk about how some people believed that water created The Great Lakes. When water
started to expand, due to climate change like when ice melts it makes the water expand. As the water
gets more and more big, then it started slowly moving inwards to the northern region of the United
States then the water overpowers the land. The water breaks down the land very slowly as the years
go by. Over time the land would break down and that would make what is soon to be The Great
Lakes. But this theory is incorrect because if it had been formed by water then the water would follow
cracks that were found on an island In Lake Erie. The water would have taken advantage to the cracks
because the water would have just flowed were all the cracks are. The fractures in the rock would
have indicated were the water would flow, because of this we know water could not have done it
because if the water were to follow the cracks then it would be The Great River not The Great Lakes.
The reason The Great Lakes were created by glaciers was because these giant ice glaciers
