Write a paragraph describing the formation of the great lakes, using the terms glaciation and gravity.
If someone could just explain the process in a more simple manner that would help me a lot. Thank you.

The Great Lakes are a large group of freshwater lakes that straddle the border between the United States and Canada. They were formed as the result of glacial abrasion during the last ice age, which occured about ten thousand years ago. Huge sheets of glacial ice reached as far south as mid-America, and carved out divots and depressions in the Earth's crust as a result of their slow, deliberate movement. The glaciers acted like huge bulldozers, with the force of gravity pulling down on the mass of all that ice, piling up elevations of debris referred to as moraines. When the ice age ended, the glaciers melted, leaving behind large deposits of fresh water to fill the Great Lakes. Glacial ice can still be found today in extreme northerly and southerly latitudes, around the north and south poles.
