Answer:
Ice age is a period where there is expansion of glaciers and this leads to certain land forms. There were some land forms that were formed during the period of ice age due to the glaciers of that time. Great lakes were the creation of some land forms by the glaciers.
But the land form that was created due to the indirect effect of the glaciers in the ice age was the pluvial lakes. Striations, U shaped valley and cirques also are the land forms created.
