According to the text,what is the origin of the large depressions in the Northern
Moraine and Lake Region some of which contain lakes?
They were formed by tectonic activity, creating deep basins that filled with
water.
They were formed when large blocks of glacial ice were buried beneath
outwash sediments, later melting to form kettle holes or kettle lakes.
They were formed by stream erosion, carving out deep valleys that
subsequently filled with water.
They were formed by the accumulation of moraines.which blocked natural
drainage and created lakes.
