The Ozark Plateau and Ouachita Mountains form the area collectively known as the US Interior Highlands.
The Great Plains are a result of the receding seaway paving the way to the relatively flat terrain during Late Cretaceous to the Paleocene (65-55 million years ago).
The Great Lakes were formed during the last glacial period (around 14,000 years ago), in the late-Pleistocene period.
The Black Hills formation ranges from the Precambrian through Paleozoic - Mesozoic until Cenozoic.
