The Interior Plains Region is located in Canada and the United States. The Interior Plains were formed when cratons collided and welded together. The Interior Plains Region is mostly flat due to more than 500 million years of relative tectonic stability. The only exception to the flatness is the Black Hills of South Dakota. The Interior Plains region in Canada is called Canada's breadbasket. There are more than 4,000,000 people in the interior plains region. Metamorphic and igneous rocks now form the basement of the Interior Plains and make up the stable important elements of North America. The Interior Plains were covered by shallow inland seas. Sediments from the shield and the Rocky Mountains were deposited in these seas over millions of years.
Great plains and The Canadian shield
One major difference between Coastal plains and Interior plains is in elevation. Coastal plains have low elevation and low relief. Interior plains have varied elevation and low relief. Coastal plains also lie along the shore while Interior plains are surrounded by other land.

The Prairies are considered Canada's breadbasket, and are the Canadian section of a much larger North American region called the Interior Plains. The Prairies consist of three provinces: Alberta, Saskatchewan and Manitoba.
