Which region is one of Canada's Lowlands?

• A. Interior plains
• B. Plateaus region
• C. Great Lakes/St. Lawrence Lowlands
• D. Arctic/Hudson Bay Lowlands

Answer: (C)

In Canada, lowlands are flat, low-lying areas shaped by glaciers and major rivers, with gentle relief and soils that are often very fertile. The Great Lakes/St. Lawrence Lowlands fit this description exactly. It sits along the southern edge of Ontario and Quebec, hugging the Great Lakes and the St. Lawrence River. The land here remains at a relatively low elevation and is mostly flat to gently rolling, a result of glacial deposits and sediment that filled the basins after the last Ice Age. This combination of low relief, proximity to large waterways, and rich soils has made it a key agricultural and population center, which is why it’s identified as one of Canada’s Lowlands.

The other regions differ in character: plateaus have higher, rugged terrain; interior plains are broad, interior flatlands but are typically viewed as a separate plain region rather than a Lowland; and while there is also Arctic/Hudson Bay Lowlands, the southern Great Lakes/St. Lawrence Lowlands are the classic example often highlighted in introductory geography for being a Lowland.
