The Interior Plains stretch across the barren interior of Canada and contain unique physical and geological features. Within the Interior Plains are three levels of elevation. These areas are all categorized as plains and plateaus, and the surface level of the Plains gradually decreases toward the east.
The landscape of the Plains is dotted with hills, cliffs, wide river valleys, vast stretches of deciduous and coniferous forests, low-lying mountains, streams and even sand dunes and sand deposits. The Interior Plains contain rich and fertile soils, which support the growth of crops such as wheat, flax, canola, mustard, sugar beets, corn and potatoes. The region is also rich in fuel products such as zinc, oil, natural gas and coal, while forests provide habitat for wildlife and lumber.
