The valleys of peace, Athabasca and Hay rivers are the best features in the lowlands. Glacial lake deposits and till plains are mostly peat-covered and are widely spread in the lowlands. The interior plains continue north toward the Arctic Ocean. Most of the drainage, happens northward along The Mackenzie river valley.
Similarly, what are some physical features in the interior plains?
Topography
- The Interior Plains are a vast, large area of plain.
- Most parts consist of gently rolling hills, and deep river valleys.
- In the USA, the Interior Plains run between the Appalachians at the east, and the Rocky Mountains back west.
- In Canada, the Plains lie between the Canadian Shield and the Rockies.
Also know, how were the interior plains formed?
Interior Plains. The Interior Plains were formed when soils near rivers and lakes from the Canadian Shield were deposited and Sedimentary rock were formed horizontally from these deposits, resulting in large areas of flat land, river valleys, and rolling hills.
In Canada, the Interior Plains are involved in only the Prairie provinces. They contain three different elevations, which are separated by escarpments. An escarpment is a steep cliff formed by erosion or faulting. The Interior Plains are generally sloping from east to west, and have gently rolling hills.
