Cordillera

The landscape is made up of parallel mountain ranges. They were formed when plate collision caused Earth’s crust to buckle, push and fold into mountains.

Interior Plains Region

were formed as soils carried by rivers from the Canadian Shield were deposited at its edge. They then formed layers of sedimentary rock, which became large areas of flat land, rolling hills and river valleys.

  1. Good job. With the Arctic, when you mention fold mountains, try to find a diagram of the formation of them. Not sure if the diagram you have is clear about mountains folding, I think it’s kind of there under the mountain to the right but again, not the clearest.
