Major Relief Features (Landforms) of Continental Areas

The brown area shows the part of the North American continent that has been stable for over 600 million years. This region is made up of a basement older Precambrian metamorphic and igneous rock that is mostly covered by a relatively thin cover of younger sedimentary rock. Geologists call these long-stable continental cores cratons.

The Canadian or Laurentian Shield (Craton)

Old Fold Mountains

Atlantic Coastal Plain
