The Arctic Region includes many plains, lowlands, and mountains. One of the topography in Arctic Region is fold mountains. These mountains, called the Innuitian Mountains, extend more than 1000 km across the northern islands of the Arctic region. It’s formed by the pressure at the edge of the Canadian Shield pushed up the sedimentary rocks.

The Appalachian Region

The Appalachian Region is an extension of the Appalachian mountains. It includes the landscape of rolling hills, valleys, small mountains, highlands, and coastal fjords.

*Deposits of coal and minerals, rich fishing resources, vast forests, and farmland encouraged the creation of numerous communities along the coast and in the river valleys of the Appalachian region.

The Canadian Shield Region

The Canadian Shields are hard, rigid blocks, surrounded by younger continental landforms. It was once a volcanic mountain range but over a millons of years, weathering and erosion, and especially the action of glaciers have changed the land to a landscape of flat, bare rock, lakes, and wetlands.

Flat, Wetland

Lakes

 The St.Lawrence Lowlands had giant lakes that were formed by melted ice sheets, these drained and the old shoreline became bluffs. In between the bluffs and lakes are flat, rolling valleys that are extremely fertile and make up the rich land around Lake Ontario and the St. Lawrence River.

 The Interior Plains consists of grasslands that are ideal for animals to graze. They are also covered with sedimentary layers that have been deposited over millions of years. Not only does the Interior Plains include flat prairies and farmland but is surrounded by river, and forests. This has formed rich soils and makes this region ideal for farming and raising animals.

 The Cordillera contains a varity of mountains such as the Rockies and Coast Mountains. The erosion of the rivers and glaciers have created these mountainous landscape we see today. Plate tectonics also cause the cordilleras plateaus, valleys and trenches.
