Vegetation:

Cordillera:
Coast and interior forests
Grassland
Parkland
Coniferous forests
Tundra
Open woodland

Coast and Interior Forest: This is primarily a coniferous forest region. The coast region trees show more growth because of a wet climate.

Quaal River Estuary, BC

Interior Plains:
Coniferous forests
Parkland
Grassland
Mixed forest
Tundra

Grassland: This region has short grasses and their is not enough moisture for trees.  The soil in this region is far more fertile than in the forest regions.

Canadian Shield:
Tundra
Coniferous forests
Mixed forest
Open woodland
Subarctic

Open Woodland:  This photo shows the scattered evergreen trees, shrubs, and grass of this region.

Thaydene Nene National Park, Northwest Territories

St. Lawrence Lowlands:
Mixed forest
Coniferous forests

Mixed Forest: This region has softwood trees, such as hemlock and cedar, as well as hardwood trees such as maple, birch, oak, and ash.  The soil is more fertile in this region.

Along the coast of St. Lawrence, Québec.

Appalachian Region:
Coniferous forests
Open woodland
Tundra

Tundra: Treeless landscape with mostly small shrubs, moss, and lichen.

Baffin Island, Nunavut

Arctic Region:
Subarctic
Tundra
Open woodland

Subarctic:  Swampy in areas with tundra vegetation. Some parts of the subarctic also have scattered coniferous trees.

Ogilvie Mountains, Yukon

Formation:

Cordilerra:
Techtonic plates were pushed against eachother and created fold mountains, faulting and volcanic activity. The rocky mountains are made up of sedimentary rock, which creates the folding.

Interior plains:
Covered by shallow interior seas, with sediments coming from the canadian shield and the rockies deposited at the bottom. The weight compressed it to become sedimentary rocks.

Canadian Shield:
Large area of exposed igneous and metamorphic rocks that were formed in below and weathering brought them to the surface. Covered by a thin layer of dirt.

St. Lawrence lowlands:
A glacier scraped all the dirt above to the south. It looks bowl shaped. The earth was pushed down under the weight of the glacier.

Appalacian Region:
A combination of uplands and lowlands, show the complexity of rocks. These were created by tectonic movements.

Arctic Region:
islands of this region are mostly composed of sedimentary rock. This rock is formed from pre-existing rocks eroding into fine small fragments. These fine sediments are compacted together.  Wind and water erosion deteriorates the rock into life-like shapes.
