What does the Canadian Shield look like?
The physical features of the Canadian Shield includes rocks , bares and plateaus . The Canadian Shield has uplands which are high or hilly areas, and there are also a lot of rivers , lakes , streams and wetlands. Wetlands help clean water by trapping harmful chemicals.
What are the characteristics of the Canadian Shield?
The Canadian Shield’s most notable physical features are thousands of small lakes, thin layers of soil and rolling hills. Lakes are largely the result of glacial erosion during the last ice age.
What are 3 fun facts about the Canadian Shield?
It is mainly composed of granite and has a thin layer of soil. A total of four different mountain ranges rise from the Canadian Shield. The Precambrian rocks of this shield are estimated to be around 570 million years old. The Canadian Shield is also known as the Precambrian Shield and the Laurentian Plateau.
How thick is the Canadian Shield?
The sedimentary cover is less than a mile thick on the platform, but it increases to about 2.5 miles (4 km) in the Hudson Bay, Michigan, Williston, and Illinois sedimentary basins and to 4 miles (6 km) and more in troughs adjacent to the peripheral orogenic belts.
How did the Canadian Shield differ in appearance from today?
How did the Canadian Shield differ during the Precambrian era in appearance from today? It used to be mountains, now it’s levelled by erosion, leaving rock covered by soil and many lakes.
What are the characteristics of the interior lowlands?
The Interior Lowlands are located west of the Appalachian Mountains and east of the Great Plains. There are rolling flatlands with many rivers, broad river valleys, and grassy hills.
What are the 3 main economic sectors in the Canadian Shield?
Natural Resources / Industries in the Canadian Shield Region today: 1) Furs – from fur bearing animals (hunting and trapping is still a large industry). 2) Minerals – this makes a lot of sense because the Shield is solid rock. Canadians extract copper, gold, nickel , zinc and lead from this area.
What is Canadian Shield explained to kids?
The Canadian Shield is a broad region of Precambrian rock (pictured in shades of red) that encircles Hudson Bay. It spans eastern, northeastern, and east-central Canada and the upper midwestern United States. The Canadian Shield is also called the Laurentian Plateau, or Bouclier canadien (French).

Why is it called Canadian Shield?
The Canadian shield gets its name from its shape, which resembles an ancient shield, raised and ready to defend North America. The Canadian shield’s bare surface makes it much more useful for mining, logging, hydroelectric power generation, and similar operations that do not require deep earth.
What is the Canadian Shield and why is it special?
The Canadian Shield constitutes the largest mass of exposed Precambrian rock on the face of Earth. The region, as a whole, is composed of ancient crystalline rocks whose complex structure attests to a long history of uplift and depression, mountain building (orogeny), and erosion.
Why is the Canadian Shield almost completely uninhabited?
This is the vast, northwestern part of Canada that contains the three territories: Yukon, Nunavut and the Northwest Territories. This region has dry, barren, and mostly uninhabited areas. This is largely because it has long, cold winters with heavy snow and perpetually frozen soil.
How would you describe the Canadian Shield?

What are some facts about the Canadian Shield?
The Canadian Shield is also known as the Precambrian Shield and the Laurentian Plateau. The highest points of this shield are located on Baffin Island and in northern Labrador. This shield is also home to the world’s largest Boreal Forest. This region has a long volcanic history and it is mainly composed of igneous rocks.
What are the geographic features of the Canadian Shield?
Notable physical features in the Canadian Shield include the rolling hills, a shallow layer of soil, and hundreds of small lakes formed during the last glacial erosion. Other features from the glacial period include striations and drumlins.
Why is the Canadian Shield important?
In addition to its rich natural resources, including substantial deposits of such mineral ores as nickel, gold, silver, and copper, and pristine northern ecosystems, the Canadian Shield also serves as a fertile area for human beings trying to better understand the origin of life.
