The exposed portion of the
continental crust underlying North America refers to Canadian Shield. The continental
crust is known as the North American Craton which consists of rocks from the
Archean dn Proterozoic eons and extends from Mexico to Greenland. Canadian
Shield also produces great resources that helped most humans for their economic
development. Because of the resources present in the Shield, it has a great
disadvantage to settlers. The primary obstacle to population growth in the area
is the presence of the bare rock, thin soils, muskeg and insects.

Definition of erosion (according to National Geographic): “Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water.”
1. Describe the features that water erosion produces in your images (mountains, canyons, deserts, etc?) What do they have in COMMON?
Mountains: Water erosion would create a waterway around the mountains.
Canyons: Water erosion would create more area between the canyons.
Deserts: Water erosion would generally change the desert’s landscape by making the hills more downslope.
What they have in common: They all create changes to the landscape of different areas.
2. You can see water erosion even when you do not see water. How is this possible? Be clear!
This is possible by rain?
