I am suppose to create a power-point presentation on ONE of the following Canadian Landforms:Canadian Shield, Appalachians, Western Cordillera, Arctic Islands, Interior Plains, Great Lakes-St.Lawrence lowlands. My question is which one should I pick?

Question

Which one has the most information I can find on the internent?

I would need to include Geological History, Rock Structure, Appearance, soil, vegetation, wildlife, and human activities.

Please help. Thanks in advance.

I Googled Canadian Shield and found this page with at least 8 links to sites that look useful.
