Interior Plains
Description
• Flat to rolling plains
• 3 levels separated by
escarpments
• Deep river valleys
Rock Type

Southern Manitoba
Interior Plains
Human Activities
• Agriculture (wheat)
• Oil and gas

• Cattle ranching
Canadian Shield
Description
• Oldest rock
• Relatively flat with
rounded hills
• Thousands of lakes
• Saucer shaped
Rock type
• Igneous and
Metamorphic
A boulder in the Northwest
Territories.
It was deposited here by a
retreating glacier.
Canadian Shield
Formation
• Volcanic mountains
(igneous rock)
• Erosion leveled
mountains
• Glaciers scraped soil and
made lakes.
Notice the scratches in the
rock. They were caused by
Glaciers retreating.
