Landforms and Natural Resources
 U.S. and Canada are bound together by
both physical geography and
cultural heritage as well as strong
economic and political ties

 Both are rich in natural resources
 Fertile soils, ample supplies of H20, vast forests and large
deposits of a variety of minerals
 Popular with immigrants from around the world
Many and Varied Landforms
Eastern Lowlands
Appalachian Highlands
 Flat, coastal plain along the
 Runs north to south from
narrower Atlantic coast from the
Northeast to Florida
 Offers many excellent harbors

 Rocky Mtns – Massive & rugged
huge glaciers 1000’s of years ago
 Includes lowland, rolling

rivers + some of the most
fertile soil
 Divided into 3 sub-regions:
 Interior Plains – Appalanchains
to 300 miles west of Mississippi
 Great Plains – largely treeless
area up to 4,000 ft.
 Canadian Shield – rocky, mainly

of Mexico
 Great Lakes – Superior,
Michigan, Huron, Erie and
Ontario
 Lands and Forests
 Minerals and Fossil Fuels
 Gives U.S. & Canada means to

 U.S. = world’s biggest consumer
