2North America (Total Area) Canada and the United States rank as two of the largest countries in the world area wise.1. Russia2. Canada3. United States4. China5. Brazil
3Natural ResourcesBoth Canada and the United States are global economic powers because they have a ton of natural resources.Examples include: coal, copper, iron ore,petroleum, timber, natural gas, lead etc.
4Oceans and WaterwaysEight of the world’s largest lakes are on the North American Continent. *The Great Lakes are 5 of them.Huron, Ontario, Michigan, Erie and Superior.The Mississippi River goes most of the length of the United States from North to South.
5Canada’s longest river is the Mackenzie River, which empties out into the Arctic Ocean.
6Land and ForestsNorth America is the world’s number one food exporter. This is because the United States and Canada have some of the most fertile soils in the world.½ of Canada is covered by woodlands1/3 of the U.S. is covered by forestsAlthough Canada has more timber, the U.S. has a higher variety of trees.
7Energy ResourcesThe U.S. consumes more energy resources than any other country in the world. Canada supplies the U.S. with a lot of energy resources.

9Chapter 5 Section 2Alaska & Canada have tundra climate and vegetation.Winters= Long & ColdSummers= Short & Chilly (Even in July the temperature is 40 degrees F.)
10Rocky Mts. & Pacific ranges tend to have a cold climate with sparse vegetation. North central & northeastern part of the U.S. and southern Canada have a humid continental climate.Winters= ColdSummers= Warm

18Settlement and Agriculture of North America The first inhabitants of North America came from Asia.Food sources of early settler’s included wild game and plant foods. (Hunters & Gatherers)Early farmers cut down trees for lumber to build houses and to burn as fuel.
19The first Americans lived along coastlines and near rivers and streams because water was, and still is necessary for survival.Landscape, climate, weather and the availability of natural resources also played a role as to where people settled.
20Obstacles that early settlers faced when coming to North America included: huge distances, large bodies of water, harsh climates and hazardous landforms.
21Present Canada and U.S.Agriculture is still an important economic activity in the United States and Canada. Both countries are leading exporters of agricultural products.The United States has the world’s largest railroad system, while Canada has the third largest.The U.S. has nearly 4 million miles of roads, and Canada has about 560,000 miles of roadways.
