This major mountain range lies west of the Great Plains.

Huge forests help the United States and Canada produce lumber and these products used for books and notebooks.

These people move from place to place rather than living permanently in one settlement.
Nomads
This largely treeless region rises gradually toward the west.
The Great Plains
The Great Lakes connect with this river to form a major shipping route to the Atlantic Ocean.
The St. Lawrence River
The Arctic coast of Alaska and Canada has this climate, associated with a huge, treeless plain.
tundra
Coal, oil, and natural gas belong to this category of energy resources.
Fossil fuels
The spread of a city into surrounding valleys, foothills, and other nearby areas is called this.
urban sprawl
This area of rolling hills lies between the eastern coastal plains and the Appalachian Highlands.
The Piedmont
This imaginary boundary separates rivers flowing toward opposite sides of the continent.
The Continental Divide
Central and southern coastal California have this climate, characterized by dry, sunny, warm summers.
Mediterranean
Farmers use this method to bring water to dry agricultural land.
Irrigation
Montreal developed large connected underground areas to help people cope with this challenge.
Severe winters / extreme cold
This mainly flat region surrounds Hudson Bay.
The Canadian Shield
Name two ways rivers and lakes support people besides providing drinking water.
Any two: transportation/shipping, hydroelectric power, irrigation, or fishing
Warm Gulf air and cold Canadian air can meet over the Great Plains. Name two types of severe weather this can produce.
Any two: thunderstorms, tornadoes, or blizzards
Name two geographic features or resources that make the interior plains and river valleys useful for agriculture.
Any two: fertile soil, relatively flat land, or available river water
Name two problems associated with Los Angeles’s growth discussed in the chapter.
Any two: air pollution, inadequate water supplies, or construction on earthquake-threatened land

Explain two ways a large forest can support a region’s economy.
Examples: supplying lumber, supplying materials for paper, and providing jobs in forestry, manufacturing, or transportation
Explain how Montreal’s underground development and farmers’ irrigation systems each help people respond to their environment
Montreal’s underground spaces help people avoid severe winter weather; irrigation brings water to places too dry for reliable farming.
