Unit 1: United States and Canada Geography

The North American landscape has played a big role in how the United States and Canada grew. The United States and Canada share many landforms including the Rocky Mountains, the Great Plains, and the Great Lakes. The Mississippi River is the largest river system in North America. Natural harbors and navigable rivers in North America have helped make trade an important part of the economy.

The United States and Canada also have vast natural resources. Minerals and energy resources have helped create thriving industries. However, not all natural resources will last forever. Oil and natural gas reserves are likely to run out. But even renewable resources can become scarce. Many people are working to improve the scarcity of fish and trees.

Most people in the United States and Canada live in a temperate climate zone. In certain areas tornadoes, hurricanes, and blizzards can devastate parts of the region. In other areas, earthquakes and volcanoes can destroy entire towns and cities. Some scientists believe global warming can also cause extreme weather conditions.
