Study Notes
- North America can be divided into three main physical regions: the Western Cordilleras or mountain ranges, the central plains, and the Eastern Highlands.
- The Western Cordilleras stretch from Alaska to Panama along the western coast and include the Rocky Mountains, the Cascade Range, the Coastal Range, the Sierra Nevada, and the Sierra Madre.
- The Central Plains, also known as the Great Plains, extend from the Arctic Ocean to the Gulf of Mexico and include the Canadian Shield and the vast lowlands drained by the Mississippi River.
- The Canadian Shield, part of the Central Plains, was covered with ice during the Ice Age, resulting in the formation of depressions that later became the Great Lakes.
- The Mississippi River, along with its tributary Missouri, is the third longest river in the world and forms a large Delta before flowing into the Gulf of Mexico.
- The Eastern Highlands consist of the Appalachians, a chain of old fold mountains stretching from the St. Lawrence River valley down through most of the eastern United States.
