Cordillera of North America
Cordillera of North America, part of the Cordillera mountain system, occupying the western edge of North America (including Central America) and extending more than 9 thousand km from the Beaufort Sea (69° N) to the Isthmus of Panama (9° N). The width of the mountain belt in the state of Alaska reaches 1200 km, in Canada – 1000 km, in the United States – about 1600 km, in Mexico – 1000 km, in Central America – 300 km.
Appalachians
The Appalachians are mountains in the east of North America, in the United States and Canada. They stretch from the southwest (Alabama, USA) to the northeast to Newfoundland (Canada) for almost 3,200 km, including the islands of Saint Pierre and Miquelon (an overseas community of France). The width is from 160 to 480 km. The name is associated with the Appalachian tribe that once lived here. For a long time, the mountains were called “Allegheny”, only since the end of the 19th century the name “Appalachians” has been assigned to them. Now it is used not only for the mountains, but also for the adjacent territories – the so-called Appalachian region.
