Where are the Appalachian Mountains, the Rocky Mountains, and the Great Plains in North America?
The Appalachian range is mostly located in the United States but extends into southeastern Canada, forming a zone from 100 to 300 miles wide, running from the island of Newfoundland 1,500 miles south-westward to central Alabama in the United States with foothills in northeastern Mississippi. The Rocky Mountains or Rockies are a major mountain range in western North America. The Rocky Mountains stretch more than 2,980 miles from the northernmost part of British Columbia, in Canada, to New Mexico. The Rocky Mountains are commonly defined as stretching from the Liard River in British Columbia south to the Rio Grande in New Mexico. The Great Plains are the broad expanse of prairie and steppe which lie west of the Mississippi River and east of the Rocky Mountains in the United States and Canada. This area covers parts of the U.S. states of Colorado, Kansas, Montana, Nebraska, New Mexico, North Dakota, Oklahoma, South Dakota, Texas and Wyoming, and the Canadian provinces of Alberta, Manitoba
