The continental United States stretches from the Atlantic Ocean to the Pacific Ocean and from Canada to Mexico and the Gulf of Mexico. Separated by Canada, it touches the Pacific and Arctic Oceans. Hawaii occupies an archipelago in the Pacific, southwest of North America. The commonwealth of Puerto Rico, the largest and most populous U.S. territory, is in the northeastern Caribbean. Deciduous vegetation and grasslands prevail in the eastern U.S., transitioning to prairies, boreal forests, and the Rocky Mountains in the west, and deserts in the southwest. In the northeast, the coasts of the Great Lakes and Atlantic seaboard host much of the country's population. With a few exceptions such as the territory of Guam and the westernmost portions of Alaska, nearly all of the country lies in the western hemisphere.

Beyond the coastal plain, the rolling hills of the Piedmont end at the Appalachian Mountains. The Rocky Mountains, at the western edge of the Great Plains, extend north to south across the continental U.S., reaching altitudes higher than 14,000 feet (4,270 m) in Colorado. Between the Appalachian and Rocky Mountains, the Interior Plains and Great Plains are relatively flat, fertile farm land. The Mississippi-Missouri River, the world's fourth longest river system, runs mainly north-south through the heart of the country. Active volcanoes are common throughout the Alexander and Aleutian Islands and the entire state of Hawaii is built upon tropical volcanic islands. The supervolcano underlying Yellowstone National Park in the Rockies is the continent's largest volcanic feature.
