The United States of America, a federal republic in North America, consists of 50 states: Alaska, Hawaii and 48 states in the territory between the Atlantic and Pacific oceans and between Canada and Mexico. The United States is a giant state, a leading economic and military power, and the third largest in the world in terms of area and population.
The main part of the US territory is divided into eight provinces: Appalachians, Coastal Plains, Inland Elevations, Inner Plains, Elevation at Lake Superior, the Rocky Mountains, Intermountain Plateau and Pacific Coastal Mountains. Alaska and the Hawaiian Islands are also separate provinces.
