The United States is a country in the Western Hemisphere. Most of the country is in the central part of North America. It is boarded by Canada on the north and Mexico on the south. Due to its geographical position 48 states are conterminous, or enclosed within one common boundary. The other 2states, Hawaii (in the Pacific Ocean) and Alaska (in the far northwestern part of North America), are located apart from the rest of the country. The physical geography of the US is varied. There are huge forests, large areas of flat, grassy plains and deserts. Within the continental U.S., eight distinct physiographic divisions exist, though each is composed of several smaller physiographic subdivisions.
