Located on the North American continent, the United States of America comprises 48 adjoining states which are bordered to the north by Canada and to the south by Mexico. The 49th state of the USA is Alaska, a huge wilderness territory which lies to the northwest of Canada. Taken as a whole, the continental USA has a land area of approximately 9 and a half million square kilometres (3 and a half million square miles). The 50th state of the USA, Hawaii, lies 4000 kilometres (2500 miles) off the country's western coast, in the middle of the Pacific. Across the length and breadth of this huge country, there is every type of landscape imaginable, from snowy wastes to burning desert and from ocean beaches to rugged mountain peaks. The biggest mountain range in the USA is the Rockies, which forms the continental divide, extending 4800 kilometres (3000 miles) from northern Mexico, through the USA and Canada into Alaska. Further west, close to the Pacific Ocean and on the border between California and Nevada, the Sierra Nevada is the second most important mountain group in the USA.

Spanish is the second most common language in the country, and is spoken by over 12% of the population. The United States holds the world's fifth largest Spanish-speaking population, outnumbered only by Mexico, Spain, Argentina, and Colombia.
