| OFFICIAL NAME:
United States of America COUNTRY DESCRIPTION The United States is a stable, highly developed constitution-based
federal republic with a strong democratic tradition and a
modern economy. Tourist facilities are widely available.GEOGRAPHY The United States is located in North America, bordering both the North Atlantic Ocean and the North Pacific Ocean, between Canada and Mexico. The world's third-largest country by size (after Russia and Canada)
and by population (after China and India), about half the size of
Russia; about three-tenths the size of Africa; about half the size
of South America (or slightly larger than Brazil); slightly larger
than China; more than twice the size of the European Union. Mt.
McKinley is highest point in North America and Death Valley the
lowest point on the continent.There is a vast central plain, mountains in the west, hills and low mountains in the east, rugged mountains and broad river valleys in Alaska, and rugged, volcanic topography in Hawaii. The climate is mostly temperate, but tropical in Hawaii and Florida, arctic in Alaska, semiarid in the great plains west of the Mississippi River, and arid in the Great Basin of the southwest. Low winter temperatures in the northwest are ameliorated occasionally in January and February by warm chinook winds from the eastern slopes of the Rocky Mountains. Natural hazards include tsunamis, volcanoes, and earthquake activity around the Pacific Basin; hurricanes along the Atlantic and Gulf of Mexico coasts; tornadoes in the midwest and southeast; mud slides in California; forest fires in the west; flooding; permafrost in northern Alaska is a major impediment to development. Current environmental issues include air pollution resulting in acid rain in both the US and Canada; the US is the largest single emitter of carbon dioxide from the burning of fossil fuels; water pollution from runoff of pesticides and fertilizers; limited natural fresh water resources in much of the western part of the country require careful management; desertification. BACKGROUND Britain's American colonies broke with the mother country in 1776 and were recognized as the new nation of the United States of America following the Treaty of Paris in 1783. During the 19th and 20th centuries, 37 new states were added to the original 13 as the nation expanded across the North American continent and acquired a number of overseas possessions. The two most traumatic experiences in the nation's history were the Civil War (1861-65) and the Great Depression of the 1930s. Buoyed by victories in World Wars I and II and the end of the Cold War in 1991, the US remains the world's most powerful nation state. The economy is marked by steady growth, low unemployment and inflation, and rapid advances in technology.
