3) BORDERS:









The United States is bordered on the north by Canada, on the east by the Atlantic Ocean, on the south by the Gulf of Mexico and Mexico, and on the west by the Pacific Ocean. The United States is a federal republic formed by fifty states and a federal district, with a few islands in the Pacific (Midway, Wake), and is also a trustee of some Pacific and Caribbean islands and archipelagos Associated State (Puerto Rico), "Freely Associated" Territories (Marshall Islands, Federated States of Micronesia and Belau) or "Unincorporated" Territories in the United States (American Samoa, Guam, Virgin Islands).









4) TOTAL AREA:









With an area of ​​9,826,630 km^2, including 1,717,854 km² in Alaska, the United States is a "continental state", the fourth largest in the world, with two ocean facades. The United States of America contain 4,518 km from east to west and 2,572 km from north to south. They have a large variety of climates and landscapes due to the size of their territory. The highest point of the country lies in Alaska, at the summit of Mount McKinley (6,194 m). The lowest point is about 86 m below sea level in Death Valley, California.









5) THE ALL STATES:









The United States is a federal republic consisting of 50 states and one federal district (District of Columbia), including the federal capital, Washington: Alabama, Alaska, Arizona, Arkansas, California, North Carolina, South Carolina, Colorado , Connecticut, North Dakota, South Dakota, Delaware, Florida, Georgia, Hawaii, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska Nevada, New Hampshire, New Jersey, New York, New Mexico, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, Tennessee, Texas, Utah, Vermont, Virginia, West Virginia, Washington, Wisconsin, Wyoming. Almost all US states are divided into counties, with the exception of Louisiana, divided into parishes









6) THE MAIN CITIES:









The country has 39 metropolises with more than 1 million inhabitants, these 39 metropolitan areas include 124.8 million people, or half of the total population. The ten largest cities, in 1990, were New York (18 million), Los Angeles (14.5 million), Chicago (8 million), San Francisco (6.2 million), Philadelphia, (5.9 million), Detroit (4.6 million), Boston (4.1 million), Washington (3.9 million), Dallas (3.8 million), Houston (3.7 million). The Pacific and Atlantic facades are characterized by very strong urban concentrations, with in the east the powerful Megalopolis (45 million inhabitants of Boston in Washington), which records very high densities (396 inhabitants per km ² in New Jersey) and, in the west, large, trans-boundary conurbations (Portland-Seattle-Vancouver, northwest, Los Angeles-San Diego-Tijuana, southwest).









7) RELIEF:









The physical framework of the country is very simple, just like the North American continent (see North America). Three major meridian ensembles follow one another from west to east: the mountainous system of the Rockies, the Central Great Plains (Middle West) and the old Appalachian Massif, bordered by a narrow coastal plain on the Atlantic.









8) CLIMATE:









The dominant feature of the US climate is continentality, characterized by a strong annual thermal amplitude and low rainfall. However, the country presents a great variety of climates, resulting from the combination of different factors: the extension in latitude, the continental scale, the air masses (of polar or tropical origin), the topography (orographic barriers of Appalachians and Rockies, meridian relief organization), or the presence of cold or hot ocean currents.

The humid continental climate of the Northeast (New England, Central-East) is characterized by strong seasonal thermal contrasts. Summers are hot and winters are unusually cold for latitude and given the proximity of the Atlantic (Labrador Current). Precipitation is abundant, especially in winter, when the combination of humidity and cold causes heavy snowfall, which regularly paralyzes the activity of large cities.

The humid subtropical climate of the Southeast is characterized by mild winters and hot, humid summers. The coast is regularly hit by devastating cyclones.
