Where is the U.S. located on the map?

The United States is a country in North America, including Alaska (in northwestern Canada) and the Hawaiian Islands (in the North Pacific).

The United States of America 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. As a federal republic of fifty states and a federal district, with a few islands in the Pacific (Midway, Wake), the United States also has a trusteeship over certain islands and archipelagos of the Pacific and the Caribbean, with status 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) ).

With an area of 9,826,630 km², including 1,717,854 km² in Alaska, the United States is a “continental state”, the fourth largest in the world, with two ocean frontages. The United States stretches 4,517 km from east to west and 2,572 km from north to south. They present, because of the extent of their territory, a great variety of climates and landscapes. The highest point of the country is in Alaska, at the summit of Mount McKinley (6,194 m). The lowest point is in Death Valley, California, 86 m below sea level.

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 American states are divided into counties, with the exception of Louisiana, divided into parishes.

Detailed map of USA … Where exactly is the United States located?

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 to the west, large, trans-boundary conurbations (Portland-Seattle-Vancouver, northwest, Los Angeles-San Diego-Tijuana, southwest).

The physical frame of the country is very simple, 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.

The western United States is occupied by the long North American cordillera. Known as the Rocky Mountains, it forms a complex orogenic system, with a maximum width of 1,500 km between Denver and San Francisco. It is divided into three groups: Pacific Ranges in the west, high desert plateaus in the center, and an imposing mountain barrier in the east. The latter rises to 4 399 m at the summit of Mount Elbert. The main chains are the Bitterroot Range and the Salmon River Mountains in the north, the Front Range and the San Juan Mountains in the center and the Sangre de Cristo Mountains in the south.

The Great Inland Plains, the central part of the North American continent, is a large sedimentary basin drained by the Missouri-Mississippi River system. Below the Rocky Mountains lie the “High Plains”, high plateaus of Piedmont (Llano Estacado) culminating at nearly 2,000 m altitude, deeply cut by tributaries of the right bank of Mississippi (Missouri, Arkansas). They are connected, by a glacis gently inclined towards the east, to the central lowlands (Central Lowland). To the south, on the other hand, they dominate the coastal plain of the Gulf of Mexico by an escarpment (Balcones Escarpment).

To the east rises the Appalachian Mountains, a medium mountain at 2,037 m, at Mount Mitchell. Stretched over 2,000 km from the Canadian border to Alabama, it reaches a width of nearly 500 km at the height of Pennsylvania.

Old primary massif, eroded in the secondary era, raised and rejuvenated in the Tertiary, then dug by the Quaternary glaciers, the Appalachians are formed on the west by limestone plateaus (Cumberland plateau to the south, Allegheny mountains to the north), center by a succession of ridges and parallel furrows (Great Valley), and to the east by the Blue Ridge, which rise between 1500 and 2000 m altitude. A series of cluses allow the transversal crossing. To the north-east, the northern Appalachians (New England) consist of several massifs shaped by the Quaternary glaciers (Adirondack Mountains, Catskill Mountains, Green Mountains), at the origin of a multitude of lakes and a rocky coast notched by fjords (Hudson).

The humid continental climate of the North-East (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 activity in 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.

The dry climate of the Central Great Plains is affected by the effects of continentality: the brutality of seasonal thermal contrasts is accompanied by a gradual decrease in precipitation from east to west. Irrigation becomes essential west of the 100th meridian, where increasing drought is associated with seasonal erratic rains. The “High Plains” plateau sometimes experiences very violent winds (blizzards) and tornadoes, affecting in particular the states of Oklahoma and Kansas, where they are responsible for a significant wind erosion of soils (“Dust Bowl”, 1935).

The climate becomes frankly desert in the western interior plateaus, especially south of the Great Basin (Valley of Death, Mojave Desert), which experience hot summer.

The oceanic climate of the Pacific Northwest is very humid and is characterized by a low annual thermal amplitude (mild winter, cool summer). Rainfall is very abundant on the mountains (Olympic Mountains, Cascade Mountains).

The Mediterranean climate of the Southwest Pacific is different from the previous one by its summer drought. The south of the coast knows the hot and dry wind of Santa Ana, causing serious forest fires. Summer is relatively cool on the shoreline, due to the cold California current, causing thick mists, aggravated by pollution (smog). It gets hotter and warmer inwards. The hinterland is desert and irrigation is necessary.
