Physical Geography of North America

North America is a continent in the Earth’s northern hemisphere and almost fully in the western hemisphere. It is bordered on the north by the Arctic Ocean, on the east by the North Atlantic Ocean, on the southeast by the Caribbean Sea, and on the south and west by the North Pacific Ocean; South America lies to the southeast, connected to North America by the Isthmus of Panama. It is the third-largest continent in area, after Asia and Africa, and is fourth in population after Asia, Africa, and Europe.

Physical Geography of North America

North America is the third largest continent, and is also a portion of the second largest supercontinent if North and South America are combined into the Americas and Africa, Europe, and Asia are considered to be part of one supercontinent called Afro-Eurasia.

With an estimated population of 580 million and an area of 24,709,000 sq km, the northernmost of the two continents of the Western Hemisphere is bounded by the Pacific Ocean on the west; the Atlantic Ocean on the east; the Caribbean Sea, Atlantic and Pacific oceans, and South America on the south and the Arctic Ocean on the north.


The northern half of North America is sparsely populated and covered mostly by Canada, except for the northeastern portion, which is occupied by Greenland, and the northwestern portion, which is occupied by Alaska, the largest state of the United States. The central and southern portions of the continent are occupied by the contiguous United States, Mexico, and numerous smaller states in Central America and in the Caribbean.

Natural features of North America include the northern portion of the American Cordillera, represented by the geologically new Rocky Mountains in the west; and the considerably older Appalachian Mountains to the east. The north hosts an abundance of glacial lakes formed during the last glacial period, including the Great Lakes. North America’s major continental divide is the Great Divide, which runs north and south down through Rocky Mountains. The major watersheds all drain to the east: The Mississippi/Missouri and Rio Grande into the Gulf of Mexico, and St. Lawrence into the Atlantic.

North America occupies the northern portion of the landmass generally referred to as the New World, the Western Hemisphere, or simply the Americas. Mainland North America is shaped roughly like a triangle, with its base in the north and its apex in the south; associated with the continent is Greenland, the largest island in the world, and such offshore groups as the Arctic Archipelago, the West Indies, Haida Gwaii (formerly the Queen Charlotte Islands), and the Aleutian Islands.

North America is bounded on the north by the Arctic Ocean, on the east by the North Atlantic Ocean, on the south by the Caribbean Sea, and on the west by the North Pacific Ocean. To the northeast Greenland is separated from Iceland by the Denmark Strait, and to the northwest Alaska is separated from the Asian mainland by the much narrower Bering Strait. North America’s only land connection is to South America at the narrow Isthmus of Panama. Denali (Mount McKinley) in Alaska, rising 6,190 metres above sea level, is the continent’s highest point, and Death Valley in California, at Approx 86 metres below sea level, is its lowest. North America’s coastline of Approx 60,000 km—the second longest of the continents after Asia—is notable for the great number of indentations, particularly in the northern half.

The name America is derived from that of the Italian merchant and navigator Amerigo Vespucci, one of the earliest European explorers to visit the New World. Although at first the term America was applied only to the southern half of the continent, the designation soon was applied to the entire landmass. Those portions that widened out north of the Isthmus of Panama became known as North America, and those that broadened to the south became known as South America. According to some authorities, North America begins not at the Isthmus of Panama but at the narrows of Tehuantepec, with the intervening region called Central America. Under such a definition, part of Mexico must be included in Central America, although that country lies mainly in North America proper. To overcome this anomaly, the whole of Mexico, together with Central and South American countries, also may be grouped under the name Latin America, with the United States and Canada being referred to as Anglo-America. This cultural division is a very real one, yet Mexico and Central America (including the Caribbean) are bound to the rest of North America by strong ties of physical geography. Greenland also is culturally divided from, but physically close to, North America. Some geographers characterize the area roughly from the southern border of the United States to the northern border of Colombia as Middle America, which differs from Central America because it includes Mexico. Some definitions of Middle America also include the West Indies.

North America contains some of the oldest rocks on Earth. Its geologic structure is built around a stable platform of Precambrian rock called the Canadian (Laurentian) Shield. To the southeast of the shield rose the ancient Appalachian Mountains; and to the west rose the younger and considerably taller Cordilleras, which occupy nearly one-third of the continent’s land area. In between these two mountain belts are the generally flat regions of the Great Plains in the west and the Central Lowlands in the east.

Canadian Shield_Physical Geography of North America

North America’s first inhabitants are believed to have been ancient Asiatic peoples who migrated from Siberia to North America sometime during the last glacial advance, known as the Wisconsin Glacial Stage, the most recent major division of the Pleistocene Epoch (about 2.6 million to 11,700 years ago). The descendants of these peoples, the various Native American and Eskimo (Inuit) groups, largely have been supplanted by peoples from the Old World. People of European ancestry constitute the largest group, followed by those of African and of Asian ancestry; in addition there is a large group of Latin Americans, who are of mixed European and Native American ancestry.

Geologic history

Continents have collided and broken apart repeatedly over geologic time. When they separate, new ocean basins develop between the diverging pieces through the process of seafloor spreading. Spreading, which originates at oceanic ridges, is compensated (to conserve surface area on the planet) by subduction—the process whereby the seafloor flexes and sinks along inclined trajectories into the Earth’s interior—at deep-sea trenches and the closure of ocean basins by subduction of the seafloor results in continental collisions.

The material moved laterally from spreading ridges to subduction zones includes plates of rock up to 100 km thick. This rigid outer shell of the Earth is called the lithosphere, as distinct from the underlying hotter and more fluid asthenosphere. The portions of lithosphere plates descending into the asthenosphere at subduction zones are called slabs. The many lithosphere plates that make up the present surface of the Earth are bounded by an interlinking system of oceanic ridges, subduction zones, and laterally moving fractures known as transform faults. Over geologic time the system of plate boundaries has continually evolved as new plates have formed, expanded, contracted, and disappeared.

The continent is richly endowed with natural resources, including great mineral wealth, vast forests, immense quantities of fresh water, and some of the world’s most fertile soils. These have allowed North America to become one of the most economically developed regions in the world, and its inhabitants enjoy a high standard of living. North America has the highest average income per person of any continent and an average food intake per person that is significantly greater than that of other continents. Although it is home to less than 10 percent of the world’s population, its per capita consumption of energy is almost four times as great as the world average.


North and South America are widely accepted as having been named after Amerigo Vespucci by the German cartographer Martin Waldseemuller. Vespucci was the first European to suggest that the Americas were not the East Indies, but a new world, previously undiscovered by Europeans.

The second and less generally accepted theory is that the continents are named after an English merchant named Richard Amerike from Bristol, who is believed to have financed John Cabot’s voyage of discovery from England to Newfoundland in 1497. A minutely explored belief that has been advanced is that America was named for a Spanish sailor bearing the ancient Visigothic name of ‘Amairick’. Another is that the name is rooted in an American Indian language.

Geography and extent

North America occupies the northern portion of the landmass generally referred to as the New World, the Western hemisphere, the Americas, or simply America. North America’s only land connection is to South America at the narrow Isthmus of Panama. Geopolitically, all of Panama—including the segment east of the Panama Canal in the isthmus—is often considered a part of North America alone. According to some authorities, North America begins not at the Isthmus of Panama but at the Isthmus of Tehuantepec, Mexico with the intervening region called Central America or Middle America if the Caribbean is included and resting on the Caribbean Plate. Before the Central American isthmus was raised, the region had been underwater. The islands of the West Indies delineate a submerged former land bridge, which had connected North America and South America via Florida.

The continental coastline is long and irregular. The Gulf of Mexico is the largest body of water indenting the continent, followed by Hudson Bay. Others include the Gulf of Saint Lawrence and the Gulf of California.

There are numerous islands off the continent’s coasts: principally, the Arctic Archipelago, the Greater and Lesser Antilles, the Alexander Archipelago, and the Aleutian Islands. Greenland, a Danish self-governing island and the world’s largest, is on the same tectonic plate (the North American Plate) but is not considered to be part of the continent. Bermuda is not part of the Americas, but is an oceanic island formed on the fissure of the Mid-Atlantic Ridge. The nearest landmass to it is Cape Hatteras, North Carolina, and it is often thought of as part of North America, especially given its historical political and cultural ties to Virginia and other parts of the continent.

Physical geography

The vast majority of North America is on the North American Plate. Parts of California and western Mexico form the partial edge of the Pacific Plate, with the two plates meeting along the San Andreas fault.

The continent can be divided into four great regions (each of which contains many sub-regions): the Great Plains stretching from the Gulf of Mexico to the Canadian Arctic; the geologically young, mountainous west, including the Rocky Mountains, the Great Basin, California and Alaska; the raised but relatively flat plateau of the Canadian Shield in the northeast; and the varied eastern region, which includes the Appalachian Mountains, the coastal plain along the Atlantic seaboard, and the Florida peninsula. Mexico, with its long plateaus and cordilleras, falls largely in the western region, although the eastern coastal plain does extend south along the Gulf.

The western mountains are split in the middle, into the main range of the Rockies and the Coast Ranges in California, Oregon, Washington, and British Columbia with the Great Basin – a lower area containing smaller ranges and low-lying deserts – in between. The highest peak is Denali in Alaska.

Countries and territories

North America is often divided into sub regions but no universally accepted divisions exist. “Central America” comprises the southern portion of the continent, but its northern terminus varies between sources. The United Nations includes Mexico in Central America, while most other definitions of the region do not (e.g., the European Union excludes Belize and Mexico from the area). The term Middle America is sometimes used to refer to Mexico, Central America, and the Caribbean collectively.

Northern America is used to refer to the northern countries and territories of North America: Canada, the United States, Greenland, Bermuda, and St. Pierre and Miquelon.

The Caribbean is used to refer to the islands in the Gulf of Mexico and the Caribbean Sea.

River systems of North America

Missouri River

The continent’s longest river is the Missouri which runs from its source to its mouth for 3,767 kilometers. It emerges from the Rocky Mountains in the state of Montana.
