Geography - note

This entry includes miscellaneous geographic information of significance not included elsewhere.

Afghanistan

landlocked; the Hindu Kush mountains that run northeast to southwest divide the northern provinces from the rest of the country; the highest peaks are in the northern Vakhan (Wakhan Corridor)

British extraterritorial rights also extended to several small off-post sites scattered across Cyprus; of the Sovereign Base Area (SBA) land, 60% is privately owned and farmed, 20% is owned by the Ministry of Defense, and 20% is SBA Crown land

Albania

strategic location along Strait of Otranto (links Adriatic Sea to Ionian Sea and Mediterranean Sea)

Algeria

largest country in Africa but 80% desert; canyons and caves in the southern Hoggar Mountains and in the barren Tassili n'Ajjer area in the southeast of the country contain numerous examples of prehistoric art - rock paintings and carvings depicting human activities and wild and domestic animals (elephants, giraffes, cattle) - that date to the African Humid Period, roughly 11,000 to 5,000 years ago, when the region was completely vegetated

American Samoa

Pago Pago has one of the best natural deepwater harbors in the South Pacific Ocean, sheltered by shape from rough seas and protected by peripheral mountains from high winds; strategic location in the South Pacific Ocean

Andorra

landlocked; straddles a number of important crossroads in the Pyrenees

Angola

the province of Cabinda is an exclave, separated from the rest of the country by the Democratic Republic of the Congo

Anguilla

the most northerly of the Leeward Islands in the Lesser Antilles

Antarctica

the coldest, windiest, highest (on average), and driest continent; during summer, more solar radiation reaches the surface at the South Pole than is received at the Equator in an equivalent period

mostly uninhabitable, 99% of the land area is covered by the Antarctic ice sheet, the largest single mass of ice on earth covering an area of 14 million sq km (5.4 million sq mi) and containing 26.5 million cu km (6.4 million cu mi) of ice (this is almost 62% of all of the world's fresh water); if all this ice were converted to liquid water, one estimate is that it would be sufficient to raise the height of the world's oceans by 58 m (190 ft)

Antigua and Barbuda

Antigua has a deeply indented shoreline with many natural harbors and beaches; Barbuda has a large western harbor

Arctic Ocean

major chokepoint is the southern Chukchi Sea (northern access to the Pacific Ocean via the Bering Strait); strategic location between North America and Russia; shortest marine link between the extremes of eastern and western Russia; floating research stations operated by the US and Russia; maximum snow cover in March or April about 20 to 50 centimeters over the frozen ocean; snow cover lasts about 10 months

Argentina

note 1: second-largest country in South America (after Brazil); strategic location relative to sea lanes between the South Atlantic and the South Pacific Oceans (Strait of Magellan, Beagle Channel, Drake Passage); diverse geophysical landscapes range from tropical climates in the north to tundra in the far south; Cerro Aconcagua is the Western Hemisphere's tallest mountain, while Laguna del Carbón is the lowest point in the Western Hemisphere; shares Iguazú Falls, the world's largest waterfalls system, with Brazil

note 2: southeast Bolivia and northwest Argentina seem to be the original development site for peanuts

Armenia

landlocked in the Lesser Caucasus Mountains; Sevana Lich (Lake Sevan) is the largest lake in this mountain range

Aruba

a flat, riverless island renowned for its white sand beaches; its tropical climate is moderated by constant trade winds from the Atlantic Ocean; the temperature is almost constant at about 27 degrees Celsius (81 degrees Fahrenheit)

Ashmore and Cartier Islands

Ashmore Reef National Nature Reserve established in August 1983; Cartier Island Marine Reserve established in 2000

Atlantic Ocean

major chokepoints include the Dardanelles, Strait of Gibraltar, access to the Panama and Suez Canals; strategic straits include the Strait of Dover, Straits of Florida, Mona Passage, The Sound (Oresund), and Windward Passage; the Equator divides the Atlantic Ocean into the North Atlantic Ocean and South Atlantic Ocean

note 2: the Great Dividing Range that runs along eastern Australia is that continent’s longest mountain range and the third-longest land-based range in the world; the term "Great Dividing Range" refers to the fact that the mountains form a watershed crest from which all of the rivers of eastern Australia flow – east, west, north, and south

note 3: Australia is the only continent without glaciers; it is the driest inhabited continent on earth, making it particularly vulnerable to the challenges of climate change; the invigorating sea breeze known as the "Fremantle Doctor" affects the city of Perth on the west coast and is one of the most consistent winds in the world; Australia is home to 10% of the world's biodiversity, and a great number of its flora and fauna exist nowhere else in the world

Austria

note 1: landlocked; strategic location at the crossroads of central Europe with many easily traversable Alpine passes and valleys; major river is the Danube; population is concentrated on eastern lowlands because of steep slopes, poor soils, and low temperatures elsewhere

note 2: the world's largest and longest ice cave system at 42 km (26 mi) is the Eisriesenwelt (Ice Giants World) inside the Hochkogel mountain near Werfen, about 40 km south of Salzburg; ice caves are bedrock caves that contain year-round ice formations; they differ from glacial caves, which are transient and are formed by melting ice and flowing water within and under glaciers

Bahrain

close to primary Middle Eastern petroleum sources; strategic location in Persian Gulf, through which much of the Western world's petroleum must transit to reach open ocean

most of the country is situated on deltas of large rivers flowing from the Himalayas: the Ganges unites with the Jamuna (main channel of the Brahmaputra) and later joins the Meghna to eventually empty into the Bay of Bengal

Barbados

easternmost Caribbean island

Botswana

landlocked; sparsely populated with most settlement concentrated in the southern and eastern parts of the country; geography dominated by the Kalahari Desert, which covers about 70% of the country, although the Okavango Delta brings considerable biodiversity as one of the largest inland deltas in the World

note 2: although earthquakes can strike anywhere at any time, the vast majority occur in three large zones of the Earth; the world's greatest earthquake belt, the Circum-Pacific Belt (popularly referred to as the Ring of Fire), is the zone of active volcanoes and earthquake epicenters bordering the Pacific Ocean; about 90% of the World's earthquakes (81% of the largest earthquakes) and some 75% of the World's volcanoes occur within the Ring of Fire; the belt extends northward from Chile, along the South American coast, through Central America, Mexico, the western US, southern Alaska and the Aleutian Islands, to Japan, the Philippines, Papua New Guinea, island groups in the southwestern Pacific, and New Zealand

the second prominent belt, the Alpide, extends from Java to Sumatra, northward along the mountains of Burma, then eastward through the Himalayas, the Mediterranean, and out into the Atlantic Ocean; it accounts for about 17% of the world's largest earthquakes; the third important belt follows the long Mid-Atlantic Ridge
