South America
Brazil is the largest country in South America, encompassing around half of the continent's land area and population. The remaining countries and territories are divided among three regions: The Andean States, the Guianas and the Southern Cone.
Live Earth concert, Antarctica
The Live Earth concert in Antarctica was held at Rothera Research Station, one in a series of Live Earth concerts that took place on July 7, 2007, in all seven continents. The band Nunatak performed as the lone act. Nunatak's performances, though performed in front of only 17 people, were broadcast all over the world. It was the first rock concert ever performed in Antarctica.
Zealandia
Zealandia (/ ziːˈlændiə /), also known as the New Zealand continent or Tasmantis, is a nearly submerged mass of continental crust that sank after breaking away from Australia 60 -- 85 million years ago, having separated from Antarctica between 85 and 130 million years ago. It has variously been described as a continental fragment, a microcontinent and a continent. The name and concept for Zealandia were proposed by Bruce Luyendyk in 1995.
Geological history of Earth
The Ordovician Period started at a major extinction event called the Cambrian-Ordovician extinction events some time about 485.4 ± 1.9 Ma. During the Ordovician the southern continents were collected into a single continent called Gondwana. Gondwana started the period in the equatorial latitudes and, as the period progressed, drifted toward the South Pole. Early in the Ordovician the continents Laurentia, Siberia and Baltica were still independent continents (since the break-up of the supercontinent Pannotia earlier), but Baltica began to move toward Laurentia later in the period, causing the Iapetus Ocean to shrink between them. Also, Avalonia broke free from Gondwana and began to head north toward Laurentia. The Rheic Ocean was formed as a result of this. By the end of the period, Gondwana had neared or approached the pole and was largely glaciated.
Seafloor spreading
Earlier theories (e.g. by Alfred Wegener and Alexander du Toit) of continental drift postulated that continents ``ploughed ''through the sea. The idea that the seafloor itself moves (and also carries the continents with it) as it expands from a central axis was proposed by Harry Hess from Princeton University in the 1960s. The theory is well accepted now, and the phenomenon is known to be caused by convection currents in the asthenosphere, which is ductile, or plastic, and the brittle lithosphere (crust and upper mantle).
MacDonald Nunataks
The MacDonald Nunataks () are two nunataks overlooking the head of the Ross Ice Shelf, Antarctica, standing just east of the terminus of Amundsen Glacier, west of O'Brien Peak. They were mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–64, and were named by the Advisory Committee on Antarctic Names for John A. MacDonald, a biologist with the McMurdo Station winter party, 1964.
Australia (continent)
New Zealand is not part of the continent of Australia, but of the separate, submerged continent of Zealandia. New Zealand and Australia are both part of the Oceanian sub-region known as Australasia, with New Guinea being in Melanesia. The term Oceania is often used to denote the region encompassing the Australian continent and various islands in the Pacific Ocean that are not included in the seven - continent model.
Antarctica
Antarctica, on average, is the coldest, driest, and windiest continent, and has the highest average elevation of all the continents. Antarctica is considered a desert, with annual precipitation of only 200 mm (8 in) along the coast and far less inland. The temperature in Antarctica has reached −89.2 °C (−128.6 °F), though the average for the third quarter (the coldest part of the year) is −63 °C (−81 °F). There are no permanent human residents, but anywhere from 1,000 to 5,000 people reside throughout the year at the research stations scattered across the continent. Organisms native to Antarctica include many types of algae, bacteria, fungi, plants, protista, and certain animals, such as mites, nematodes, penguins, seals and tardigrades. Vegetation, where it occurs, is tundra.
Argentinosaurus
Argentinosaurus (meaning "Argentine lizard") is a genus of titanosaur sauropod dinosaur first discovered by Guillermo Heredia in Argentina. The generic name refers to the country in which it was discovered. The dinosaur lived on the then-island continent of South America somewhere between 97 and 93.5 million years ago, during the Late Cretaceous Period. It is among the largest known dinosaurs.
Africa
Africa is the world's second - largest and second-most - populous continent (the first being Asia). At about 30.3 million km (11.7 million square miles) including adjacent islands, it covers 6% of Earth's total surface area and 20.4% of its total land area. With 1.2 billion people as of 2016, it accounts for about 16% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognised sovereign states (countries), nine territories and two de facto independent states with limited or no recognition.
Antarctica
Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:
Antarctic oasis
An Antarctic oasis is a large area naturally free of snow and ice in the otherwise ice-covered continent of Antarctica.
Consequences of War
Consequences of War, also known as "Horror of war", was executed between 1638-1639 by Peter Paul Rubens in oil paint on canvas. It was painted for Ferdinando II de' Medici. Although commissioned by an Italian, art historians characterize both the work and the artist as Flemish Baroque. It serves as a commentary on a European continent ravaged by the Thirty Years' War, and the artist employed numerous symbols, both contemporary and ancient, to deplore the state of the continent.
Emilio Palma
Emilio Marcos Palma (born 7 January 1978) is an Argentine man known for being the first documented person born on the continent of Antarctica.
The Continent Makers
The Continent Makers is a science fiction novella by American writers L. Sprague de Camp, part of his "Viagens Interplanetarias" series. It was first published in the magazine "Thrilling Wonder Stories" in the issue for April, 1951. It first appeared in book form in the collection "The Continent Makers and Other Tales of the Viagens", published in hardcover by Twayne Publishers in 1953, and in paperback by Signet Books in 1971. It has also been translated into Portuguese, Dutch, and Italian.
Continental drift
Continental drift is the movement of the Earth's continents relative to each other, thus appearing to ``drift ''across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596. The concept was independently and more fully developed by Alfred Wegener in 1912, but his theory was rejected by some for lack of a mechanism (though this was supplied later by Arthur Holmes). The idea of continental drift has been subsumed by the theory of plate tectonics, which explains how the continents move.
Continent
A continent is one of several very large landmasses of the world. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in size to smallest, they are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia.
Elliott Hills
The Elliott Hills () are a group of low hills and nunataks, long, that mark the northwest end of the Gutenko Mountains, in central Palmer Land, Antarctica. They were mapped by the United States Geological Survey in 1974, and were named by the Advisory Committee on Antarctic Names for Lieutenant Commander David J. Elliott, U.S. Navy, Commander of LC-130 aircraft in aerial photographic and ice-sensing flights over extensive areas of the Antarctic continent during Operation Deep Freeze, 1970 and 1971.
