paragraph_text: Gulch Island () is an island lying northwest of Small Island in the Christiania Islands, in the Palmer Archipelago, Antarctica. The island is shown on an Argentine government chart of 1952. Gulch Island was so named by the UK Antarctic Place-Names Committee in 1960 because the island is deeply indented.

paragraph_text: The climate of the United States varies due to differences in latitude, and a range of geographic features, including mountains and deserts. West of the 100th meridian, much of the US is semi-arid to desert in the far southwestern US, and Mediterranean along the California coast. East of the 100th meridian, the climate is humid continental in the northern areas east through New England, to humid subtropical in the Gulf and South Atlantic regions. Southern Florida is tropical, as is Hawaii and the US Virgin Islands. Higher - elevation areas of the Rocky Mountains, the Wasatch, Sierra Nevada, and Cascade Range are alpine. The West Coast areas in coastal Oregon and Washington are oceanic climate. The state of Alaska, on the northwestern corner of the North American continent, is largely subarctic climate, but with a subpolar oceanic climate in the southeast (Alaska Panhandle), southwestern peninsula and Aleutian Islands.

paragraph_text: This is a list of island countries. An island is a land mass (smaller than a continent) that is surrounded by water. Many island countries are spread over an archipelago, as is the case with the Federated States of Micronesia and the Indonesia (which consists of thousands of islands). Others consist of a single island, such as Nauru, or part of an island, such as Haiti. Although Australia is designated as a continent, it is often referred to as an island, as it has no land borders. Some declared island countries are not universally recognized as politically independent, such as Northern Cyprus. Some states, such as Taiwan, officially claim to hold continental territories but are de facto limited to control over islands.

paragraph_text: In colonial times, the Thirteen Colonies used a militia system for defense. Colonial militia laws -- and after independence those of the United States and the various states -- required able - bodied males to enroll in the militia, to undergo a minimum of military training, and to serve for limited periods of time in war or emergency. This earliest form of conscription involved selective drafts of militiamen for service in particular campaigns. Following this system in its essentials, the Continental Congress in 1778 recommended that the states draft men from their militias for one year's service in the Continental army; this first national conscription was irregularly applied and failed to fill the Continental ranks.

paragraph_text: Crystal Sound () is a sound in Antarctica between the southern part of the Biscoe Islands and the coast of Graham Land, with northern limit Cape Evensen to Cape Leblond and southern limit Holdfast Point, Roux Island, Liard Island and the Sillard Islands. It was so named by the UK Antarctic Place-Names Committee in 1960 because many features in the sound are named for men who have undertaken research on the structure of ice crystals.

paragraph_text: 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.

paragraph_text: 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.

paragraph_text: 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.

paragraph_text: Due to its location at the South Pole, Antarctica receives relatively little solar radiation. This means that it is a very cold continent where water is mostly in the form of ice. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. Next to the continental shore are many ice shelves. These are floating extensions of outflowing glaciers from the continental ice mass. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling.

paragraph_text: Emilio Marcos Palma was the first person born south of the 60th parallel south (the continental limit according to the Antarctic Treaty), as well as the first one born on the Antarctic mainland, in 1978 at Base Esperanza, on the tip of the Antarctic Peninsula; his parents were sent there along with seven other families by the Argentine government to determine if the continent was suitable for family life. In 1984, Juan Pablo Camacho was born at the Frei Montalva Station, becoming the first Chilean born in Antarctica. Several bases are now home to families with children attending schools at the station. As of 2009, eleven children were born in Antarctica (south of the 60th parallel south): eight at the Argentine Esperanza Base and three at the Chilean Frei Montalva Station.

paragraph_text: The Battle of Rhode Island (also known as the Battle of Quaker Hill and the Battle of Newport) took place on August 29, 1778. Continental Army and militia forces under the command of General John Sullivan had been besieging the British forces in Newport, Rhode Island, which is situated on Aquidneck Island, but they had finally abandoned their siege and were withdrawing to the northern part of the island. The British forces then sortied, supported by recently arrived Royal Navy ships, and they attacked the retreating Americans. The battle ended inconclusively, but the Continental forces withdrew to the mainland and left Aquidneck Island in British hands.

paragraph_text: The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope followed by the flatter continental rise. Sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope, called the continental rise. Extending as far as 500 km (310 mi) from the slope, it consists of thick sediments deposited by turbidity currents from the shelf and slope. The continental rise's gradient is intermediate between the slope and the shelf, on the order of 0.5 -- 1 °.

paragraph_text: World Park Base was a non-governmental year-round Antarctic base located at Cape Evans on Ross Island in the Ross Dependency. The international environmental organization Greenpeace established World Park Base in 1987 in order to press its demand for the Antarctic Treaty nations to declare all of the continent of Antarctica a World Park. This would make the entire continent off-limits to commercial exploitation and pollution, and permit only limited scientific research. Greenpeace closed down and completely dismantled the base in 1992.

paragraph_text: Iceland is closer to continental Europe than to mainland North America, although it is closest to Greenland (290 km, 180 mi), an island of North America. Iceland is generally included in Europe for historical, political, cultural, geographical, and practical reasons. Geologically, the island includes parts of both continental plates. The closest bodies of land in Europe are the Faroe Islands (420 km, 260 mi); Jan Mayen Island (570 km, 350 mi); Shetland and the Outer Hebrides, both about 740 km (460 mi); and the Scottish mainland and Orkney, both about 750 km (470 mi). The nearest part of Continental Europe is mainland Norway, about 970 km (600 mi) away, while mainland North America is 2,070 km (1,290 mi) away, at the northern tip of Labrador.

paragraph_text: The Cambrian is a major division of the geologic timescale that begins about 541.0 ± 1.0 Ma. Cambrian continents are thought to have resulted from the breakup of a Neoproterozoic supercontinent called Pannotia. The waters of the Cambrian period appear to have been widespread and shallow. Continental drift rates may have been anomalously high. Laurentia, Baltica and Siberia remained independent continents following the break-up of the supercontinent of Pannotia. Gondwana started to drift toward the South Pole. Panthalassa covered most of the southern hemisphere, and minor oceans included the Proto-Tethys Ocean, Iapetus Ocean and Khanty Ocean.

paragraph_text: On Earth, 99% of glacial ice is contained within vast ice sheets in the polar regions, but glaciers may be found in mountain ranges on every continent except Australia, and on a few high-latitude oceanic islands. Between 35°N and 35°S, glaciers occur only in the Himalayas, Andes, Rocky Mountains, a few high mountains in East Africa, Mexico, New Guinea and on Zard Kuh in Iran. Glaciers cover about 10 percent of Earth's land surface. Continental glaciers cover nearly 13,000,000 km2 (5×10^6 sq mi) or about 98 percent of Antarctica's 13,200,000 km2 (5.1×10^6 sq mi), with an average thickness of 2,100 m (7,000 ft). Greenland and Patagonia also have huge expanses of continental glaciers.

paragraph_text: 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.

paragraph_text: Africa is the world's second largest and second most - populous continent (behind Asia in both categories). 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% of its 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, the Isthmus of Suez and the Red Sea 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. The majority of the continent and its countries are in the Northern Hemisphere, with a substantial portion and number of countries in the Southern Hemisphere.

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).
