List of island countries
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.
World Park Base
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.
Cigarette Rock
Cigarette Rock is a summit in Lewis and Clark County, Montana, in the United States. With an elevation of , Cigarette Rock is the 799th highest summit in Montana.
Continental shelf
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 °.
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.
Stewart Peak (Colorado)
Stewart Peak, elevation , is a summit in Colorado. The peak is the second highest thirteener (a peak between 13,000 and 13,999 feet in elevation) in the state. It is located in the La Garita Mountains, sub-range of the San Juan Mountains, in Saguache County, within the La Garita Wilderness. Stewart Peak is the 55th highest peak in Colorado by most standard definitions, just missing the list of Colorado fourteeners. At one time, the peak's elevation was measured to be over 14,000 ft and it was believed to be a fourteener, but more recent and accurate surveys have dropped it below that threshold.
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.
Siguang Ri
Siguang Ri is a mountain in the Mahalangur Himalayas of Tibet, China. At an elevation of it is the 83rd highest peak on Earth. It is located approximately 6 kilometers NNE of Cho Oyu, the world's 6th highest mountain.
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.
Monte Solaro
Monte Solaro is a mountain on the island of Capri in Campania, Italy. With an elevation of 589 m, its peak is the highest point of Capri.
Seetalhorn
The Seetalhorn is a mountain of the Swiss Pennine Alps, overlooking Grächen in the canton of Valais. With an elevation of 3,037 m, it is the highest point of the ski area of Grächen.
List of mountain peaks of the Caribbean
Of the 20 highest major summits of the Caribbean, only Pico Duarte exceeds 3000 meters (9843 feet) elevation, six peaks exceed 2000 meters (6562 feet), and 15 peaks exceed 1000 meters (3281 feet) elevation.
Tibet
Tibet (i/tᵻˈbɛt/; Wylie: Bod, pronounced [pʰø̀ʔ]; Chinese: 西藏; pinyin: Xīzàng) is a region on the Tibetan Plateau in Asia. It is the traditional homeland of the Tibetan people as well as some other ethnic groups such as Monpa, Qiang and Lhoba peoples and is now also inhabited by considerable numbers of Han Chinese and Hui people. Tibet is the highest region on Earth, with an average elevation of 4,900 metres (16,000 ft). The highest elevation in Tibet is Mount Everest, earth's highest mountain rising 8,848 m (29,029 ft) above sea level.
Antarctica
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.
Antarctica
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.
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).
Dalhousie Mountain
Dalhousie Mountain is a Canadian peak in the Cobequid Mountains and the highest elevation point in Pictou County, Nova Scotia.
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.
List of U.S. states and territories by elevation
Which state or territory is ``highest ''and`` lowest'' is determined by the definition of ``high ''and`` low''. For instance, Alaska could be regarded as the highest state because Denali, at 20,310 feet (6,190.5 m), is the highest point in the United States. However, Colorado, with the highest mean elevation of any state as well as the highest low point, could also be considered a candidate for ``highest state ''. Determining which state is`` lowest'' is equally problematic. California contains the Badwater Basin in Death Valley, at 279 feet (85 m) below sea level, the lowest point in the United States; while Florida has the lowest high point, and Delaware has the lowest mean elevation. Florida is also the flattest state, with the smallest difference between its highest and lowest points.
Continental shelf
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.
