Mount Oceanite
Mount Oceanite () is a conspicuous ice-covered mountain (probably an extinct volcano) rising to in the extreme southeast corner of Montagu Island, South Sandwich Islands. The name, applied by United Kingdom Antarctic Place-Names Committee The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and ... (UK-APC) in 1971, refers to the oceanite lavas present in this area, which occur nowhere else in the South Sandwich Islands. References External links * Oceanite, Mount {{SouthGeorgia-geo-stub ...

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Montagu Island
Montagu Island ( es, Isla Jorge) is the largest of the South Sandwich Islands, located in the Scotia Sea off the coast of Antarctica. It is a part of the British Overseas Territory, South Georgia and the South Sandwich Islands. It is located northeast from Bristol Island and south from Saunders Island. The island was first sighted by James Cook in 1775, and named after John Montagu, 4th Earl of Sandwich and the First Lord of the British Admiralty at the time of its discovery. The first recorded landing was made by the Norwegian whaler and explorer Carl Anton Larsen in 1908. Geography The desolate, uninhabited island measures approximately , with over 90% of its surface permanently covered in ice. The volcano Mount Belinda is its most notable geographic feature, rising to above sea level. It was believed to be inactive prior to the sighting of low-level ash emission and suspected lava effusion in 2002 by the British Antarctic Survey. Mount Belinda In November 2005, satellit ...

United Kingdom Antarctic Place-Names Committee
The UK Antarctic Place-Names Committee (or UK-APC) is a United Kingdom government committee, part of the Foreign and Commonwealth Office, responsible for recommending names of geographical locations within the British Antarctic Territory (BAT) and the South Georgia and the South Sandwich Islands (SGSSI). Such names are formally approved by the Commissioners of the BAT and SGSSI respectively, and published in the BAT Gazetteer and the SGSSI Gazetteer maintained by the Committee. The BAT names are also published in the international Composite Gazetteer of Antarctica maintained by SCAR. The Committee may also consider proposals for new place names for geographical features in areas of Antarctica outside BAT and SGSSI, which are referred to other Antarctic place-naming authorities, or decided by the Committee itself if situated in the unclaimed sector of Antarctica. Names attributed by the committee * Anvil Crag, named for descriptive features * Anckorn Nunataks, named after J. F. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
