Canyon
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jøkulkyrkja Mountain
Jøkulkyrkja Mountain ("the Glacier Church"), also known as Massiv Yakova Gakkelya, is a broad, ice-topped mountain with several radial rock spurs, standing east of Lunde Glacier in the Mühlig-Hofmann Mountains of Queen Maud Land, East Antarctica. At elevation, it is the highest elevation in Queen Maud Land, and also the highest elevation within the claims of Norway. The mountain is located on the Princess Astrid Coast of the Norwegian Antarctic Territory. Håhellerskarvet ("shark cave mountain"), , is located to the southwest; the two peaks are separated by the 25-mile-long Lunde Glacier, which flows to the northwest. Discovery and naming Jøkulkyrkja Mountain was plotted from surveys and air photos by the Sixth Norwegian Antarctic Expedition (1956–60) and named ''Jøkulkyrkja''. The first element is ''jøkul'' m 'small glacier', the last element is the finite form of ''kyrkje'' f 'church'. (Like other names in the Norwegian Arctic and Antarctic islands and areas the Nyn ...

Mühlig-Hofmann Mountains
The Mühlig-Hofmann Mountains (german: Mühlig-Hofmann-Gebirge) is a major group of associated mountain features extending east to west for between the Gjelsvik Mountains and the Orvin Mountains in Queen Maud Land, East Antarctica. With its summit at , the massive Jøkulkyrkja Mountain forms the highest point in the Mühlig-Hofmann Mountains. Discovery and naming The Mühlig-Hofmann Mountains were discovered by the Third German Antarctic Expedition (1938-1939), led by Capt. Alfred Ritscher, and named for the division director of the German Air Ministry. They were remapped by the Norwegian Antarctic Expedition, 1956-1960.

Queen Maud Land
Queen Maud Land ( no, Dronning Maud Land) is a roughly region of Antarctica claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20° west and the Australian Antarctic Territory 45° east. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian queen Maud of Wales (1869–1938). In 1930, the Norwegian Hjalmar Riiser-Larsen was the first person known to have set foot in the territory. On 14 January 1939, the territory was claimed by Norway. On 23 June 1961, Queen Maud Land became part of the Antarctic Treaty System, making it a demilitarised zone. It is one of two Antarctic claims made by Norway, the other being Peter I Island. They are administered by the Polar Affairs Department of the Norwegian Ministry of Justice and Public Security in Oslo. Most of the territory is covered by the east Antarctic ic ...

Sixth Norwegian Antarctic Expedition
The sixth Norwegian Antarctic Expedition (''Den norske antarktisekspedisjonen'') was a scientific expedition to Queen Maud Land in Antarctica. The expedition was based at Norway Station () which was located on the Fimbul Ice Shelf bordering the coast of Queen Maud Land. The expedition carried out survey work and scientific studies over a period of three-four years (1956–1960). The expedition was intended as part of Norway's participation in the International Geophysical Year, 1957-58. The crew set sail from Oslo on board two whaling ships, the ''Polarsirkel'' and ''Polarbjørn'', on 10 November 1956. The expedition was led by Sigurd Gunnarson Helle, a geodesist at Norsk Polarinstitutt. It included a total crew of fourteen researchers which was reduced to nine during the third year. Among their activities were topological mapping of the region. In 1960, King Olav V of Norway instituted the Antarctic Medal The Antarctic Medal is a civil decoration of Norway. Established by ...

Landforms Of Queen Maud Land
A landform is a natural or anthropogenic land feature on the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, Stratum, stratification, rock exposure and soil type. Gross physical features or landforms include intuitive elements such as berms, mounds, hills, ridges, cliffs, valleys, rivers, peninsulas, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountain A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock.
