Mountain Range
A mountain range or hill range is a series of mountains or hills arranged in a line and connected by high ground. A mountain system or mountain belt is a group of mountain ranges with similarity in form, structure, and alignment that have arisen from the same cause, usually an orogeny. Mountain ranges are formed by a variety of geological processes, but most of the significant ones on Earth are the result of plate tectonics. Mountain ranges are also found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets. Mountain ranges are usually segmented by highlands or mountain passes and valleys. Individual mountains within the same mountain range do not necessarily have the same geologic structure or petrology. They may be a mix of different orogenic expressions and terranes, for example thrust sheets, uplifted blocks, fold mountains, and volcanic landforms resulting in a variety of rock types. Major ranges Most geolo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devon Island
Devon Island ( iu, ᑕᓪᓗᕈᑎᑦ, ) is an island in Canada and the largest uninhabited island (no permanent residents) in the world. It is located in Baffin Bay, Qikiqtaaluk Region, Nunavut, Canada. It is one of the largest members of the Arctic Archipelago, the second-largest of the Queen Elizabeth Islands, Canada's sixth-largest island, and the 27th-largest island in the world. It has an area of (slightly smaller than Croatia). The bedrock is Precambrian gneiss and Paleozoic siltstones and shales. The highest point is the Devon Ice Cap at which is part of the Arctic Cordillera. Devon Island contains several small mountain ranges, such as the Treuter Mountains, Haddington Range and the Cunningham Mountains. The notable similarity of its surface to that of Mars has attracted interest from scientists. History and settlement Robert Bylot and William Baffin were the first Europeans to sight Devon Island in 1616. William Edward Parry charted its south coast in 1819–20, ...

Nunavut
Nunavut ( , ; iu, ᓄᓇᕗᑦ , ; ) is the largest and northernmost Provinces and territories of Canada#Territories, territory of Canada. It was separated officially from the Northwest Territories on April 1, 1999, via the ''Nunavut Act'' and the ''Nunavut Land Claims Agreement, Nunavut Land Claims Agreement Act'', which provided this territory to the Inuit for independent government. The boundaries had been drawn in 1993. The creation of Nunavut resulted in the territorial evolution of Canada, first major change to Canada's political map in half a century since the province of Newfoundland and Labrador, Newfoundland was admitted in 1949. Nunavut comprises a major portion of Northern Canada and most of the Arctic Archipelago. Its vast territory makes it the list of the largest country subdivisions by area, fifth-largest country subdivision in the world, as well as North America's second-largest (after Greenland).

Devon Ice Cap
The Devon Ice Cap is an ice cap on eastern Devon Island, Nunavut, Canada, covering an area of over . The highest point on Devon Island is found at the summit of the ice cap, with an elevation of . The ice cap has a maximum thickness of , and has been steadily shrinking since 1985. The first ascent of the Devon Ice Cap was by Alfred Herbert Joy and his Inuit companions in 1926. Geology The Devon Ice Cap and the Agassiz Ice Cap on the neighboring Ellesmere Island are two of the largest ice caps in the Arctic Cordillera in the Canadian Arctic, and consist of a substantial fraction of ice not locked away in the Antarctic and Greenland ice sheets. As such, should the entire Devon Ice Cap melt due to global warming, the ice will contribute approximately 1 centimeter to global sea level rise. The Devon Ice Cap has a dome-like structure and a maximum elevation of 1921 m above sea level at its summit, and the maximum ice thickness is 880 m. There are two distinct regions in t ...

Arctic Cordillera
The Arctic Cordillera is a terrestrial ecozone in northern Canada characterized by a vast, deeply dissected chain of mountain ranges extending along the northeastern flank of the Canadian Arctic Archipelago from Ellesmere Island to the northeasternmost part of the Labrador Peninsula in northern Labrador and northern Quebec, Canada. It spans most of the eastern coast of Nunavut with high glaciated peaks rising through ice fields and some of Canada's largest ice caps, including the Penny Ice Cap on Baffin Island. It is bounded to the east by Baffin Bay, Davis Strait and the Labrador Sea while its northern portion is bounded by the Arctic Ocean. Overview The range is mostly located in Nunavut but extends southeast into the northernmost tip of Labrador and northeastern Quebec. The system is divided into a series of ranges, with mountains reaching heights of more than . The highest is Barbeau Peak on Ellesmere Island at , which is the highest point in eastern North America.

List Of Mountain Ranges
This is a list of mountain ranges on Earth and a few other astronomical bodies. First, the highest and longest mountain ranges on Earth are listed, followed by more comprehensive alphabetical lists organized by continent. Ranges in the oceans and on other celestial bodies are listed afterwards. Mountain ranges on planet Earth By size Note 1: A peak included in the "Eastern Pamirs" more often than in the Kunlun Mountains, as Kongur Tagh and the Kunlun range are ''separated'' by the large Yarkand River valley; no valley of such significance separates the Pamirs and Kongur Tagh, just political boundaries. Note 2: Part of Hindu Kush-Himalayas region All of the Asian ranges above have been formed in part over the past 35 to 55 million years by the collision between the Indian Plate and Eurasian Plate. The Indian Plate is still particularly mobile and these mountain ranges continue to rise in elevation every year and this page may need to be updated in a few years; of these th ...

Mountain Ranges Of Qikiqtaaluk Region
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 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 isolated summits, but most occur in mountain ranges. Mountains are formed through 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 slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
