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 ...

Devon Island
Devon Island (, ) is an island in Canada and the largest desert island, 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 List of Canadian islands by area, sixth-largest island, and the List of islands by area, 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 Parr ...

Nunavut
Nunavut 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 self-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 (now Newfoundland and Labrador) 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). The capital Iqaluit (formerly "Frobisher Bay"), on Baffin Island in ...

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 ...

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. The geographic range is composed along the provinces of Labrador: including Eastern Baffin, Devon Island, Ellesmere, Bylot Island, the Torngat Mountains, and some parts of the Northeastern fringe. The landscape is dominated by massive polar icefields, alpine glaciers, inland fjords, and large bordering bodies of water, distinctive o ...

List Of Mountain Ranges
This is a list of mountain ranges on Earth and a few other astronomical object, 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 Earth By height * Part of the 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 the Himalayas are rising most quickly; the Kashmir and Pamirs region to the north of the Indian subcontinent is the point of confluence of these mountains which encircle the Tibetan Plateau.

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 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 climate, mountains t ...
