⭐ Core Definition: List of glaciers

A glacier (US: /ˈɡlʃər/ GLAY-shər) or (UK: /ˈɡlæsiə/) is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries. Glaciers slowly deform and flow due to stresses induced by their weight, creating crevasses, seracs, and other distinguishing features. Because glacial mass is affected by long-term climate changes, e.g., precipitation, mean temperature, and cloud cover, glacial mass changes are considered among the most sensitive indicators of climate change. There are about 198,000 to 200,000 glaciers in the world.

List of glaciers in the context of Glaciers

A glacier (US: /ˈɡlʃər/; UK: /ˈɡlæsiə/ or /ˈɡlsiə/) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.

On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only in the Himalayas, Andes, and a few high mountains in East Africa, Mexico, New Guinea and on Zard-Kuh in Iran. With more than 7,000 known glaciers, Pakistan has more glacial ice than any other country outside the polar regions. Glaciers cover about 10% of Earth's land surface. Continental glaciers cover nearly 13 million km (5 million sq mi) or about 98% of Antarctica's 13.2 million km (5.1 million sq mi), with an average thickness of ice 2,100 m (7,000 ft). Greenland and Patagonia also have huge expanses of continental glaciers. The volume of glaciers, not including the ice sheets of Antarctica and Greenland, has been estimated at 170,000 km.

List of glaciers in the context of Siachen Glacier

The Siachen Glacier is a glacier located in the eastern Karakoram range of the Himalayas, just northeast of the point NJ9842 where the Line of Control between India and Pakistan ends in northeastern Kashmir. At 76 km (47 mi) long, it is the longest glacier in the Karakoram and second-longest in the world's non-polar areas. It falls from an altitude of 5,753 m (18,875 ft) above sea level at its head at Indira Col on the India–China border down to 3,620 m (11,875 ft) at its terminus. The entire Siachen Glacier, with all major passes, has been under the administration of India as part of the union territory of Ladakh since 1984. Pakistan maintains a territorial claim over the Siachen Glacier and controls the region west of Saltoro Ridge, lying west of the glacier, with Pakistani posts located 1 km below more than 100 Indian posts on the ridge.

The Siachen Glacier lies immediately south of the great drainage divide that separates the Eurasian Plate from the Indian subcontinent in the extensively glaciated portion of the Karakoram sometimes called the "Third Pole". The glacier lies between the Saltoro Ridge immediately to the west and the main Karakoram range to the east. The Saltoro Ridge originates in the north from the Sia Kangri peak on the China border in the Karakoram range. The crest of the Saltoro Ridge's altitudes range from 5,450 to 7,720 m (17,880 to 25,330 feet). The major passes on this ridge are, from north to south, Sia La at 5,589 m (18,336 ft), Bilafond La at 5,450 m (17,880 ft), and Gyong La at 5,689 m (18,665 ft). The average winter snowfall is more than 1000 cm (35 ft) and temperatures can dip to −50 °C (−58 °F). Including all tributary glaciers, the Siachen Glacier system covers about 700 km (270 sq mi).

List of glaciers in the context of Northern Pakistan

Northern Pakistan (Urdu: شمالی پاکستان ALA-LC: śimālī Pākistān) is a tourism region in the northern and north-western parts of Pakistan, comprising the administrative units of Gilgit-Baltistan (formerly known as Northern Areas), Azad Kashmir, Khyber Pakhtunkhwa, Islamabad Capital Territory and the Rawalpindi Division in Punjab. The first two territories are Pakistani-administered sectors of the wider Kashmir region. Northern Pakistan is a mountainous region straddling the Himalayas, Karakoram and the Hindu Kush mountain ranges, containing many of the highest peaks in the world and some of the longest glaciers outside polar regions. Northern Pakistan accounts for a high level of Pakistan's tourism industry.
