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] |

Dennistoun Glacier
The Dennistoun Glacier is a glacier, long, draining the northern slopes of Mounts Black Prince, Royalist and Adam in the Admiralty Mountains of Victoria Land in Antarctica. It flows northwest between the Lyttelton Range and Dunedin Range, turning east on rounding the latter range to enter the sea south of Cape Scott. The coastal extremity of the glacier was charted in 1911–12 by the Northern Party, led by Victor Campbell, of the British Antarctic Expedition, 1910–13. The geographical feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare. The glacier is named after Jim Dennistoun, a New Zealand alpinist who was in charge of the mules on board the '' Terra Nova'' on her way to Antarctica. The entire extent of the glacier was mapped by the U.S. Geological Survey from surveys and U.S. Navy aerial photography, 1960–63. The name Fowlie Glacier, which in fact refers to a tributary glacier, has sometimes been inadvertently ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility. The agency was founded on March 3, 1879. The USGS is a bureau of the United States Department of the Interior; it is that department's sole scientific agency.

Advisory Committee On Antarctic Names
The Advisory Committee on Antarctic Names (ACAN or US-ACAN) is an advisory committee of the United States Board on Geographic Names responsible for recommending commemorative names for features in Antarctica. History The committee was established in 1943 as the Special Committee on Antarctic Names (SCAN). It became the Advisory Committee on Antarctic Names in 1947. Fred G. Alberts was Secretary of the Committee from 1949 to 1980. By 1959, a structured nomenclature was reached, allowing for further exploration, structured mapping of the region and a unique naming system. A 1990 ACAN gazeeter of Antarctica listed 16,000 names. Description The United States does not recognise territorial boundaries within Antarctica, so ACAN assigns names to features anywhere within the continent, in consultation with other national nomenclature bodies where appropriate, as defined by the Antarctic Treaty System. The research and staff support for the ACAN is provided by the United States Geologi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyttelton, New Zealand
Lyttelton (Māori: ''Ōhinehou'') is a port town on the north shore of Lyttelton Harbour / Whakaraupō, at the northwestern end of Banks Peninsula and close to Christchurch, on the eastern coast of the South Island of New Zealand. As a landing point for Christchurch-bound seafarers, Lyttelton has historically been regarded as the "Gateway to Canterbury" for colonial settlers. Until the 2020 coronavirus pandemic, the port has been a regular destination for cruise ships. It is the South Island's principal goods-transport terminal, handling 34% of exports and 61% of imports by value. In 2009 Lyttelton was awarded Category I Historic Area status by the Historic Places Trust (NZHPT) defined as "an area of special or outstanding historical or cultural heritage significance or value", not long before much of the historic fabric was destroyed in the 2011 Christchurch earthquake. Location Lyttelton is the largest settlement on Lyttelton Harbour / Whakaraupō, an inlet on the northwe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mountain Ranges Of The Ross Dependency
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 ...
