Question: Compared to other continents, how is the one ranked that has Champness Glacier?

full_context: Document 1: Antarctic Plate: The Antarctic Plate is a tectonic plate containing the continent of Antarctica, the Kerguelen Plateau and extending outward under the surrounding oceans. After breakup from Gondwana (the southern part of the supercontinent Pangea), the Antarctic plate began moving the continent of Antarctica south to its present isolated location causing the continent to develop a much colder climate. The Antarctic Plate is bounded almost entirely by extensional mid-ocean ridge systems. The adjoining plates are the Nazca Plate, the South American Plate, the African Plate, the Somali Plate, the Indo-Australian Plate, the Pacific Plate, and, across a transform boundary, the Scotia Plate.
Document 2: Flensing Icefall: Flensing Icefall is a large icefall at the east side of the Bowers Mountains in Victoria Land, Antarctica, situated south of Platypus Ridge at the junction of Graveson Glacier and Rastorguev Glacier with Lillie Glacier. The icefall was so named by the northern party of the New Zealand Geological Survey Antarctic Expedition, 1963–64, because the icefall's longitudinal system of parallel crevassing resembles the carcass of a whale when being flensed. This glaciological feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 3: Antarctica: Positioned asymmetrically around the South Pole and largely south of the Antarctic Circle, Antarctica is the southernmost continent and is surrounded by the Southern Ocean; alternatively, it may be considered to be surrounded by the southern Pacific, Atlantic, and Indian Oceans, or by the southern waters of the World Ocean. It covers more than 14,000,000 km2 (5,400,000 sq mi), making it the fifth-largest continent, about 1.3 times as large as Europe. The coastline measures 17,968 km (11,165 mi) and is mostly characterized by ice formations, as the following table shows:
Document 4: Beaman Glacier: Beaman Glacier () is a tributary to Ebbe Glacier lying close north of McLean Glacier in the southwest part of the Anare Mountains, a major mountain range situated within the geographical borders of Victoria Land, Antarctica. The glacier was so named by the Advisory Committee on Antarctic Names for First Lieutenant Charles W. Beaman, USA, helicopter pilot who flew missions in support of the United States Geological Survey Topo West survey of this area in the 1962–63 season. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 5: Champness Glacier: Champness Glacier () is a tributary glacier, long, draining northeast from the vicinity of Ian Peak in the Bowers Mountains and entering Lillie Glacier at Griffith Ridge, Victoria Land, Antarctica. The glacier was so named by the New Zealand Geological Survey Antarctic Expedition to northern Victoria Land, 1967–68, for G.R. Champness, field assistant with that party. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 6: Antarctica: Due to its location at the South Pole, Antarctica receives relatively little solar radiation. This means that it is a very cold continent where water is mostly in the form of ice. Precipitation is low (most of Antarctica is a desert) and almost always in the form of snow, which accumulates and forms a giant ice sheet which covers the land. Parts of this ice sheet form moving glaciers known as ice streams, which flow towards the edges of the continent. Next to the continental shore are many ice shelves. These are floating extensions of outflowing glaciers from the continental ice mass. Offshore, temperatures are also low enough that ice is formed from seawater through most of the year. It is important to understand the various types of Antarctic ice to understand possible effects on sea levels and the implications of global cooling.
Document 7: Wilkes Land: Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. It fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole:
Document 8: Ian Peak: Ian Peak is a peak in the Bowers Mountains of Antarctica, northwest of Mount Stirling where the feature overlooks the heads of Leap Year Glacier and Champness Glacier. It was named by the New Zealand Geological Survey Antarctic Expedition, 1967–68, for Ian Smith of the Victoria University of Wellington, a geologist in Antarctica that season. The mountain lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 9: Antarctica: Antarctica (US English i/æntˈɑːrktɪkə/, UK English /ænˈtɑːktɪkə/ or /ænˈtɑːtɪkə/ or /ænˈɑːtɪkə/)[Note 1] is Earth's southernmost continent, containing the geographic South Pole. It is situated in the Antarctic region of the Southern Hemisphere, almost entirely south of the Antarctic Circle, and is surrounded by the Southern Ocean. At 14,000,000 square kilometres (5,400,000 square miles), it is the fifth-largest continent in area after Asia, Africa, North America, and South America. For comparison, Antarctica is nearly twice the size of Australia. About 98% of Antarctica is covered by ice that averages 1.9 km (1.2 mi; 6,200 ft) in thickness, which extends to all but the northernmost reaches of the Antarctic Peninsula.
Document 10: Pennell Coast: Pennell Coast is that portion of the coast of Antarctica between Cape Williams and Cape Adare. To the west of Cape Williams lies Oates Coast, and to the east and south of Cape Adare lies Borchgrevink Coast. Named by New Zealand Antarctic Place-Names Committee (NZ-APC) in 1961 after Lieutenant Harry Pennell, Royal Navy, commander of the Terra Nova, the expedition ship of the British Antarctic Expedition, 1910-13. Pennell engaged in oceanographic work in the Ross Sea during this period. In February 1911 he sailed along this coast in exploration and an endeavor to land the Northern Party led by Lieutenant Victor Campbell.
Document 11: Black Glacier: Black Glacier () is a broad tributary to the Lillie Glacier flowing northeast, marking the southeast extent of the Bowers Mountains, a major mountain range situated in the geographical location of Victoria Land, Antarctica. The glacier was first mapped by the United States Geological Survey from ground surveys and from U.S. Navy air photos, 1960–62, and named by the Advisory Committee on Antarctic Names for Robert F. Black, former geologist of the University of Wisconsin, project leader for Antarctic patterned ground studies, who carried out research in the McMurdo Sound region during several summer seasons in the 1960s. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 12: Antarctica: Antarctica is colder than the Arctic for three reasons. First, much of the continent is more than 3,000 m (9,800 ft) above sea level, and temperature decreases with elevation in the troposphere. Second, the Arctic Ocean covers the north polar zone: the ocean's relative warmth is transferred through the icepack and prevents temperatures in the Arctic regions from reaching the extremes typical of the land surface of Antarctica. Third, the Earth is at aphelion in July (i.e., the Earth is farthest from the Sun in the Antarctic winter), and the Earth is at perihelion in January (i.e., the Earth is closest to the Sun in the Antarctic summer). The orbital distance contributes to a colder Antarctic winter (and a warmer Antarctic summer) but the first two effects have more impact.
Document 13: Carryer Glacier: Carryer Glacier is a heavily crevassed tributary glacier, long, which drains westward from the central part of the Bowers Mountains and enters Rennick Glacier between Mount Soza and Mount Gow, Victoria Land, Antarctica. The glacier was named by the northern party of New Zealand Geological Survey Antarctic Expedition, 1963–64, for S.J. Carryer, former geologist with this party. The glacier lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 14: Wilkes Land: Wilkes Land is a large district of land in eastern Antarctica, formally claimed by Australia as part of the Australian Antarctic Territory, though the validity of this claim has been placed for the period of the operation of the Antarctic Treaty, to which Australia is a signatory. It fronts on the southern Indian Ocean between Queen Mary Coast and Adelie Land, extending from Cape Hordern in 100°31' E to Pourquoi Pas Point, in 136°11' E. The region extends as a sector about 2600 km towards the South Pole, with an estimated land area of 2,600,000 km², mostly glaciated. It is further subdivided in the following coastal areas which can also be thought of as sectors extending to the South Pole:
Document 15: George Glacier: George Glacier is a valley glacier in the western part of the Anare Mountains of Victoria Land, Antarctica. The glacier rises east of Mount Burch and flows northwest past Mount Kelly to Lillie Glacier Tongue on the coast. This geographical feature was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–1965, and was named by the Advisory Committee on Antarctic Names for Robert Y. George, a zoologist at McMurdo Station, Hut Point Peninsula, Ross Island, 1967–1968. The glacier is situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
