Question: What is the size of the continent where King Ridge is located?

full_context: Document 1: Galan Ridge: Galan Ridge is a prominent ridge which forms the northeastern rampart of the Dana Mountains in Palmer Land, Antarctica. It was mapped by the United States Geological Survey from ground surveys and U.S. Navy air photos, 1961–67, and was named by the Advisory Committee on Antarctic Names for Michael P. Galan, a member of the McMurdo Station winter party in 1967 and of the South Pole—Queen Maud Land Traverse III in 1967–68.
Document 2: 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 3: Folk Ridge: Folk Ridge () is a ridge just southeast of Moore Ridge and parallel to it in the Caudal Hills of Victoria Land, Antarctica. The ridge was first mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1960–64, and was named by the Advisory Committee on Antarctic Names for John E. Folk, a biolab technician at McMurdo Station, Hut Point Peninsula, Ross Island, 1965–66. The feature lies situated on the Pennell Coast, a portion of Antarctica lying between Cape Williams and Cape Adare.
Document 4: 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 5: King Ridge: King Ridge () is a narrow rock ridge, long, lying southwest of Wrigley Bluffs in the Anderson Hills in the central Patuxent Range of the Pensacola Mountains, Antarctica. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1956–66. The ridge was named by the Advisory Committee on Antarctic Names at the suggestion of Captain Finn Ronne, U.S. Navy Reserve, leader at Ellsworth Station, 1957: Colonel J. Caldwell King, U.S. Army, had assisted Ronne in obtaining support for the Ronne Antarctic Research Expedition, 1947–48.
Document 6: Benson Ridge: Benson Ridge () is a rugged ridge between Robb Glacier and Bondeson Glacier in Antarctica, standing west of the north end of the Holland Range. It was mapped by the United States Geological Survey from tellurometer surveys and from Navy air photos, 1960–62, and named by the Advisory Committee on Antarctic Names for Carl S. Benson, a United States Antarctic Research Program glaciologist at Roosevelt Island, 1961–62.
Document 7: Hagey Ridge: Hagey Ridge () is a high snow-covered ridge, between the Björnert Cliffs and Johnson Glacier, forming the east end of the McDonald Heights on the coast of Marie Byrd Land, Antarctica. The ridge was first photographed from an aircraft of the U.S. Antarctic Service in December 1940. It was mapped by the United States Geological Survey from surveys and U.S. Navy air photos, 1959–66, and was named by the Advisory Committee on Antarctic Names for Lieutenant Donald W. Hagey, U.S. Navy, Officer-in-Charge at Byrd Station in 1969.
Document 8: 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 9: Pagoda Ridge: Pagoda Ridge () is a ridge with a small peak resembling a pagoda at the summit, located between Phobos Ridge and Deimos Ridge on the north side of Saturn Glacier, in southeast Alexander Island, Antarctica. The feature was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, during 1947 and 1948, and from surveying by the Falkland Islands Dependencies Survey, 1948-50. This descriptive name was applied by the United Kingdom Antarctic Place-Names Committee.
Document 10: Ice sheet: The Antarctic ice sheet is the largest single mass of ice on Earth. It covers an area of almost 14 million km and contains 30 million km of ice. Around 90% of the Earth's ice mass is in Antarctica, which, if melted, would cause sea levels to rise by 58 meters. The continent - wide average surface temperature trend of Antarctica is positive and significant at > 0.05 ° C / decade since 1957.
Document 11: Antarctica: About 98% of Antarctica is covered by the Antarctic ice sheet, a sheet of ice averaging at least 1.6 km (1.0 mi) thick. The continent has about 90% of the world's ice (and thereby about 70% of the world's fresh water). If all of this ice were melted, sea levels would rise about 60 m (200 ft). In most of the interior of the continent, precipitation is very low, down to 20 mm (0.8 in) per year; in a few "blue ice" areas precipitation is lower than mass loss by sublimation and so the local mass balance is negative. In the dry valleys, the same effect occurs over a rock base, leading to a desiccated landscape.
Document 12: 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 13: 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 14: Grikurov Ridge: Grikurov Ridge () is a ridge that extends westward for about from the south end of the LeMay Range, in central Alexander Island, Antarctica. The feature was mapped from trimetrogon air photography taken by the Ronne Antarctic Research Expedition, 1947–48, and from survey by the Falkland Islands Dependencies Survey, 1948–50. It was named by the UK Antarctic Place-Names Committee for the Russian Garrik Grikurov, a Soviet exchange geologist with the British Antarctic Survey, who worked in this area in 1963–64.
Document 15: Martin Ridge: Martin Ridge () is a broad ice-covered ridge bordering the west side of upper Moody Glacier in the Queen Alexandra Range, Antarctica. It was named by the Advisory Committee on Antarctic Names for Major Wilbur E. Martin, U.S.Army, who was in charge of trail operations during U.S. Navy Operation Deep Freeze, 1963.
