Input (English): Context: Aconcagua is the highest mountain outside Asia, at , and by extension the highest point in both the Western Hemisphere and the Southern Hemisphere. It is located in the Andes mountain range, in the Mendoza Province, Argentina, and lies 112 kilometres (70 mi) northwest of its capital, the city of Mendoza. The summit is also located about 5 kilometers from San Juan Province and 15 kilometers from the international border with Chile. The mountain itself lies entirely within Argentina and immediately east of Argentina's border with Chile. Its nearest higher neighbor is Tirich Mir in the Hindu Kush, away. It is one of the Seven Summits., Toronto is the most populous city in Canada, the provincial capital of Ontario, and the centre of the Greater Toronto Area, the most populous metropolitan area in Canada. Growing in population, the 2011 census recorded a population of 2,615,060. As of 2015, the population is now estimated at 2,826,498, making Toronto the fourth-largest city in North America based on the population within its city limits. Toronto trails only Mexico City, New York City, and Los Angeles by this measure, while it is the fifth-largest (behind also Chicago) if ranked by the size of its metropolitan area . An established global city, Toronto is an international centre of business, finance, arts, and culture, and widely recognized as one of the most multicultural and cosmopolitan cities in the world., Vancouver, officially the City of Vancouver, is a coastal seaport city on the mainland of British Columbia, Canada, and the most populous city in the province., Mount Everest, also known in Nepal as Sagarmth and in China as Chomolungma/, is earth's highest mountain. Its peak is above sea level. Mount Everest is in the Mahalangur Range. The international border between China (Tibet Autonomous Region) and Nepal runs across Everest's summit point. Its massif includes neighbouring peaks Lhotse, ; Nuptse, , and Changtse, ., Kluane National Park and Reserve are two units of Canada's national park system, located in the extreme southwestern corner of the territory of Yukon. Kluane National Park Reserve was established in 1972, covering ., The Rocky Mountains, commonly known as the Rockies, are a major mountain range in western North America. The Rocky Mountains stretch more than from the northernmost part of British Columbia, in western Canada, to New Mexico, in the southwestern United States. Within the North American Cordillera, the Rockies are somewhat distinct from the Pacific Coast Ranges and the Cascade Range and Sierra Nevada which all lie further to the west., Denali National Park and Preserve is a national park and preserve located in Interior Alaska, centered on Denali, the highest mountain in North America. The park and contiguous preserve encompasses more than 6 million acres (24,500 km). The national preserve is 1,334,200 acres (5,430 km). On December 2, 1980, a 2,146,580 acre (8,687 km) Denali Wilderness was established within the park. Denali's landscape is a mix of forest at the lowest elevations, including deciduous taiga. The preserve is also home to tundra at middle elevations, and glaciers, rock, and snow at the highest elevations. The longest glacier is the Kahiltna Glacier. Today, 400,000 people visit the park annually. Wintertime activities includes dog-sledding, cross-country skiing, and snowmachining., South America is a continent located in the western hemisphere, mostly in the southern hemisphere, with a relatively small portion in the northern hemisphere. It is also considered a subcontinent of the Americas, which is the model used in nations that speak Romance languages. The reference to South America instead of other regions (like Latin America or the Southern Cone) has increased in the last decades due to changing geopolitical dynamics (in particular, the rise of Brazil)., The Anchorage Metropolitan Statistical Area , as defined by the United States Census Bureau, is an area consisting of the Municipality of Anchorage and the Matanuska-Susitna Borough in the south central region of Alaska., Alaska is a U.S. state located in the northwest extremity of North America. The Canadian administrative divisions of British Columbia and Yukon border the state to the east; its most extreme western part is Attu Island; it has a maritime border with Russia to the west across the Bering Strait. To the north are the Chukchi and Beaufort seasthe southern parts of the Arctic Ocean. The Pacific Ocean lies to the south and southwest. Alaska is the largest state in the United States by area, the 3rd least populous and the least densely populated of the 50 United States. Approximately half of Alaska's residents (the total estimated at 738,432 by the U.S. Census Bureau in 2015) live within the Anchorage metropolitan area. Alaska's economy is dominated by the fishing, natural gas, and oil industries, resources which it has in abundance. Military bases and tourism are also a significant part of the economy., The Alaska Range is a relatively narrow, 650-km-long (400 mi) mountain range in the southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest end to the White River in Canada's Yukon Territory in the southeast. The highest mountain in North America, Denali, is in the Alaska Range. It is part of the American Cordillera., The Western Hemisphere is a geographical term for the half of the earth that lies west of the Prime meridian (which crosses Greenwich, UK) and east of the antimeridian, the other half being called the Eastern Hemisphere. , The Geological Survey of Canada (GSC) is a Canadian federal government agency responsible for performing geological surveys of the country, developing Canada's natural resources and protecting the environment. A branch of the Earth Sciences Sector of Natural Resources Canada, the GSC is the country's oldest scientific agency and was one of its first government organizations., A continent is one of several very large landmasses on Earth. Generally identified by convention rather than any strict criteria, up to seven regions are commonly regarded as continents. Ordered from largest in size to smallest, they are: Asia, Africa, North America, South America, Antarctica, Europe, and Australia. In geology, areas of continental crust include regions covered with water., The Arctic (or ) is a polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Alaska (United States), Canada, Finland, Greenland (Denmark), Iceland, Norway, Russia, and Sweden. Land within the Arctic region has seasonally varying snow and ice cover, with predominantly treeless permafrost-containing tundra. Arctic seas contain seasonal sea ice in many places., The Department of Natural Resources (French: "Ministère des Ressources naturelles"), operating under the FIP applied title Natural Resources Canada (NRCan), is the ministry of the government of Canada responsible for natural resources, energy, minerals and metals, forests, earth sciences, mapping and remote sensing. It was created in 1995 by amalgamating the now-defunct Departments of Energy, Mines and Resources and Forestry. Natural Resources Canada (NRCan) works to ensure the responsible development of Canada's natural resources, including energy, forests, minerals and metals. NRCan also uses its expertise in earth sciences to build and maintain an up-to-date knowledge base of our landmass and resources. To promote internal collaboration, NRCan has implemented a departmental wide wiki based on MediaWiki. Natural Resources Canada also collaborates with American and Mexican government scientists, along with the Commission for Environmental Cooperation, to produce the North American Environmental Atlas, which is used to depict and track environmental issues for a continental perspective., The Pacific Ocean is the largest of the Earth's oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south and is bounded by Asia and Australia in the west and the Americas in the east., Yukon (also commonly called the Yukon) is the westernmost and smallest of Canada's three federal territories (the other two are Northwest Territories and Nunavut). The territory is very sparsely populated with its about 35,000 people on almost half a million square kilometres. Whitehorse is the territorial capital and Yukon's only city., The Northern Hemisphere is the half of Earth that is north of the equator. For other planets in the Solar System, north is defined as being in the same celestial hemisphere relative to the invariable plane of the solar system as Earth's North pole.
Due to the Earth's axial tilt, winter in the Northern Hemisphere lasts from the December solstice (typically December 21 UTC) to the March Equinox (typically March 20 UTC), while summer lasts from the June solstice (typically June 21 UTC) through to the September equinox (typically September 23 UTC). The dates vary each year due to the difference between the calendar year and the astronomical year., The Bering Strait ("Beringov proliv", Yupik: "Imakpik") is a strait of the Pacific, which borders with the Arctic to north. It is located between Russia and the United States. Named after Vitus Bering, a Danish-born explorer in the service of the Russian Empire, it lies slightly south of the Arctic Circle being at about 65° 40' N latitude. The present Russia-US east-west boundary is at 168° 58' 37" W., A mountain range (also mountain barrier, belt, or system) is a geographic area containing numerous geologically related mountains. A mountain system or system of mountain ranges, sometimes is used to combine several geological features that are geographically (regionally) related. On Earth, most significant mountain ranges are the result of plate tectonics, though mountain ranges are formed by a range of processes, are found on many planetary mass objects in the Solar System and are likely a feature of most terrestrial planets., A geologist is a scientist who studies the solid and liquid matter that constitutes the Earth as well as the processes that shape it. Geologists usually study geology, although backgrounds in physics, chemistry, biology, and other sciences are also useful. Field work is an important component of geology, although many subdisciplines incorporate laboratory work., Mount Logan is the highest mountain in Canada and the second - highest peak in North America , after Denali . The mountain was named after Sir William Edmond Logan , a Canadian geologist and founder of the Geological Survey of Canada ( GSC ) . Mount Logan is located within Kluane National Park and Reserve in southwestern Yukon , less than 40 kilometres ( 25 mi ) north of the Yukon / Alaska border . Mount Logan is the source of the Hubbard and Logan Glaciers . Logan is believed to have the largest base circumference of any non-volcanic mountain on Earth ( a large number of shield volcanoes are much larger in size and mass ) , including a massif with eleven peaks over 5,000 metres ( 16,400 ft ) . Due to active tectonic uplifting , Mount Logan is still rising in height . Before 1992 , the exact elevation of Mount Logan was unknown and measurements ranged from 5,959 to 6,050 metres ( 19,551 to 19,849 ft ) . In May 1992 , a GSC expedition climbed Mount Logan and fixed the current height of 5,959 metres ( 19,551 ft ) using GPS . Temperatures are extremely low on and near Mount Logan . On the 5,000 m high plateau , air temperature hovers around  45 ° C (  49 ° F ) in the winter and reaches near freezing in summer with the median temperature for the year around  27 ° C (  17 ° F ) . Minimal snow melt leads to a significant ice cap , reaching almost 300 m ( 984 ft ) in certain spots ., The Caribbean Sea is a sea of the Atlantic Ocean in the tropics of the Western Hemisphere. It is bounded by Mexico and Central America to the west and south west, to the north by the Greater Antilles starting with Cuba, to the east by the Lesser Antilles, and to the south by the north coast of South America., Attu is the westernmost and largest island in the Near Islands group of the Aleutian Islands of Alaska, and the westernmost point of land relative to Alaska, the United States, North America and the Americas. The island became uninhabited in 2010., Winnipeg is the capital and largest city of the province of Manitoba in Canada. It is located near the longitudinal centre of North America, at the confluence of the Red and Assiniboine Rivers., The Caribbean (or ) is a region that consists of the Caribbean Sea, its islands (some surrounded by the Caribbean Sea and some bordering both the Caribbean Sea and the North Atlantic Ocean) and the surrounding coasts. The region is southeast of the Gulf of Mexico and the North American mainland, east of Central America, and north of South America., Canada (French: ) is a country in the northern half of North America. Its ten provinces and three territories extend from the Atlantic to the Pacific and northward into the Arctic Ocean, covering , making it the world's second-largest country by total area and the fourth-largest country by land area. Canada's border with the United States is the world's longest land border. The majority of the country has a cold or severely cold winter climate, but southerly areas are warm in summer. Canada is sparsely populated, the majority of its land territory being dominated by forest and tundra and the Rocky Mountains. About four-fifths of the country's population of 36 million people is urbanized and live near the southern border. Its capital is Ottawa, its largest city is Toronto; other major urban areas include Montreal, Vancouver, Calgary, Edmonton, Quebec City, Winnipeg and Hamilton., Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. It is formed when layers of decomposing plant and animal matter are exposed to intense heat and pressure under the surface of the Earth over millions of years. The energy that the plants originally obtained from the sun is stored in the form of chemical bonds in the gas., Russia (from the  Rus'), also officially known as the Russian Federation, is a country in Eurasia. At , Russia is the largest country in the world by surface area, covering more than one-eighth of the Earth's inhabited land area, and the ninth most populous, with over 140 million people at the end of March 2016. The European western part of the country is much more populated and urbanised than the eastern, about 77% of the population live in European Russia. Russia's capital Moscow is one of the largest cities in the world, other major urban centers include Saint Petersburg, Novosibirsk, Yekaterinburg, Nizhny Novgorod and Samara., The Chitina River (or ; Ahtna Athabascan Tsedi Na < "tsedi" "copper" + "na" "river") is a tributary of the Copper River in the U.S. state of Alaska. It begins in the Saint Elias Mountains at the base of Chitana Glacier and flows generally northwest through the WrangellSt. Elias National Park and Preserve to meet the larger river near Chitina. The watershed was once a major copper mining region., Geology (from the Ancient Greek , "g", i.e. "earth" and -o, "-logia", i.e. "study of, discourse") is an earth science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any terrestrial planet (such as the geology of the Moon or Mars)., A landform is a natural feature of the solid surface of the Earth or other planetary body. Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Typical landforms include hills, mountains, plateaus, canyons, valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great ocean basins., A mountain is a large landform that stretches above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges., The Arctic Ocean is the smallest and shallowest of the world's five major oceans. The International Hydrographic Organization (IHO) recognizes it as an ocean, although some oceanographers call it the Arctic Mediterranean Sea or simply the Arctic Sea, classifying it a mediterranean sea or an estuary of the Atlantic Ocean. Alternatively, the Arctic Ocean can be seen as the northernmost part of the all-encompassing World Ocean., The elevation of a geographic location is its height above or below a fixed reference point, most commonly a reference geoid, a mathematical model of the Earth's sea level as an equipotential gravitational surface (see Geodetic system, vertical datum).
Elevation, or geometric height, is mainly used when referring to points on the Earth's surface, while altitude or geopotential height is used for points above the surface, such as an aircraft in flight or a spacecraft in orbit, and depth is used for points below the surface., A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as stream, creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague., Denali (also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of above sea level. With a topographic prominence of and a topographic isolation of , Denali is the third most prominent and third most isolated peak after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U.S. state of Alaska, Denali is the centerpiece of Denali National Park and Preserve., Logan Glacier is a glacier in the U.S. state of Alaska. It heads down the northern slopes of Mount Logan in the Yukon, flowing northwest across the Canada-United States boundary to form the headwaters of the Chitina River. It was named for its nearness to Mount Logan., Mean sea level (MSL) (abbreviated simply sea level) is an average level of the surface of one or more of Earth's oceans from which heights such as elevations may be measured. MSL is a type of vertical datuma standardised geodetic reference pointthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured in order to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is the midpoint between a mean low and mean high tide at a particular location., Earth, otherwise known as the world, is the third planet from the Sun and the only object in the Universe known to harbor life. It is the densest planet in the Solar System and the largest of the four terrestrial planets., North America is a continent entirely within the Northern Hemisphere and almost all within the Western Hemisphere. It can also be considered a northern subcontinent of the Americas. It is bordered to the north by the Arctic Ocean, to the east by the Atlantic Ocean, to the west and south by the Pacific Ocean, and to the southeast by South America and the Caribbean Sea., Calgary is a city in the Canadian province of Alberta. It is situated at the confluence of the Bow River and the Elbow River in the south of the province, in an area of foothills and prairie, about east of the front ranges of the Canadian Rockies. In the 2011 census, the City of Calgary had a population of 1,096,833 and a metropolitan population of 1,214,839, making it the largest city in Alberta, and the third-largest municipality and fifth-largest census metropolitan area (CMA) in Canada., The Americas, also collectively called America, encompass the totality of the continents of North America and South America. Together they make up most of Earth's western hemisphere and comprise the "New World". , Volcanism is the phenomenon of eruption of molten rock (magma) onto the surface of the Earth or a solid-surface planet or moon, where lava, pyroclastics and volcanic gases erupt through a break in the surface called a vent. It includes all phenomena resulting from and causing magma within the crust or mantle of the body, to rise through the crust and form volcanic rocks on the surface., The Atlantic Ocean is the second largest of the world's oceans with a total area of about . It covers approximately 20 percent of the Earth's surface and about 29 percent of its water surface area. It separates the "Old World" from the "New World"., British Columbia (BC) is the westernmost province of Canada, with a population of more than four million people located between the Pacific Ocean and the Rocky Mountains. 
British Columbia is also a component of the Pacific Northwest and the Cascadia bioregion, along with the U.S. states of Idaho, Oregon, Washington and Alaska., Subject: mount logan, Relation: located_on_terrain_feature, Options: (A) alaska (B) andes (C) arctic ocean (D) asia (E) atlantic ocean (F) australia (G) british columbia (H) caribbean (I) caribbean sea (J) confluence (K) denmark (L) earth (M) england (N) eurasia (O) europe (P) lesser antilles (Q) mainland (R) manitoba (S) mediterranean sea (T) mount everest (U) north america (V) northern hemisphere (W) pacific ocean (X) russia (Y) saint elias mountains (Z) san juan province ([) sierra nevada (\) south america (]) yukon
