• The southernmost point of (liquid) water is a bay on the Filchner–Ronne Ice Shelf along the coast of Antarctica (83°S 59°W / 83°S 59°W / -83; -59)^{[citation needed]}, about 100 km (60 mi) south of Berkner Island.
  • The southernmost point of ocean is located on the Gould Coast (84°30′S 150°0′W / 84.500°S 150.000°W / -84.500; -150.000 (southernmost point of ocean)).^{[citation needed][1]}
  • The southernmost point of
    open ocean is in the Bay of Whales, also part of the Ross Sea, at 78°30'S, at the edge of the Ross Ice Shelf.^[2]
    • The southernmost island is considered to be Deverall Island, near the Shackleton Coast, surrounded by the Ross Ice Shelf although there is an island in Lake Vostok but it is currently under ice. ^[3]

Easternmost and westernmost

• The easternmost and westernmost points on Earth, based on the east–west standard for describing longitude, can be found anywhere along the 180th meridian, which passes through the Arctic, Pacific, and Southern Oceans, as well as parts of Siberia (including Wrangel Island), Antarctica, and three islands of Fiji (Vanua Levu's eastern peninsula, the middle of Taveuni, and the western part of Rabi Island).
  • Using instead the path of the International Date Line (which is not a straight line), the westernmost point on land is Attu Island, Alaska, and the easternmost point on land is Caroline Island, Kiribati.^[a]

• The meridian that crosses the greatest total distance on land (disregarding intervening bodies of water) is still to be determined. It is likely located in the vicinity of 22°E, which is the longest integer meridian that fits that criterion, crossing a total of 13,035 km (8,100 mi) of land through Europe (3,370 km or 2,090 mi), Africa (7,458 km or 4,634 mi), and Antarctica (2,207 km or 1,371 mi).[b] More than 65% of this meridian's length is located on land. The next six longest integer meridians by total distance over land are, in order:
  • 23°E: 12,953 km (8,049 mi) through Europe (3,325 km or 2,066 mi), Africa (7,415 km or 4,607 mi), and Antarctica (2,214 km or 1,376 mi)

Along any geodesic

These are the longest straight lines^[c] that can be drawn between any two points on the surface of the Earth and remain exclusively over land or water; the points need not lie on the same line of latitude or longitude.

• The longest continuous straight-line (great circle) path over land is 13,588 km (8,443 mi) long and spans between the West African coast near Greenville, Liberia (5°2′51.59″N 9°7′23.26″W / 5.0476639°N 9.1231278°W / 5.0476639; -9.1231278) and a peninsula about 100 km (60 mi) northeast of Wenzhou, China (28°17′7.68″N 121°38′17.31″E / 28.2854667°N 121.6381417°E / 28.2854667; 121.6381417), passing over the Suez Canal.^[4]
  • The longest continuous straight-line land distance solely within continental
    Port Elizabeth, South Africa. This line passes through Morocco, Algeria, Mali, Niger, Nigeria, Cameroon, Equatorial Guinea, Gabon, Republic of the Congo, Democratic Republic of the Congo, Angola, Namibia, Botswana, and South Africa.^{[citation needed}
    ]
  • The longest continuous straight-line land distance solely within continental Asia is 10,152 km (6,308 mi), along a line that begins on the Indian coast near Kanyakumari and ends at the Bering Sea coast of the Chukchi Peninsula in Russia. This line passes through India, Nepal, China, Mongolia, and Russia.^{[citation needed]}
  • The longest continuous straight-line land distance solely within continental Europe (defining the Ural Mountains as the border between Europe and Asia) is 5,325 km (3,309 mi), along a line that begins at Cape St. Vincent, Portugal, and ends at the Urals, near the town of Perm, Russia. This line passes through Portugal, Spain, France, Germany, Poland, Lithuania, Belarus, and Russia.^{[citation needed]}
  • The longest continuous straight-line land distance solely within continental North America is 7,602 km (4,724 mi), along a line that begins at Point Hope, Alaska, United States, and ends 34 km (21 mi) southwest of the town of Salina Cruz, Mexico. This line passes through Alaska, Canada, the contiguous United States, and Mexico.^{[citation needed]}
  • The longest continuous straight-line land distance solely within continental South America is 7,248 km (4,504 mi), along a line that begins 10 km (6.2 mi) northeast of Puerto Cumarebo, Venezuela, and ends 80 km (50 mi) south of the town of Punta Arenas, Chile.

• There are several possible candidates for the longest continuous straight-line distance in any direction at sea, as there are many possible ways to travel along a great circle for more than the antipodic length of 19,840 km (12,330 mi). Some examples of such routes would be:
  • From the south coast of
    Kamchatka, near Ossora (59°38′N 163°24′E / 59.633°N 163.400°E / 59.633; 163.400). This route is 32,040 km (19,910 mi) long.^[5] This route was confirmed to be the longest (at about 32,090 km or 19,940 mi) given map data at a 1.8 km (1.1 mi) level of resolution.^[6][7][d]
  • From the south coast of
    Ciudad Lázaro Cárdenas (17°57′N 101°57′W / 17.950°N 101.950°W / 17.950; -101.950). This route is 25,267 km (15,700 mi) long.^[8]
  • From Invercargill, New Zealand (46°37′S 168°59′E / 46.617°S 168.983°E / -46.617; 168.983) across Cape Horn, then off the coast of Brazil close to Recife, passing north of Cape Verde, passing the antipodal point and ending somewhere on the southwest coast of Ireland (52°09′N 6°34′W / 52.150°N 6.567°W / 52.150; -6.567). This route is 20,701 km (12,863 mi) long.^[9]

Along any diameter (straight line passing through the centre of the Earth)

As distinct from geodesic lines, which appear straight only when projected onto the spheroidal surface of the Earth (i.e. arcs of great circles), straight lines passing through the Earth's centre can be constructed through the interior of the Earth between almost any two points on the surface of the Earth (some extreme topographical situations such as overhanging cliffs being the rare exceptions^{[citation needed]}). A line projected from the summit of Cayambe in Ecuador (see highest points) through the axial centre of the Earth to its antipode on the island of Sumatra results in the longest diameter that can be produced anywhere through the Earth. As the variable circumference of the Earth approaches 40,000 kilometres (25,000 mi), such a maximum "diameter" or "antipodal" line would be on the order of 13,000 kilometres (8,000 mi) long.^{[citation needed]}

Elevation

Highest points

• The highest point on Earth's surface measured from sea level is the summit of Mount Everest, on the border of Nepal and China. While measurements of its height vary slightly, the elevation of its peak was most recently established in 2020 by the Nepali and Chinese authorities as 8,848.86 m (29,031.7 ft) above sea level.^[10] The summit was first reached probably by Sir Edmund Hillary of New Zealand and Tenzing Norgay Sherpa of Nepal in 1953.
• The point farthest from Earth's centre is the summit of
  Chimborazo^[11] in Ecuador, at 6,384.4 km (3,967.1 mi) from Earth's centre; the peak's elevation relative to sea level is 6,263.47 m (20,549 ft).^[e] Because Earth is an oblate spheroid rather than a perfect sphere, it is wider at the equator and narrower toward each pole. Therefore, the summit of Chimborazo, which is near the Equator, is farther away from Earth's centre than the summit of Mount Everest is; the latter is 2,168 m (7,112.9 ft) closer, at 6,382.3 km (3,965.8 mi) from Earth's centre. Peru's Huascarán
  (at 6,384.4 m or 20,946 ft) contends closely with Chimborazo, though the former is a mere 10 m (33 ft) closer to the Earth's centre.
• The fastest point on Earth or, in other words, the point farthest from Earth's rotational axis is the summit of
  figure of Earth
  . More important, however, Cayambe's proximity to the Equator means that the majority of its distance from the Earth's centre contributes to Cayambe's distance from the Earth's axis.

• The highest volcano is Ojos del Salado on the Argentina–Chile border. It has the highest summit, 6,893 m (22,615 ft), of any volcano on Earth.
• The highest natural lake is an unnamed crater lake on Ojos del Salado at 6,390 m (20,965 ft),^[14] on the Argentina side. Another candidate was Lhagba Pool on the northeast slopes of Mount Everest, Tibet, at an elevation of 6,368 m (20,892 ft), which has since dried up.^[15]
• The highest navigable lake is Lake Titicaca, on the border of Bolivia and Peru in the Andes, at 3,812 m (12,507 ft).
• The highest glacier is the Khumbu Glacier on the southwest slopes of Mount Everest in Nepal, beginning on the west side of Lhotse at an elevation of 7,600 to 8,000 m (24,900 to 26,200 ft).^[16]
• The highest river is disputed; one candidate from many possibilities is the Ating Ho, which flows into the Aong Tso (Hagung Tso), a large lake in Tibet, and has an elevation of about 6,100 m (20,013 ft) at its source at 32°49′30″N 81°03′45″E / 32.82500°N 81.06250°E / 32.82500; 81.06250 (Ating Ho (source)). Another very large and high river is the Yarlung Tsangpo or upper Brahmaputra River in Tibet, whose main stem, the Maquan River, has its source at about 6,020 m (19,751 ft) above sea level at 30°48′59″N 82°42′45″E / 30.81639°N 82.71250°E / 30.81639; 82.71250 (Maquan River (source)).^[17] Above these elevations, there are no constantly flowing rivers since the temperature is almost always below freezing.
• The highest island is one of a number of islands in the Orba Co lake in Tibet, at an elevation of 5,209 m (17,090 ft).^[18]

Highest points attainable by transportation

• The highest point accessible
  • by land vehicle is an elevation of 6,688 m (21,942 ft) on
    Suzuki Samurai
    , setting the high-altitude record for a four-wheeled vehicle.
  • by road (dead end) is on a mining road to the summit of Aucanquilcha in Chile, which reaches an elevation of 6,176 m (20,262 ft). It was once usable by 20-tonne mining trucks.^[19] The road is no longer usable. 21°12′50″S 68°28′30″W / 21.214°S 68.475°W / -21.214; -68.475
  • by road (mountain pass) is disputed; there are a number of competing claims for this title due to the definition of "motorable pass" (i.e. a surfaced road or one simply passable by a vehicle):
    • The highest asphalted road is the single-lane road to Umling La, located 17 km (11 mi) west of Demchok in Ladakh, India, which reaches 5,800 m (19,029 ft) ("19,300 feet" according to a Border Roads Organisation sign there that recognizes it as the "World's Highest Motorable Pass").^[20][21] Before the asphalting of the road over Umling La, the highest asphalted road was Tibet's Semo La pass at 5,565 m (18,258 ft). It is used by trucks and buses regularly.^[22] The Ticlio pass, on the Central Road of Peru, is the highest surfaced road in the Americas, at an elevation of 4,818 m (15,807 ft).
    • The highest unsurfaced road has several different claimants. All are unsurfaced or gravel roads including Mana Pass, between India and Tibet, which is crossed by a gravel road reaching 5,610 m (18,406 ft). The heavily trafficked Khardung La in Ladakh lies at 5,359 m (17,582 ft). A possibly motorable gravel road crosses Marsimik La in Ladakh at 5,582 m (18,314 ft).
  • by train is
    Qinghai–Tibet (Qingzang) Railway in the Tanggula Mountains of Qinghai/Tibet, China, at 5,072 m (16,640 ft). The Tanggula railway station is the world's highest railway station at 5,068 m (16,627 ft). Before the Qingzang Railway was built, the highest railway ran between Lima and Huancayo in Peru, reaching 4,829 m (15,843 ft) at Ticlio.^[23]
  • by oceangoing vessel is a segment of the Rhine–Main–Danube Canal between the Hilpoltstein and Bachhausen locks in Bavaria, Germany. The locks artificially raise the surface level of the water in the canal to 406 m (1,332 ft) above mean sea level, higher than any other lock system in the world, making it the highest point currently accessible by oceangoing commercial watercraft.

• The highest commercial airport is Daocheng Yading Airport, Sichuan, China, at 4,411 m (14,472 ft).^[24] The proposed Nagqu Dagring Airport in Tibet, if built, will be 25 m (82 ft) higher at 4,436 m (14,554 ft).
• The highest helipad is Sonam, Siachen Glacier, India, at a height of 6,400 m (20,997 ft) above sea level.^[25]
• The highest permanent human settlement is La Rinconada, Peru, 5,100 m (16,732 ft), in the Peruvian Andes.
• The farthest road from the Earth's centre is the Road to Carrel Hut in the Ecuadorian Andes, at an elevation of 4,850 m (15,912 ft) above sea level and a distance of 6,382.9 km (3,966 mi) from the centre of the Earth.^[26]

Lowest points

Lowest natural points

• The deepest point below the ocean's atmospheric surface is
  Trieste, followed by filmmaker James Cameron in 2012 aboard Deepsea Challenger. Between 2020 and 2022, DSV Limiting Factor made 19 dives to Challenger Deep, carrying with it 19 further visitors.^[28][29]
• The lowest point underground is in the Veryovkina Cave in Georgia, where the altitude difference between the cave's entrance and the deepest explored point (the maximum depth) is 2,212 meters (7,257 ft), reached in 2019 by a Perovo-speleo team.^[30]
• The lowest point on land not covered by liquid water is the canyon under Denman Glacier in Antarctica, with the bedrock being 3,500 m (11,500 ft) below sea level.^[31][32]

• The lowest point on dry land is the shore of the Dead Sea, shared by Israel and Jordan, 432.65 m (1,419 ft) below sea level. As the Dead Sea waters are receding, the water surface level drops more than 1 metre (3.3 ft) per year.^[33]
• The point on the atmospheric surface closest to the Earth's centre (interpreted as a natural surface of the land or sea that is accessible by a person) is the surface of the Arctic Ocean at the Geographic North Pole (6,356.77 km or 3,950 mi).
  • The point on the surface of Earth's crust closest to the Earth's centre (interpreted as a land surface or sea floor) is the bottom of Litke Deep, in the Arctic Ocean, at 6,351.7043 km (3,947 mi) from Earth's centre; the deep's depth relative to sea level is 5,449 m (17,877 ft). Because Earth is an oblate spheroid rather than a perfect sphere, it is wider at the equator and narrower toward each pole. Therefore, the bottom of Litke Deep, which is near the North Pole, is closer to Earth's centre than the bottom of Challenger Deep is; the latter is 14.7268 km (48,316.3 ft) further, at 6,366.4311 km (3,955.9 mi) from Earth's centre.^[34] Molloy Deep, also in Arctic Ocean (at 6,357.5178 km or 3,950 mi) from Earth's centre contends closely with Litke Deep, the difference from Earth's centre being just 389 m (1,276 ft).
  • The point on the ocean surface farthest below sea level is located in the
    global mean sea level.^[35]

• The lowest point underground ever reached was 12,262 m (40,230 ft) deep (SG-3 at the Kola Superdeep Borehole, which has since been enclosed).
• The lowest human-sized point underground is 3,900 m (12,800 ft)^[36] below ground at the TauTona Mine, Carletonville, South Africa.
• The lowest (from sea level) artificially made point with open sky may be the Hambach surface mine, Germany, which reaches a depth of 293 m (961 ft) below sea level.
• The lowest (from surface) artificially made point with open sky may be the
  Bingham Canyon Open Pit Copper Mine, Utah
  , United States, at a depth of 1,200 m (3,900 ft) below surface level.
• The lowest point underwater is the 10,685 m (35,056 ft)-deep (as measured from the
  subsea wellhead) oil and gas well drilled on the Tiber Oil Field in the Gulf of Mexico. The wellhead of this well is an additional 1,259 m (4,131 ft) underwater, for a total distance of 11,944 m (39,186 ft) as measured from sea level.^[37]28°44′12″N 88°23′13″W / 28.736667°N 88.386944°W / 28.736667; -88.386944

• The lowest point accessible:
  • by road, excluding roads in mines, is any of the roads alongside the Dead Sea in Israel and Jordan, which are the lowest on Earth at 418 m (1,371 ft) below sea level.
    • The lowest undersea highway tunnel is the Ryfast tunnel in Norway, at 292 m (958 ft) below sea level.

• The most distant point from an ocean is the Eurasian Pole of Inaccessibility (or "EPIA") 46°17′N 86°40′E / 46.283°N 86.667°E / 46.283; 86.667 (Continental Pole of Inaccessibility), in
  Dzoosotoyn Elisen Desert, is 2,645 km (1,644 mi) from the nearest coastline. The nearest settlement to the EPIA is Suluk at 46°15′N 86°50′E / 46.250°N 86.833°E / 46.250; 86.833 (Suluk), about 11 km (7 mi) to the east.^{[citation needed]} A 2007 study suggests that the historical calculation of the EPIA failed to recognize the point where the Gulf of Ob
  joins the Arctic Ocean, and proposes instead that varying definitions of coastline could result in other locations for the EPIA:
  • EPIA1, somewhere between 44°17′N 82°11′E / 44.283°N 82.183°E / 44.283; 82.183 (EPIA1.1) and 44°29′N 82°19′E / 44.483°N 82.317°E / 44.483; 82.317 (EPIA1.2), is about 2,510 ± 10 km (1,559.6 ± 6.2 mi) from the nearest ocean.
  • EPIA2, somewhere between 45°17′N 88°08′E / 45.283°N 88.133°E / 45.283; 88.133 (EPIA2.1) and 45°28′N 88°14′E / 45.467°N 88.233°E / 45.467; 88.233 (EPIA2.2), is about 2,514 ± 7 km (1,562.1 ± 4.3 mi) from the nearest ocean.^[69]

If adopted, this would place the final EPIA roughly 130 km (80 mi) closer to the ocean than the point that is currently agreed upon.

Centre

Since the Earth is a

• The centre of the standard geographic model as viewed on a traditional world map is the point 0°, 0° (the
  coordinates of zero degrees latitude by zero degrees longitude), which is located in the Atlantic Ocean about 614 km (382 mi) south of Accra, Ghana, in the Gulf of Guinea. It lies at the intersection of the Equator and the Prime Meridian, is marked with a buoy and sometimes called Null Island
  . However, the selection of the Prime Meridian as the 0° longitude meridian depended on cultural and historical factors and is therefore geographically arbitrary (any of the Earth's meridians could, in principle, be defined as 0° longitude); consequently, the position of the "Null Island" centrepoint is also arbitrary.
• The
  centre of population, the place to which there is the shortest average route for every individual human being in the world, could also be considered a "centre of the world". This point is located in the north of the Indian subcontinent
  , although the precise location has never been calculated and is constantly shifting due to changes in the distribution of the human population across the planet.

Temperatures measured directly on the ground may exceed air temperatures by 30 to 50 °C.^[104] A ground temperature of 84 °C (183.2 °F) has been recorded in Port Sudan, Sudan.^[105] A ground temperature of 93.9 °C (201 °F) was recorded in Furnace Creek, Death Valley, California, United States on 15 July 1972; this may be the highest natural ground surface temperature ever recorded.^[106] The theoretical maximum possible ground surface temperature has been estimated to be between 90 and 100 °C for dry, darkish soils of low thermal conductivity.^[107]

Satellite measurements of ground temperature taken between 2003 and 2009, taken with the

Satellite measurements of the surface temperature of Antarctica, taken between 1982 and 2013, found a coldest temperature of −93.2 °C (−136 °F) on 10 August 2010, at 81°48′S 59°18′E / 81.8°S 59.3°E / -81.8; 59.3. Although this is not comparable to an air temperature, it is believed that the air temperature at this location would have been lower than the official record lowest air temperature of −89.2 °C.^[108][109]
