Prime Meridian
A prime meridian is an arbitrary meridian (a line of longitude) in a geographic coordinate system at which longitude is defined to be 0°. Together, a prime meridian and its anti-meridian (the 180th meridian in a 360°-system) form a great circle. This great circle divides a spheroid, like the Earth, into two hemispheres: the Eastern Hemisphere and the Western Hemisphere (for an east-west notational system). For Earth's prime meridian, various conventions have been used or advocated in different regions throughout history. The Earth's current international standard prime meridian is the IERS Reference Meridian. It is derived, but differs slightly, from the Greenwich Meridian, the previous standard. A prime meridian for a planetary body not tidally locked (or at least not in synchronous rotation) is entirely arbitrary, unlike an equator, which is determined by the axis of rotation. However, for celestial objects that are tidally locked (more specifically, synchronous), th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bering Sea
The Bering Sea (, ; rus, Бе́рингово мо́ре, r=Béringovo móre) is a marginal sea of the Northern Pacific Ocean. It forms, along with the Bering Strait, the divide between the two largest landmasses on Earth: Eurasia and The Americas. It comprises a deep water basin, which then rises through a narrow slope into the shallower water above the continental shelf, continental shelves. The Bering Sea is named for Vitus Bering, a Denmark, Danish navigator in Russian service, who, in 1728, was the first European to systematically explore it, sailing from the Pacific Ocean northward to the Arctic Ocean. The Bering Sea is separated from the Gulf of Alaska by the Alaska Peninsula. It covers over and is bordered on the east and northeast by Alaska, on the west by the Russian Far East and the Kamchatka Peninsula, on the south by the Alaska Peninsula and the Aleutian Islands and on the far north by the Bering Strait, which connects the Bering Sea to the Arctic Ocean's Chukchi ...

Ross Dependency
The Ross Dependency is a region of Antarctica defined by a sector originating at the South Pole, passing along longitudes 160° east to 150° west, and terminating at latitude 60° south. It is claimed by New Zealand, a claim accepted only by the other six countries with territorial claims in Antarctica. Under the 1961 Antarctic Treaty, of which all territorial claimants are signatories, including New Zealand, all claims are held in abeyance. Article IV states: "No acts or activities taking place while the present Treaty is in force shall constitute a basis for asserting, supporting or denying a claim to territorial sovereignty in Antarctica or create any rights of sovereignty in Antarctica". The Dependency takes its name from Sir James Clark Ross, who discovered the Ross Sea, and includes part of Victoria Land, and most of the Ross Ice Shelf. Ross, Balleny, Scott and Roosevelt Islands also form part of the Dependency. History of claim Following his discovery of Victo ...

ʻEua
Eua is an island in the kingdom of Tonga. It is close to Tongatapu, but forms a separate administrative division. It has an area of , and a population in 2021 of 4,903 people. Geography Eua is a hilly island, the highest peaks are the ''Teemoa'' (chicken manure) 312 m, and the ''Vaiangina'' (watersprings) 305 m. The island is not volcanic, but was shaped by the rubbing of the Tonga Plate against the Pacific Plate, pushing Eua up and leaving the Tonga Trench on the bottom of the ocean, a short distance towards the east. The soil of Eua is volcanic, as is that of Tongatapu, but only the top layer, deposited by eruptions of nearby volcanoes ten thousands years ago. Under it are the solid rocks of pushed-up coral. Eua counts many huge caves and holes, not all of which have yet been explored. Eua and Niuatoputapu are the only islands in Tonga that have streams, and ʿEua had the only bridge in the kingdom until Vavau also built one. The stream drains into the harbour n ...

Tongatapu
Tongatapu is the main island of Tonga and the site of its capital, Nukualofa. It is located in Tonga's southern island group, to which it gives its name, and is the country's most populous island, with 74,611 residents (2016), 70.5% of the national population, on . Based on Google Earth Pro, its maximum elevation is at least above sea level along Liku Road at 21 degrees 15 minutes and 55.7 seconds south 175 degrees 08 minutes 06.4 seconds west, but could be even higher somewhere else. Tongatapu is Tonga's centre of government and the seat of its monarchy. Tongatapu has experienced more rapid economic development than the other islands of Tonga, and has thus attracted many internal migrants from them. Geography The island is (or including neighbouring islands) and rather flat, as it is built of coral limestone. The island is covered with thick fertile soil consisting of volcanic ash from neighbouring volcanoes. At the steep coast of the south, heights reach an average of , a ...

Tofua
Tofua is a volcanic island in Tonga. Located in the Haʻapai island group, it is a steep-sided composite cone with a summit caldera. It is part of the highly active Kermadec-Tonga subduction zone and its associated volcanic arc, which extends from New Zealand north-northeast to Fiji, and is formed by the subduction of the Pacific Plate under the Indo-Australian Plate. It lies about above a very active seismic zone.Ewart, A.; Bryan, W.B.; and Gill, J.B. "Mineralogy and Geochemistry of the Younger Volcanic Islands of Tonga, S.W. Pacific." ''Journal of Petrology.'' 14:3 (1973). It is connected to the nearby island of Kao by a submarine ridge. The island is a national park. Geography and geology The island is oval, measuring approximately 80 square kilometers. Its sides rise steeply to the rim of the caldera, which is partially filled by a volcanic crater lake with a depth of . The caldera was formed by a major eruption around 1,000 years BP, which left deposits up to thick on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kao (island)
Kao is an island and stratovolcano in the Haʻapai island group of Tonga. It lies about north of Tofua island and reaches above sea level, the highest point in Tonga. The date of its last eruption is unknown. Although Kao does not display fresh-looking lava flows, it is likely very recent in origin due to the absence of deep gullies or high sea cliffs. The slopes of the island rise at angles exceeding 35 degrees to the summit, which has a series of small volcanic craters. The last reported eruption was on July 10, 1847. The best access to Kao is by small boat on the south coast of the island, although heavy swell can make this treacherous and a skilled boat coxswain is required. There are no permanent paths to the summit. Small areas on the lower slopes are cultivated by kava growers. The island is densely jungled on its lower flanks, interspersed with thick chest-height ferns that are virtually impassable to all but the most determined trekkers armed with machetes and a good ...

Alaska
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with ...
