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) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Queen Maud Land
Queen Maud Land ( no, Dronning Maud Land) is a roughly region of Antarctica claimed by Norway as a dependent territory. It borders the claimed British Antarctic Territory 20° west and the Australian Antarctic Territory 45° east. In addition, a small unclaimed area from 1939 was annexed in June 2015. Positioned in East Antarctica, it makes out about one-fifth of the continent, and is named after the Norwegian queen Maud of Wales (1869–1938). In 1930, the Norwegian Hjalmar Riiser-Larsen was the first person known to have set foot in the territory. On 14 January 1939, the territory was claimed by Norway. On 23 June 1961, Queen Maud Land became part of the Antarctic Treaty System, making it a demilitarised zone. It is one of two Antarctic claims made by Norway, the other being Peter I Island. They are administered by the Polar Affairs Department of the Norwegian Ministry of Justice and Public Security in Oslo. Most of the territory is covered by the east Antarctic ic ...

Inaccessible Island
Inaccessible Island is a volcanic island located in the South Atlantic Ocean, south-west of Tristan da Cunha. Its highest point, Cairn Peak, reaches , and the island is in area. The volcano was last active six million years ago and is currently extinct. Inaccessible Island is part of the archipelago of Tristan da Cunha, which is part of the overseas territory of the United Kingdom known as Saint Helena, Ascension and Tristan da Cunha. Tristan da Cunha itself is accessible only by sea via a seven-day voyage from Cape Town, South Africa, and the harbour on Inaccessible Island allows access for only a few days of the year. Access to the island must be granted by the local government office. Geography The island is approximately to the southwest of the main island of the Tristan da Cunha archipelago. Mostly desolate and inhospitable, the island has few small, rocky beaches. Generations of sailors were wary of the difficult landing and inhospitable terrain. Inaccessible Isla ...

Turtle Islands, Sierra Leone
The Turtle Islands are in the Atlantic Ocean, located west of Sherbro Island in the Southern Province of Sierra Leone. Of the eight islands, seven are inhabited. Sherbro is the predominant ethnic group. This eight-island archipelagos expands in a zone of over shallow waters and white sand banks. Yele, Bakie, Bumpetuk, Chepo, Hoong, Mut, Nyangei and Sei are the names of the islands. Economic activities Fishing is the main economic activity. Coconut products and tourism may contribute to the income in a lesser extent. Traditions Turtle Islands is a remote destination and the fishing communities have preserved their faith and tradition in a vivid manner. Residents spend their evenings in groups. Sherbros are very social, spending time together drinking and singing traditional songs focused on bravery and romance. One of the eight islands, Hoong, is off limits to visitors or women.

Western Sahara
Western Sahara ( '; ; ) is a disputed territory on the northwest coast and in the Maghreb region of North and West Africa. About 20% of the territory is controlled by the self-proclaimed Sahrawi Arab Democratic Republic (SADR), while the remaining 80% of the territory is occupied and administered by neighboring Morocco. Its surface area amounts to . It is one of the most sparsely populated territories in the world, mainly consisting of desert flatlands. The population is estimated at just over 500,000, of which nearly 40% live in Laayoune, the largest city in Western Sahara. Occupied by Spain until 1975, Western Sahara has been on the United Nations list of non-self-governing territories since 1963 after a Moroccan demand. It is the most populous territory on that list, and by far the largest in area. In 1965, the United Nations General Assembly adopted its first resolution on Western Sahara, asking Spain to decolonize the territory. One year later, a new resolution was ...

Great Circle
In mathematics, a great circle or orthodrome is the circular intersection of a sphere and a plane passing through the sphere's center point. Any arc of a great circle is a geodesic of the sphere, so that great circles in spherical geometry are the natural analog of straight lines in Euclidean space. For any pair of distinct non- antipodal points on the sphere, there is a unique great circle passing through both. (Every great circle through any point also passes through its antipodal point, so there are infinitely many great circles through two antipodal points.) The shorter of the two great-circle arcs between two distinct points on the sphere is called the ''minor arc'', and is the shortest surface-path between them. Its arc length is the great-circle distance between the points (the intrinsic distance on a sphere), and is proportional to the measure of the central angle formed by the two points and the center of the sphere. A great circle is the largest circle that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Longitude
Longitude (, ) is a geographic coordinate that specifies the east– west position of a point on the surface of the Earth, or another celestial body. It is an angular measurement, usually expressed in degrees and denoted by the Greek letter lambda (λ). Meridians are semicircular lines running from pole to pole that connect points with the same longitude. The prime meridian defines 0° longitude; by convention the International Reference Meridian for the Earth passes near the Royal Observatory in Greenwich, England on the island of Great Britain. Positive longitudes are east of the prime meridian, and negative ones are west. Because of the Earth's rotation, there is a close connection between longitude and time measurement. Scientifically precise local time varies with longitude: a difference of 15° longitude corresponds to a one-hour difference in local time, due to the differing position in relation to the Sun. Comparing local time to an absolute measure of ti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Pole
The South Pole, also known as the Geographic South Pole, Terrestrial South Pole or 90th Parallel South, is one of the two points where Earth's axis of rotation intersects its surface. It is the southernmost point on Earth and lies antipodally on the opposite side of Earth from the North Pole, at a distance of 12,430 miles (20,004 km) in all directions. Situated on the continent of Antarctica, it is the site of the United States Amundsen–Scott South Pole Station, which was established in 1956 and has been permanently staffed since that year. The Geographic South Pole is distinct from the South Magnetic Pole, the position of which is defined based on Earth's magnetic field. The South Pole is at the centre of the Southern Hemisphere. Geography For most purposes, the Geographic South Pole is defined as the southern point of the two points where Earth's axis of rotation intersects its surface (the other being the Geographic North Pole). However, Earth's axis of rota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
