Bir Tawil
( arz, بير طويل, translit=Bīr Ṭawīl, lit=tall water well, ) is a area of land along the border between Egypt and Sudan, which is uninhabited and claimed by neither country. When spoken of in association with the neighbouring Halaib Triangle, it is sometimes referred to as the Triangle, despite the area's quadrilateral shape; the two "triangles" border at a quadripoint. Its ' status results from a discrepancy between the straight political boundary between Egypt and Sudan established in 1899, and the irregular administrative boundary established in 1902. Egypt asserts the political boundary, and Sudan asserts the administrative boundary, with the result that the Triangle is claimed by both and by neither. In 2014, author Alastair Bonnett described as the only place on Earth that was habitable but was not claimed by any recognised government. History On 19 January 1899, an agreement between the United Kingdom and Egypt relating to the administration of Sudan def ...

Terra Nullius
''Terra nullius'' (, plural ''terrae nullius'') is a Latin expression meaning " nobody's land". It was a principle sometimes used in international law to justify claims that territory may be acquired by a state's occupation of it. : : : : : : There are currently three territories claimed to be ''terra nullius'', two of which caused by border disputes between sovereign states, and one caused by no sovereign state claiming the land. Doctrine In international law, ''terra nullius'' is territory which belongs to no state. Sovereignty over territory which is ''terra nullius'' can be acquired by any state by occupation. According to Oppenheimer, “‘The only territory which can be the object of occupation is that which does not already belong to another state, whether it is uninhabited, or inhabited by persons whose community is not considered to be a state; for individuals may live on as territory without forming themselves into a state proper exercising sovereignt ...

Map Of The Hala'ib Triangle And Bir Tawil In 1912
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Micronation
A micronation is a political entity whose members claim that they belong to an independent nation or sovereign state, but which lacks legal recognition by world governments or major international organizations. Micronations are classified separately from de facto states and quasi-states; they are also not considered to be autonomous nor self-governing as they lack the legal basis in international law for their existence. Micronations' activities are almost always trivial enough to be ignored rather than challenged by the established nations whose territory they claim—referred to in micronationalism as "macronations." Several micronations have issued coins, flags, postage stamps, passports, medals and other state-related items, some as a source of revenue. Motivations for the creation of micronations include theoretical experimentation, political protest, artistic expression, personal entertainment and the conduct of criminal activity. The study of micronationalism is known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Land Claim
A land claim is defined as "the pursuit of recognized territorial ownership by a group or individual". The phrase is usually only used with respect to disputed or unresolved land claims. Some types of land claims include aboriginal land claims, Antarctic land claims, and post-colonial land claims. Land claims is sometimes used as a term when referring to disputed territories like Western Sahara or to refer to the claims of displaced persons. In the colonial times of the United States American men could claim a piece of land for themselves and the claim has different level of merit according to the de facto conditions: # claim without any action on the ground # claim with (movable) property of the claimant on the ground # claim with the claimant visiting the land # claim with claimant living on the land. Today, only small areas of unclaimed land remain, yet large plots of land with little economical value (e.g., in Alaska) can still be bought for very low prices. Also, in certai ...

De Jure
In law and government, ''de jure'' ( ; , "by law") describes practices that are legally recognized, regardless of whether the practice exists in reality. In contrast, ("in fact") describes situations that exist in reality, even if not legally recognized. Examples Between 1805 and 1914, the ruling dynasty of Egypt were subject to the rulers of the Ottoman Empire, but acted as de facto independent rulers who maintained a polite fiction of Ottoman suzerainty. However, starting from around 1882, the rulers had only de jure rule over Egypt, as it had by then become a British puppet state. Thus, by Ottoman law, Egypt was de jure a province of the Ottoman Empire, but de facto was part of the British Empire. In U.S. law, particularly after ''Brown v. Board of Education'' (1954), the difference between de facto segregation (segregation that existed because of the voluntary associations and neighborhoods) and de jure segregation (segregation that existed because of local laws that m ...

Diurnal Temperature Variation
In meteorology, diurnal temperature variation is the variation between a high air temperature and a low temperature that occurs during the same day. Temperature lag Temperature lag is an important factor in diurnal temperature variation: peak daily temperature generally occurs ''after'' noon, as air keeps net absorbing heat even after noon, and similarly minimum daily temperature generally occurs substantially after midnight, indeed occurring during early morning in the hour around dawn, since heat is lost all night long. The analogous annual phenomenon is seasonal lag. As solar energy strikes the Earth's surface each morning, a shallow layer of air directly above the ground is heated by conduction. Heat exchange between this shallow layer of warm air and the cooler air above is very inefficient. On a warm summer's day, for example, air temperatures may vary by from just above the ground to waist height. Incoming solar radiation exceeds outgoing heat energy for many hours afte ...

Hot Desert Climate
The desert climate or arid climate (in the Köppen climate classification ''BWh'' and ''BWk''), is a dry climate sub-type in which there is a severe excess of evaporation over precipitation. The typically bald, rocky, or sandy surfaces in desert climates are dry and hold little moisture, quickly evaporating the already little rainfall they receive. Covering 14.2% of earth's land area, hot deserts are the second most common type of climate on earth after the polar climate. There are two variations of a desert climate according to the Köppen climate classification: a hot desert climate (''BWh''), and a cold desert climate (''BWk''). To delineate "hot desert climates" from "cold desert climates", there are three widely used isotherms: most commonly a mean annual temperature of , or sometimes the coldest month's mean temperature of , so that a location with a ''BW'' type climate with the appropriate temperature above whichever isotherm is being used is classified as "hot arid sub ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wadi
Wadi ( ar, وَادِي, wādī), alternatively ''wād'' ( ar, وَاد), North African Arabic Oued, is the Arabic term traditionally referring to a valley. In some instances, it may refer to a wet (ephemeral) riverbed that contains water only when heavy rain occurs. Etymology The term ' is very widely found in Arabic toponyms. Some Spanish toponyms are derived from Andalusian Arabic where ' was used to mean a permanent river, for example: Guadalcanal from ''wādī al-qanāl'' ( ar, وَادِي الْقَنَال, "river of refreshment stalls"), Guadalajara from ''wādī al-ḥijārah'' ( ar, وَادِي الْحِجَارَة, "river of stones"), or Guadalquivir, from ''al-wādī al-kabīr'' ( ar, اَلْوَادِي الْكَبِير, "the great river"). General morphology and processes Wadis are located on gently sloping, nearly flat parts of deserts; commonly they begin on the distal portions of alluvial fans and extend to inland sabkhas or dry lakes.

Gabal Hagar El Zarqa
Gabal Hagar El Zarqa ( ar, جَـبَـل حَـجَـر الـزَّرْقَـاء, Jabal Ḥajar az-Zarqā’) is the highest point in Bir Tawil, an unclaimed area in the Nubian desert between Egypt and Sudan in Northeast Africa. Due to a long-standing disagreement over the location of that border, its jurisdiction is unclear; it is said by the National Geospatial-Intelligence Agency to be in Egypt. In December 2017 British mountaineer Ginge Fullen accompanied by a local guide summited a point to the east of the waypoint listed on the right, recording a height of at N21 53'01 E33 58'13. See also * Al Hajar Mountains * North Africa * Wildlife of Egypt * Wildlife of Sudan The wildlife of Sudan is composed of its flora and fauna.

Satellite Image Of Bir Tawil
A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which is small CubeSats. Similar satellites can work together as a group, forming constellations. Because of the high launch cost to space, satellites are designed to be as lightweight and robust as possible. Most communication satellites are radio relay stations in orbit and carry dozens of transponders, each with a bandwidth of tens of megahertz. Satellites are placed from the surface to orbit by launch vehicles, high enough to avoid orbital decay by the atmosphere. Satellites can then change or maintain the orbit by propulsion, ...

Khartoum
Khartoum or Khartum ( ; ar, الخرطوم, Al-Khurṭūm, din, Kaartuɔ̈m) is the capital of Sudan. With a population of 5,274,321, its metropolitan area is the largest in Sudan. It is located at the confluence of the White Nile, flowing north from Lake Victoria, and the Blue Nile, flowing west from Lake Tana in Ethiopia. The place where the two Niles meet is known as ''al-Mogran'' or ''al-Muqran'' (; English: "The Confluence"). From there, the Nile continues north towards Egypt and the Mediterranean Sea. Divided by these two parts of the Nile, Khartoum is a tripartite metropolis with an estimated population of over five million people, consisting of Khartoum proper, and linked by bridges to Khartoum North ( ) and Omdurman ( ) to the west. Khartoum was founded in 1821 as part of Egypt, north of the ancient city of Soba. While the United Kingdom exerted power over Egypt, it left administration of the Sudan to it until Mahdist forces took over Khartoum. The British atte ...
