Afroeurasia
Afro-Eurasia (also Afroeurasia, Eurafrasia or the Old World) is a landmass comprising the continents of Africa, Asia, and Europe. The terms are compound words of the names of its constituent parts. Its mainland is the largest and most populous contiguous landmass on Earth. Afro-Eurasia encompasses , 57% of the world's land area, and has a population of approximately 6.7 billion people, roughly 86% of the world population. Related terms The following terms are used for similar concepts: * Ecumene: a term from classical antiquity for the world as was known to ancient Greek scholars, which was limited to Europe and parts of Asia and Africa. * Old World: a term from the Age of Discovery which, for European explorers, contrasted their previously known world from the New World of the Americas. * World Island: a term coined by H.J.

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life. While large volumes of water can be found throughout the Solar System, only Earth sustains liquid surface water. About 71% of Earth's surface is made up of the ocean, dwarfing Earth's polar ice, lakes, and rivers. The remaining 29% of Earth's surface is land, consisting of continents and islands. Earth's surface layer is formed of several slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's liquid outer core generates the magnetic field that shapes the magnetosphere of the Earth, deflecting destructive solar winds. The atmosphere of the Earth consists mostly of nitrogen and oxygen. Greenhouse gases in the atmosphere like carbon dioxide (CO2) trap a part of the energy from the Sun close to the surface. Water vapor is widely present in the atmosphere and forms clouds that cover most of the planet. More solar e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Supercontinent
In geology, a supercontinent is the assembly of most or all of Earth's continent, continental blocks or cratons to form a single large landmass. However, some geologists use a different definition, "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times. To separate supercontinents from other groupings, a limit has been proposed in which a continent must include at least about 75% of the continental crust then in existence in order to qualify as a supercontinent. Supercontinents have assembled and dispersed multiple times in the geologic past (see table). According to modern definitions, a supercontinent does not exist today; the closest in existence to a supercontinent is the current Afro-Eurasian landmass, which covers approx. 57% of Earth's total land area. The last time the continental landmasses were near to one another was 336 to 175 million years ago as the supercontinent, Pangaea. The positions of con ...

Age Of Discovery
The Age of Discovery (or the Age of Exploration), also known as the early modern period, was a period largely overlapping with the Age of Sail, approximately from the 15th century to the 17th century in European history, during which seafaring Europeans explored and colonized regions across the globe. The extensive overseas exploration, with the Portuguese and Spanish at the forefront, later joined by the Dutch, English, and French, emerged as a powerful factor in European culture, most notably the European encounter and colonization of the Americas. It also marks an increased adoption of colonialism as a government policy in several European states. As such, it is sometimes synonymous with the first wave of European colonization. European exploration outside the Mediterranean started with the maritime expeditions of Portugal to the Canary Islands in 1336, and later with the Portuguese discoveries of the Atlantic archipelagos of Madeira and Azores, the coast of West Afr ...

Geopolitics
Geopolitics (from Greek γῆ ''gê'' "earth, land" and πολιτική ''politikḗ'' "politics") is the study of the effects of Earth's geography (human and physical) on politics and international relations. While geopolitics usually refers to countries and relations between them, it may also focus on two other kinds of states: ''de facto'' independent states with limited international recognition and relations between sub-national geopolitical entities, such as the federated states that make up a federation, confederation, or a quasi-federal system. At the level of international relations, geopolitics is a method of studying foreign policy to understand, explain, and predict international political behavior through geographical variables. These include area studies, climate, topography, demography, natural resources, and applied science of the region being evaluated. Geopolitics focuses on political power linked to geographic space. In particular, territorial waters and l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Geographical Pivot Of History
"The Geographical Pivot of History" is an article submitted by Halford John Mackinder in 1904 to the Royal Geographical Society that advances his heartland theory.Mackinder, H. J."The Geographical Pivot of History" ''The Geographical Journal'', Vol. 23, No.4, (April 1904), pp. 421–437Mackinder, H. J., Democratic Ideals and Reality. A Study in the Politics of Reconstruction', National Defense University Press, 1996, pp. 175–193Charles Kruszewski"The Pivot of History" ''Foreign Affairs'', April 1954 In this article, Mackinder extended the scope of geopolitical analysis to encompass the entire globe. The World-Island and the Heartland According to Mackinder, the Earth's land surface was divisible into: *The World-Island, comprising the interlinked continents of Europe, Asia, and Africa (Afro-Eurasia). This was the largest, most populous, and richest of all possible land combinations. *The offshore islands, including the British Isles and the islands of Japan. *The outlying isla ...

Halford Mackinder
Sir Halford John Mackinder (15 February 1861 – 6 March 1947) was an English geographer, academic and politician, who is regarded as one of the founding fathers of both geopolitics and geostrategy. He was the first Principal of University Extension College, Reading (which became the University of Reading) from 1892 to 1903, and Director of the London School of Economics from 1903 to 1908. While continuing his academic career part-time, he was also the Member of Parliament for Glasgow Camlachie from 1910 to 1922. From 1923, he was Professor of Geography at the London School of Economics. Early life and education Mackinder was born in Gainsborough, Lincolnshire, England, the son of a doctor, and educated at Queen Elizabeth's Grammar School in Gainsborough, Epsom College and Christ Church, Oxford. At Oxford he started studying natural sciences, specialising in zoology under Henry Nottidge Moseley, who had been the naturalist on the ''Challenger'' expedition. When he turned to ...
