The Geography Portal

Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write', literally 'Earth writing') is the study of the lands, features, inhabitants, and phenomena of Earth. Geography is an all-encompassing discipline that seeks an understanding of Earth and its human and natural complexities—not merely where objects are, but also how they have changed and come to be. While geography is specific to Earth, many concepts can be applied more broadly to other celestial bodies in the field of planetary science. Geography has been called "a bridge between natural science and social science disciplines."

The history of geography as a discipline spans cultures and millennia, being independently developed by multiple groups, and cross-pollinated by trade between these groups. Geography as a discipline dates back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to the 9th century BC in ancient Babylon. Origins of many of the concepts in geography can be traced to Greek Eratosthenes of Cyrene, who may have coined the term "geographia" (c. 276 BC – c. 195/194 BC). The first recorded use of the word γεωγραφία was as the title of a book by Greek scholar Claudius Ptolemy (100 – 170 AD). During the Middle Ages, geography was influenced by Islamic scholars, like Muhammad al-Idrisi, producing detailed maps of the world. The Age of Discovery was influential in the development of geography, as European explorers mapped the New World. Modern developments include the development of geomatics and geographic information science.

The core concepts of geography consistent between all approaches are a focus on space, place, time, and scale. Today, geography is an extremely broad discipline with multiple approaches and modalities. The main branches of geography are physical geography, human geography, and technical geography. Physical geography focuses on the natural environment, human geography focuses on how humans interact with the Earth, and technical geography focuses on the development of tools for understanding geography. Techniques employed can generally be broken down into quantitative and qualitative approaches, with many studies taking mixed-methods approaches. Common techniques include cartography, remote sensing, interviews, and surveying. (Full article...)

William Feiner (born Wilhelm Feiner; December 27, 1792 – June 9, 1829) was a German Catholic priest and Jesuit who became a missionary to the United States and eventually the president of Georgetown College, now known as Georgetown University.

Born in Münster, he taught in Jesuit schools in the Russian Empire and Polish Galicia as a young member of the Society of Jesus. He then emigrated to the United States several years after the restoration of the Society, taking up pastoral work and teaching theology in Conewago, Pennsylvania, before becoming a full-time professor at Georgetown College. There, he also became the second dedicated librarian of Georgetown's library. Eventually, Feiner became president of the college in 1826. While president, he taught theology at Georgetown and ministered to the congregation at Holy Trinity Church. (Full article...)

The empire in 661, when it reached its greatest extent

The Tang dynasty (/tɑːŋ/; Chinese: 唐朝 [tʰɑ̌ŋ ʈʂʰɑ̌ʊ]), or the Tang Empire, was an imperial dynasty of China that ruled from 618 to 907, with an interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilisation, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivalled that of the Han dynasty.

The Li family founded the dynasty after taking advantage of a period of Sui decline and precipitating their final collapse, in turn inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant. The An Lushan rebellion (755–763) led to devastation and the decline of central authority during the latter half of the dynasty. (Full article...)

Male in Toronto, Ontario, Canada

The peregrine falcon (Falco peregrinus), also referred to simply as the peregrine, is a bird of prey (raptor) in the family Falconidae known for its speed. A large, crow-sized falcon, it has a blue-grey back, barred white underparts and a black head. As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males. Historically, the bird has also been known as the "black-cheeked falcon" in Australia, and the "duck hawk" in North America.

The breeding range includes land regions from the Arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests. The only major ice-free landmass from which it is entirely absent is New Zealand. That makes it the world's most widespread raptor and one of the most widely found wild bird species. In fact, the only land-based bird species found over a larger geographic area, domestic and feral pigeons, owe their success to human-led introduction. Both are domesticated forms of the rock dove, and are a major prey species for peregrine populations. Due to their greater abundance in cities than most other birds, feral pigeons support many peregrine populations as a staple food source, especially in urban settings. (Full article...)

The frontispiece of the 1920 edition of Tod's Annals and Antiquities of Rajast'han

Lieutenant-Colonel James Tod (20 March 1782 – 18 November 1835) was a British army officer and scholar. He combined his official role and his amateur interests to create a series of works about the history and geography of India, and in particular the area then known as Rajputana that corresponds to the present day state of Rajasthan, and which Tod referred to as Rajast'han.

Tod was born in London and educated in Scotland. He joined the East India Company as a military officer and travelled to India in 1799 as a cadet in the Bengal Army. He rose quickly in rank, eventually becoming captain of an escort for an envoy in a Sindian royal court. After the Third Anglo-Maratha War, during which Tod was involved in the intelligence department, he was appointed Political Agent for some areas of Rajputana. His task was to help unify the region under the control of the East India Company. During this period Tod conducted most of the research that he would later publish. Tod was initially successful in his official role, but his methods were questioned by other members of the East India Company. Over time, his work was restricted and his areas of oversight were significantly curtailed. In 1823, owing to declining health and reputation, Tod resigned his post as Political Agent and returned to England. (Full article...)

The Grade II listed steam crane at Mount Sion, on the Bury arm

The Manchester, Bolton and Bury Canal is a disused canal in Greater Manchester, England, built to link Bolton and Bury with Manchester. The canal, when fully opened, was 15 miles 1 furlong (24 km) long. It was accessed via a junction with the River Irwell in Salford. Seventeen locks were required to climb to the summit as it passed through Pendleton, heading northwest to Prestolee before it split northwest to Bolton and northeast to Bury. Between Bolton and Bury the canal was level and required no locks. Six aqueducts were built to allow the canal to cross the rivers Irwell and Tonge and several minor roads.

The canal was commissioned in 1791 by local landowners and businessmen and built between 1791 and 1808, during the Golden Age of canal building, at a cost of £127,700 (£9.28 million today). Originally designed for narrow gauge boats, during its construction the canal was altered into a broad gauge canal to allow an ultimately unrealised connection with the Leeds and Liverpool Canal. The canal company later converted into a railway company and built a railway line close to the canal's path, which required modifications to the Salford arm of the canal. (Full article...)

The Transcaucasian Democratic Federative Republic (TDFR; 22 April – 28 May 1918) was a short-lived state in the Caucasus that included most of the territory of the present-day Armenia, Azerbaijan and Georgia, as well as parts of Russia and Turkey. The state lasted only for a month before Georgia declared independence, followed shortly after by Armenia and Azerbaijan.

The region that formed the TDFR had been part of the Russian Empire. As the empire dissolved during the 1917 February Revolution and a provisional government took over, a similar body, called the Special Transcaucasian Committee (Ozakom), did the same in the Caucasus. After the October Revolution and rise of the Bolsheviks in Russia, the Transcaucasian Commissariat replaced the Ozakom. In March 1918, as the First World War continued, the Commissariat initiated peace talks with the Ottoman Empire, which had invaded the region, but the talks broke down quickly as the Ottomans refused to accept the authority of the Commissariat. The Treaty of Brest-Litovsk, which ended Russia's involvement in the war, conceded parts of the Transcaucasus to the Ottoman Empire, which pursued its invasion to take control of the territory. Faced with this imminent threat, on 22 April 1918 the Commissariat dissolved itself and established the TDFR as an independent state. A legislature, the Seim, was formed to direct negotiations with the Ottoman Empire, which had immediately recognized the state. (Full article...)

Payún Matrú

Payún Matrú is a shield volcano in the Reserva Provincial La Payunia of the Malargüe Department, south of the Mendoza Province in Argentina. It lies in the back-arc region of the Andean Volcanic Belt, and was formed by the subduction of the Nazca Plate beneath the South American Plate. Payún Matrú, along with the Llancanelo, Nevado and Salado Basin volcanic fields, form the Payenia province. It has been proposed as a World Heritage Site since 2011.

Payún Matrú developed on sediment and volcanic rocks ageing from the Mesoproterozoic to the Tertiary periods. It consists of a large shield volcano capped by a caldera, formed during a major eruption between 168,000 and 82,000 years ago, a high compound volcano (known as Payun or Payun Liso), and two groups of scoria cones and lava flows. The Pleistocene Pampas Onduladas lava flow reaches a length of 167–181 km (104–112 mi) and is the world's longest Quaternary lava flow. (Full article...)

Manchester skyscrapers and a Bee Network tram

Manchester is a city in Greater Manchester, England. It had a population of over 589,000 in 2024. It borders the Cheshire Plain to the south, the Pennines to the north and east, and the city of Salford to the west. The two cities and the surrounding towns form one of the United Kingdom's most populous conurbations, the Greater Manchester Built-up Area, which has a population of 2.87 million.

The history of Manchester began with the civilian settlement associated with the Roman fort of Mamucium or Mancunium, established around AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century. Throughout the Middle Ages Manchester remained a manorial township, but began to expand significantly with a boom in textile manufacture during the Industrial Revolution, which resulted in it becoming the world's first industrialised city. Manchester attained city status in 1853. The Manchester Ship Canal opened in 1894, creating the Port of Manchester and linking the city to the Irish Sea, 36 miles (58 km) to the west. Its fortune declined after the Second World War, owing to deindustrialisation, and the 1996 Manchester bombing led to extensive investment and regeneration. (Full article...)

The original letter from Balfour to Rothschild; the declaration reads:
His Majesty's Government view with favour the establishment in Palestine of a national home for the Jewish people, and will use their best endeavours to facilitate the achievement of this object, it being clearly understood that nothing shall be done which may prejudice the civil and religious rights of existing non-Jewish communities in Palestine, or the rights and political status enjoyed by Jews in any other country.

The Balfour Declaration was a public statement issued by the British Government in 1917 during the First World War announcing its support for the establishment of a "national home for the Jewish people" in Palestine, then an Ottoman region with a small minority Jewish population. The declaration was contained in a letter dated 2 November 1917 from Arthur Balfour, the British foreign secretary, to Lord Rothschild, a leader of the British Jewish community, for transmission to the Zionist Federation of Great Britain and Ireland. The text of the declaration was published in the press on 9 November 1917.

Following Britain's declaration of war on the Ottoman Empire in November 1914, it began to consider the future of Palestine. Within two months a memorandum was circulated to the War Cabinet by a Zionist member, Herbert Samuel, proposing the support of Zionist ambitions to enlist the support of Jews in the wider war. A committee was established in April 1915 by British prime minister H. H. Asquith to determine their policy towards the Ottoman Empire including Palestine. Asquith, who had favoured post-war reform of the Ottoman Empire, resigned in December 1916; his replacement David Lloyd George favoured partition of the Empire. The first negotiations between the British and the Zionists took place at a conference on 7 February 1917 that included Sir Mark Sykes and the Zionist leadership. Subsequent discussions led to Balfour's request, on 19 June, that Rothschild and Chaim Weizmann draft a public declaration. Further drafts were discussed by the British Cabinet during September and October, with input from Zionist and anti-Zionist Jews but with no representation from the local population in Palestine.

The Far Eastern Party was a sledging component of the 1911–1914 Australasian Antarctic expedition, which investigated the previously unexplored coastal regions of Antarctica west of Cape Adare. Led by Australian geologist Douglas Mawson, the party aimed to explore the area far to the east of their main base in Adélie Land, pushing about 500 miles (800 km) towards Victoria Land. Accompanying Mawson were Belgrave Edward Ninnis, a lieutenant in the Royal Fusiliers, and Swiss ski expert Xavier Mertz; the party used sledge dogs to increase their speed across the ice. Initially they made good progress, crossing two huge glaciers on their route south-east.

On 14 December 1912, with the party more than 311 miles (501 km) from the safety of the main base at Cape Denison, Ninnis and the sledge he was walking beside broke through the snow lid of a crevasse and were lost. Their supplies now severely compromised, Mawson and Mertz turned back west, gradually shooting the remaining sledge dogs for food to supplement their scarce rations. As they crossed the first glacier on their return journey Mertz became sick, making progress difficult. After almost a week of making very little headway Mertz died, leaving Mawson to carry on alone.

The Somerset Levels are a coastal plain and wetland area of Somerset, England, running south from the Mendips to the Blackdown Hills.

The Somerset Levels have an area of about 160,000 acres (650 km²) and are bisected by the Polden Hills; the areas to the south are drained by the River Parrett, and the areas to the north by the rivers Axe and Brue. The Mendip Hills separate the Somerset Levels from the North Somerset Levels. The Somerset Levels consist of marine clay "levels" along the coast and inland peat-based "moors"; agriculturally, about 70 per cent is used as grassland and the rest is arable. Willow and teazel are grown commercially and peat is extracted. (Full article...)

Calabozos is a Holocene caldera in central Chile's Maule Region (7th Region). Part of the Chilean Andes' volcanic segment, it is considered a member of the Southern Volcanic Zone (SVZ), one of the three distinct volcanic belts of South America. This most active section of the Andes runs along central Chile's western edge, and includes more than 70 of Chile's stratovolcanoes and volcanic fields. Calabozos lies in an extremely remote area of poorly glaciated mountains.

Calabozos and the majority of the Andean volcanoes formed from the subduction of the oceanic Nazca Plate under the continental South American continental lithosphere. The caldera is in a transitional region between thick and thin lithosphere, and is probably supplied by a pool of andesitic and rhyolitic magma. It sits on a historic bed of volcanic and plutonic sedimentary rock (rock formed within the Earth) that in turn sits on top of a layer of merged sedimentary and metamorphic rock. (Full article...)

Tiruchirappalli (Tamil pronunciation: [ˈt̪iɾɯtːʃiɾapːaɭːi] ), also known as Trichy or historically as Trichinopoly, is a major tier II city in the Indian state of Tamil Nadu and the administrative headquarters of Tiruchirappalli district. The city is credited with being the best livable and the cleanest city of Tamil Nadu, as well as the fifth safest city for women in India. It is the fourth largest urban agglomeration in the state. Located 322 kilometres (200 mi) south of Chennai and 374 kilometres (232 mi) north of Kanyakumari, Tiruchirappalli sits almost at the geographic centre of Tamil Nadu. The Cauvery Delta begins 16 kilometres (9.9 mi) west of the city where the Kaveri river splits into two, forming the island of Srirangam which is now incorporated into the Tiruchirappalli City Municipal Corporation. The city occupies an area of 167.23 square kilometres (64.57 sq mi) and had a population of 916,857 in 2011.

Tiruchirappalli's recorded history begins under Chola rule in the 3rd century BC. The city has also been ruled by the Pallavas, Pandyas, Vijayanagar Empire, Nayak Dynasty, the Carnatic state and the British. The most prominent historical monuments in Tiruchirappalli include the Rockfort at Teppakulam, the Ranganathaswamy temple at Srirangam dedicated to the reclining form of Hindu God Vishnu, and is also the largest functioning temple in the world, and the Jambukeswarar Temple at Thiruvanaikaval, which is also the largest temple for the Hindu God Shiva in the world. The archaeologically important town of Uraiyur, capital of the Early Cholas, is now a neighbourhood in Tiruchirappalli. The city played a critical role in the Carnatic Wars (1746–1763) between the British and the French East India companies. (Full article...)

RSPB Minsmere is a nature reserve owned and managed by the Royal Society for the Protection of Birds (RSPB) at Minsmere, Suffolk. The 1,000-hectare (2,500-acre) site has been managed by the RSPB since 1947 and covers areas of reed bed, lowland heath, acid grassland, wet grassland, woodland and shingle vegetation. It lies within the Suffolk Coast and Heaths Area of Outstanding Natural Beauty and the Suffolk Heritage Coast area. It is conserved as a Site of Special Scientific Interest, Special Area of Conservation, Special Protection Area and Ramsar site.

The nature reserve is managed primarily for bird conservation, particularly through control and improvement of wetland, heath and grassland habitats, with particular emphasis on encouraging nationally uncommon breeding species such as the bittern, stone-curlew, bearded tit, marsh harrier, nightjar and nightingale. The diversity of habitats has also led to a wide variety of other animals and plants being recorded on the site. (Full article...)

Tumbler Ridge is a district municipality in the foothills of the B.C. Rockies in northeastern British Columbia, Canada, and a member municipality of the Peace River Regional District. With a population of 2,399 (2021) living in a townsite, the municipality encompasses an area of 1,558 km² (602 sq mi) of mostly Crown land. The townsite is located near the confluence of the Murray River and Flatbed Creek and the intersection of Highway 52 and Highway 29 and includes the site of the Tumbler Ridge Secondary School and Tumbler Ridge Airport. The municipality is part of the Peace River South provincial electoral district and the Prince George—Peace River—Northern Rockies federal riding.

Tumbler Ridge is a planned community, with the housing and infrastructure built simultaneously in 1981 by the provincial government to service the coal industry as part of the British Columbia Resources Investment Corporation's Northeast Coal Development. In 1981, a consortium of Japanese steel mills agreed to purchase 100 million tonnes of coal over 15 years for US$7.5 billion from two mining companies, Denison Mines Inc. and the Teck Corporation, who were to operate the Quintette mine and the Bullmoose mine respectively. The uncertainty dissuaded investment and kept the economy from diversifying. When price reductions were forced onto the mines, the Quintette mine was closed in 2000 production and the town lost about half its population. Coal prices began to rise after the turn of the century, leading to the opening of the Peace River Coal Trend mine by Northern Energy & Mining Inc. (now owned by Anglo American Met Coal) and the Wolverine Mine, originally owned by Western Canadian Coal, which was purchased by Walter Energy in 2010. Walter went bankrupt in 2015, and their Canadian assets—including the Wolverine Mine—were purchased by Conuma Coal in 2016. (Full article...)

Vital article

Vital articles to understand Geography.

Land, also known as dry land, ground, or earth, is the solid terrestrial surface of Earth not submerged by the ocean or another body of water. It makes up 29.2% of Earth's surface and includes all continents and islands. Earth's land surface is almost entirely covered by regolith, a layer of rock, soil, and minerals that forms the outer part of the crust. Land plays an important role in Earth's climate system, being involved in the carbon cycle, nitrogen cycle, and water cycle. One-third of land is covered in trees, another third is used for agriculture, and one-tenth is covered in permanent snow and glaciers. The remainder consists of desert, savannah, and prairie.

The Catalan Atlas is a medieval map in the Catalan language, created in 1375. Described as "the zenith of medieval map-work", it is the earliest known chart to use a compass rose. It was produced by the Majorcan cartographic school and is attributed to Abraham Cresques, a Jewish book illuminator described by a contemporary as a master of mappae mundi. It has been in the royal library of France (now the Bibliothèque nationale de France) since the time of King Charles V. The atlas originally consisted of six vellum leaves, each about 64.5 by 50 cm (25.4 by 19.7 in), folded vertically and painted in various colours including gold and silver. This picture is a montage of eight pages (four leaves) of the atlas, depicting Europe, northern Africa and Asia.

Antarctica, the continent surrounding the Earth's South Pole, is the coldest place on Earth and is almost entirely covered by ice. Antarctica was discovered in late January 1820. Too cold and dry to support virtually any vascular plants, Antartica's flora presently consists of around 250 lichens, 100 mosses, 25-30 liverworts, and around 700 terrestrial and aquatic algal species.

Mercator projection
Map: Strebe, using Geocart
The Mercator projection is a cylindrical map projection presented by the Flemish geographer and cartographer Gerardus Mercator in 1569. Because it represents paths of constant course as straight lines, it long served as the standard map projection for nautical purposes. However, it distorts the size of objects as the latitude increases: thus areas in the mid-latitudes appear significantly larger than their actual size relative to those the equator, and those near the poles are even more exaggerated. Most modern atlases no longer use the Mercator projection for world maps or for areas distant from the equator, preferring other cylindrical projections, or forms of equal-area projection.

Gall–Peters projection
Map: Strebe, using Geocart
The Gall–Peters projection, named after James Gall and Arno Peters, is a specialization of a configurable equal-area map projection known as the cylindrical equal-area projection. It achieved considerable notoriety in the late 20th century as the centerpiece of a controversy surrounding the political implications of map design; Peters promoted it as a more faithful representation than the Mercator projection, which inflates the sizes of regions farther from the equator and thus makes the (mostly technologically underdeveloped) equatorial countries appear smaller and therefore, according to Peters, less significant.

The Hammer retroazimuthal projection is a modified azimuthal proposed by Ernst Hermann Heinrich Hammer in 1910. As a retroazimuthal projection, azimuths (directions) are correct from any point to the designated center point. In whole-world presentation, the back and front hemispheres overlap, making the projection a surjective function. Here, the frontside and backside hemispheres, both with a 15° graticule and center point of 45°N, 90°W, are presented side-by-side.

Portrait of Cope, c. 1895

Edward Drinker Cope (July 28, 1840 – April 12, 1897) was an American zoologist, paleontologist, comparative anatomist, herpetologist, and ichthyologist. Born to a wealthy Quaker family, he distinguished himself as a child prodigy interested in science, publishing his first scientific paper at the age of 19. Though his father tried to raise Cope as a gentleman farmer, he eventually acquiesced to his son's scientific aspirations.

Cope had little formal scientific training, and he eschewed a teaching position for field work. He made regular trips to the American West, prospecting in the 1870s and 1880s, often as a member of U.S. Geological Survey teams. A personal feud between Cope and paleontologist Othniel Charles Marsh led to a period of intense fossil-finding competition now known as the Bone Wars. Cope's financial fortunes soured after failed mining ventures in the 1880s, forcing him to sell off much of his fossil collection. He experienced a resurgence in his career toward the end of his life before dying on April 12, 1897. (Full article...)
