Geography (from Greek: γεωγραφία, geographia. Combination of Greek words 'Geo' (The Earth) and 'Graphien' (to describe), literally "earth description") is a field of science devoted to 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 first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). However, the concepts of geography (such as cartography) date back to the earliest attempts to understand the world spatially, with the earliest example of an attempted world map dating to the 9th century BCE in ancient Babylon. 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. 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. There have been multiple attempts to organize the discipline, including the four traditions of geography, and into branches. 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 surveys. (Full article...)

Visitors descend the downstream side of Dam 1 on the Bull Run River.

The Bull Run River is a 21.9-mile (35.2 km) tributary of the Sandy River in the U.S. state of Oregon. Beginning at the lower end of Bull Run Lake in the Cascade Range, it flows generally west through the Bull Run Watershed Management Unit (BRWMU), a restricted area meant to protect the river and its tributaries from contamination. The river, impounded by two artificial storage reservoirs as well as the lake, is the primary source of drinking water for the city of Portland, Oregon.

It is likely that Native Americans living along the Columbia River as early as 10,000 years ago visited the Bull Run watershed in search of food. Within the past few thousand years they created trails over the Cascade Range and around Mount Hood, near the upper part of the Bull Run watershed. By the mid-19th century, pioneers used these trails to cross the mountains from east to west to reach the fertile Willamette Valley. In the 1890s, the City of Portland, searching for sources of clean drinking water, chose the Bull Run River. Dam-building, road construction, and legal action to protect the watershed began shortly thereafter, and Bull Run water began to flow through a large pipe to the city in 1895. (Full article...)

Australia, officially the Commonwealth of Australia, is a sovereign country comprising the mainland of the Australian continent, the island of Tasmania, and numerous smaller islands. Australia is the largest country by area in Oceania and the world's sixth-largest country. Australia is the oldest, flattest, and driest inhabited continent, with the least fertile soils. It is a megadiverse country, and its size gives it a wide variety of landscapes and climates, with deserts in the centre, tropical rainforests in the north-east, tropical savannas in the north, and mountain ranges in the south-east.

The ancestors of Aboriginal Australians began arriving from south-east Asia 50,000 to 65,000 years ago, during the last glacial period. Arriving by sea, they settled the continent and had formed approximately 250 distinct language groups by the time of European settlement, maintaining some of the longest known continuing artistic and religious traditions in the world. Australia's written history commenced with the European maritime exploration of Australia. The Dutch navigator Willem Janszoon was the first known European to reach Australia, in 1606. In 1770, the British explorer James Cook mapped and claimed the east coast of Australia for Great Britain, and the First Fleet of British ships arrived at Sydney in 1788 to establish the penal colony of New South Wales. The European population grew in subsequent decades, and by the end of the 1850s gold rush, most of the continent had been explored by European settlers and an additional five self-governing British colonies were established. Democratic parliaments were gradually established through the 19th century, culminating with a vote for the federation of the six colonies and foundation of the Commonwealth of Australia on 1 January 1901. This began a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster Adoption Act 1942, and culminating in the Australia Act 1986. (Full article...)

Sale Town Hall

Sale is a town in Trafford, Greater Manchester, England, in the historic county of Cheshire on the south bank of the River Mersey, 2 miles (3.2 km) south of Stretford, 3 miles (4.8 km) northeast of Altrincham, and 5 miles (8.0 km) southwest of Manchester. In 2021, it had a population of 54,515.

Evidence of Stone Age, Roman and Anglo-Saxon activity has previously been discovered locally. In the Middle Ages, Sale was a rural township, linked ecclesiastically with neighbouring Ashton upon Mersey, whose fields and meadows were used for crop and cattle farming. By the 17th century, Sale had a cottage industry manufacturing garthweb, the woven material from which horses' saddle girths were made. (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...)

Mount Sylvania in Portland, Oregon, one of the major volcanoes in the field

The Boring Lava Field (also known as the Boring Volcanic Field) is a Plio-Pleistocene volcanic field with cinder cones, small shield volcanoes, and lava flows in the northern Willamette Valley of the U.S. state of Oregon and adjacent southwest Washington. The field got its name from the town of Boring, Oregon, located 12 miles (20 km) southeast of downtown Portland. Boring lies southeast of the densest cluster of lava vents. The zone became volcanically active about 2.7 million years ago, with long periods of eruptive activity interspersed with quiescence. Its last eruptions took place about 57,000 years ago at the Beacon Rock cinder cone volcano; the individual volcanic vents of the field are considered extinct, but the field itself is not.

The Boring Lava Field covers an area of about 1,500 square miles (4,000 km²), and has a total volume of 2.4 cubic miles (10 km³). This region sustains diverse flora and fauna within its habitat areas, which are subject to Portland's moderate climate with variable temperatures and mild precipitation. The highest elevation of the field is at Larch Mountain, which reaches a height of 4,055 feet (1,236 m). (Full article...)

Robert Falcon Scott in 1905

Captain Robert Falcon Scott (6 June 1868 – c. 29 March 1912) was a British Royal Navy officer and explorer who led two expeditions to the Antarctic regions: the Discovery expedition of 1901–04 and the Terra Nova expedition of 1910–13.

On the first expedition, he set a new southern record by marching to latitude 82°S and discovered the Antarctic Plateau, on which the South Pole is located. On the second venture, Scott led a party of five which reached the South Pole on 17 January 1912, less than five weeks after Amundsen's South Pole expedition. A planned meeting with supporting dog teams from the base camp failed, despite Scott's written instructions, and at a distance of 162 miles (261 km) from their base camp at Hut Point and approximately 12.5 miles (20.1 km) from the next depot, Scott and his companions died. When Scott and his party's bodies were discovered, they had in their possession the first Antarctic fossils discovered. The fossils were determined to be from the Glossopteris tree and proved that Antarctica was once forested and joined to other continents. (Full article...)

Triton is the largest natural satellite of the planet Neptune, and was the first Neptunian moon to be discovered, on October 10, 1846, by English astronomer William Lassell. It is the only large moon in the Solar System with a retrograde orbit, an orbit in the direction opposite to its planet's rotation. Because of its retrograde orbit and composition similar to Pluto, Triton is thought to have been a dwarf planet, captured from the Kuiper belt.

At 2,710 kilometers (1,680 mi) in diameter, it is the seventh-largest moon in the Solar System, the only satellite of Neptune massive enough to be in hydrostatic equilibrium, the second-largest planetary moon in relation to its primary (after Earth's Moon), and larger than Pluto. Triton is one of the few moons in the Solar System known to be geologically active (the others being Jupiter's Io and Europa, and Saturn's Enceladus and Titan) as well as suspected to contain an internal, active layer of liquid ocean, similar to the aforementioned moons. As a consequence, its surface is relatively young, with few obvious impact craters. Intricate cryovolcanic and tectonic terrains suggest a complex geological history. Triton has a surface of mostly frozen nitrogen, a mostly water-ice crust, an icy mantle and a substantial core of rock and metal. The core makes up two-thirds of its total mass. The mean density is 2.061 g/cm³, reflecting a composition of approximately 15–35% water ice. (Full article...)

The Isle of Skye, or simply Skye (/skaɪ/; Scottish Gaelic: An t-Eilean Sgitheanach or Eilean a' Cheò), is the largest and northernmost of the major islands in the Inner Hebrides of Scotland. The island's peninsulas radiate from a mountainous hub dominated by the Cuillin, the rocky slopes of which provide some of the most dramatic mountain scenery in the country. Although Sgitheanach has been suggested to describe a winged shape, no definitive agreement exists as to the name's origins.

The island has been occupied since the Mesolithic period, and over its history has been occupied at various times by Celtic tribes including the Picts and the Gaels, Scandinavian Vikings, and most notably the powerful integrated Norse-Gaels clans of
MacLeod and MacDonald. The island was considered to be under Norwegian suzerainty until the 1266 Treaty of Perth, which transferred control over to Scotland. (Full article...)

W. R. Brown

William Robinson "W. R. " Brown (January 17, 1875 – August 4, 1955) was an American corporate officer of the Brown Company of Berlin, New Hampshire. He was also an influential Arabian horse breeder, the founder and owner of the Maynesboro Stud, and an authority on Arabian horses.

After graduating from Williams College, Brown joined the family corporation, then known as the Berlin Mills Company, and became manager of the Woods Products Division, overseeing the company's woodlands and logging operations. He became an early advocate for sustainable forest management practices, was a member of the New Hampshire Forestry Commission from 1909 until 1952, and served on the boards of several forestry organizations. As chair of the Forestry Commission, Brown helped send sawmills to Europe during World War I to assist the war effort. He was influenced by the Progressive movement, instituting employee benefits such as company-sponsored care for injured workers that predated modern workers' compensation laws. As a Republican, he served as a presidential elector for New Hampshire in 1924. (Full article...)

November 2022 satellite image of the glacier by Sentinel-2.

The Quelccaya Ice Cap (also known as Quenamari Ice Cap) is the second largest glaciated area in the tropics, after Coropuna. Located in the Cordillera Oriental section of the Andes mountains in Peru, the cap covers an area of 42.8 square kilometres (16.5 sq mi) with ice up to 200 metres (660 ft) thick. It is surrounded by tall ice cliffs and a number of outlet glaciers, the largest of which is known as Qori Kalis Glacier; lakes, moraines, peat bogs and wetlands are also present. There is a rich flora and fauna, including birds that nest on the ice cap. Quelccaya is an important source of water, eventually melting and flowing into the Inambari and Vilcanota Rivers.

A number of ice cores have been obtained from Quelccaya, including two from 1983 that were the first recovered outside of the polar regions. Past climate states have been reconstructed from data in these ice cores; these include evidence of the Little Ice Age, regional droughts and wet periods with historical significance and past and recent El Niño events. The ice cap is regularly monitored and has a weather station. (Full article...)

Canada is a country in North America. Its ten provinces and three territories extend from the Atlantic Ocean to the Pacific Ocean and northward into the Arctic Ocean, making it the world's second-largest country by total area, with the world's longest coastline. Its border with the United States is the world's longest international land border. The country is characterized by a wide range of both meteorologic and geological regions. It is a sparsely inhabited country of 40 million people, the vast majority residing south of the 55th parallel in urban areas. Canada's capital is Ottawa and its three largest metropolitan areas are Toronto, Montreal, and Vancouver.

Indigenous peoples have continuously inhabited what is now Canada for thousands of years. Beginning in the 16th century, British and French expeditions explored and later settled along the Atlantic coast. As a consequence of various armed conflicts, France ceded nearly all of its colonies in North America in 1763. In 1867, with the union of three British North American colonies through Confederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom, highlighted by the Statute of Westminster, 1931, and culminating in the Canada Act 1982, which severed the vestiges of legal dependence on the Parliament of the United Kingdom.

Location in the Marshall Islands

Wōdejebato (formerly known as Sylvania) is a Cretaceous guyot or tablemount in the northern Marshall Islands, Pacific Ocean. Wōdejebato is probably a shield volcano and is connected through a submarine ridge to the smaller Pikinni Atoll 74 kilometres (46 mi) southeast of the guyot; unlike Wōdejebato, Pikinni rises above sea level. The seamount rises for 4,420 metres (14,500 ft) to 1,335 metres (4,380 ft) depth and is formed by basaltic rocks. The name Wōdejebato refers to a sea god of Pikinni.

It was probably formed by a hotspot in what is present-day French Polynesia before plate tectonics moved it to its present-day location. The Macdonald, Rarotonga, Rurutu and Society hotspots may have been involved in its formation. The first volcanic phase took place in the Cenomanian and was followed by the formation of a carbonate platform that quickly disappeared below the sea. A second volcanic episode between 85 and 78.4 million years ago (in the Campanian) led to the formation of an island. This island was eventually eroded and rudist reefs generated an atoll or atoll-like structure, covering the former island with carbonates and thus a second carbonate platform. (Full article...)

Freshwater lagoon seen from west bank, with Island Hide in the foreground, and the Parrinder wall and hides further back

Titchwell Marsh is an English nature reserve owned and managed by the Royal Society for the Protection of Birds (RSPB). Located on the north coast of the county of Norfolk, between the villages of Titchwell and Thornham, about 8 km (5.0 mi) east of the seaside resort of Hunstanton, its 171 hectares (420 acres) include reed beds, saltmarshes, a freshwater lagoon and sandy beach, with a small woodland area near the car park. This internationally important reserve is part of the North Norfolk Coast Site of Special Scientific Interest (SSSI) and the Norfolk Coast Area of Outstanding Natural Beauty (AONB), and is also protected through Natura 2000, Special Protection Area (SPA) and Ramsar listings.

The reserve is important for some scarce breeding birds, such as pied avocets on the islands, and western marsh harriers, Eurasian bitterns and bearded reedlings in the reeds. To encourage bitterns to breed, the reed beds have been improved to make them wetter, and the lagoon has been stocked with the common rudd. Typical wetland birds such as the water rail, reed warbler and sedge warbler also appear, and little egrets are common. The reserve has regularly attracted rarities, as its location is important for migrating birds. Ducks and geese winter at Titchwell in considerable numbers, and the reserve shelters the endangered European water vole. (Full article...)

Front of the church

Old Pine Church, also historically known as Mill Church, Nicholas Church, and Pine Church, is a mid-19th century church located near to Purgitsville, West Virginia, United States. It is among the earliest extant log churches in Hampshire County, along with Capon Chapel and Mount Bethel Church.

The church was constructed in 1838 to serve as a nondenominational "union church". As many of the Mill Creek valley's earliest settlers were of German descent, Old Pine Church may also have been built as a meeting place for Schwarzenau Brethren adherents, known as "Dunkers" or "Dunkards". The church is believed to have also been a meeting place for German Methodist settlers. By 1870, the church was primarily used by the Brethren denomination, and in 1878, the church's congregation split into White Pine Church of the Brethren and Old Pine Church congregations. Both congregations continued to use the church until 1907. (Full article...)

The Count of Porto Alegre around age 61, c. 1865

Manuel Marques de Sousa, Count of Porto Alegre (13 June 1804 – 18 July 1875), nicknamed "the Gloved Centaur", was an army officer, politician and abolitionist of the Empire of Brazil. Born into a wealthy family of military background, Manuel Marques de Sousa joined the Portuguese Army in Brazil in 1817 when he was little more than a child. His military initiation occurred in the conquest of the Banda Oriental (Eastern Bank), which was annexed and became the southernmost Brazilian province of Cisplatina in 1821. For most of the 1820s, he was embroiled in the Brazilian effort to keep Cisplatina as part of its territory: first during the struggle for Brazilian independence and then in the Cisplatine War. It would ultimately prove a futile attempt, as Cisplatina successfully separated from Brazil to become the independent nation of Uruguay in 1828.

A few years later, in 1835 his native province of Rio Grande do Sul was engulfed in a secessionist rebellion, the Ragamuffin War. The conflict lasted for almost ten years, and the Count was leading military engagements for most of that time. He played a decisive role in saving the provincial capital from the Ragamuffin rebels, allowing forces loyal to the legitimate government to secure a key foothold. In 1852, he led a Brazilian division during the Platine War in an invasion of the Argentine Confederation that overthrew its dictator. He was awarded a noble title, eventually raised from baron to viscount and finally to count. (Full article...)

Catalan Atlas
Map credit: Abraham Cresques
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.

Robinson projection
Map credit: Central Intelligence Agency
The Robinson projection is a projection of a world map showing the entire Earth at once. It was specifically created in an attempt to find a good compromise to the problem of showing the whole globe as a single flat image. The projection was devised by Arthur H. Robinson in 1963; distortion is severe close to the poles, but quickly declines to moderate levels as latitudes decrease. This Robinson-projection map, with standard parallels of 38°N and 38°S, was produced by the United States Central Intelligence Agency and shows the world as of February 2016.

The Yukon Delta is a river delta formed by the Yukon River as it drains into the Bering Sea. It is part of the larger Yukon–Kuskokwim Delta, which includes the delta of the Kuskokwim River. The Yukon River rises in British Columbia, Canada, and flows through Yukon before entering the U.S. state of Alaska. This August 2017 satellite image of the Yukon Delta shows how the river branches into numerous distributary channels that meander through the low-lying terrain on their way to the sea. The sandy colour of these channels and the coastal water is indicative of the marine sediment the river carries to the sea at this time of year.

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.

Compass rose
Illustration credit: Joaquim Alves Gaspar, after Jorge de Aguiar
A compass rose, sometimes called a windrose or rose of the winds, is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is also the term for the graduated markings found on the traditional magnetic compass. Today, a form of compass rose is found on, or featured in, almost all navigation systems, including nautical charts, non-directional beacons, VHF omnidirectional range systems, GPS, and similar equipment.

This picture is an illustration of a compass rose, copied from a 1492 portolan chart by Portuguese navigator and cartographer Jorge de Aguiar, now in the Beinecke Rare Book & Manuscript Library.

Chamberlin trimetric projection
Map: Strebe, using Geocart
The Chamberlin trimetric projection is a map projection where three points are fixed on the globe and the points on the sphere are mapped onto a plane by triangulation. It was developed in 1946 by Wellman Chamberlin for the National Geographic Society. It is neither conformal nor equal-area, but rather attempts to minimize distortion of distances everywhere with the side-effect of balancing between areal equivalence and conformality.

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.

Typhoon Noru
Photograph credit: NASA; edited by Meow
Typhoon Noru was the second-longest lasting tropical cyclone of the northwest Pacific Ocean on record. The fifth named storm of the 2017 Pacific typhoon season, it formed on July 19 and reached peak intensity on July 31 with 175 km/h (110 mph) 10-minute sustained winds. By this time, as shown in this satellite image, the typhoon was located south of Iwo Jima, and had taken on annular characteristics, with a symmetric ring of deep convection surrounding a 30 km (19 mi) well defined eye and fairly uniform cloud top temperatures. Traveling northwestward over an area of low ocean heat content, the eye became enlarged and ragged as the system weakened. By the time Noru made landfall over Wakayama Prefecture, Japan, on August 7, it had been downgraded to a severe tropical storm. It then dissipated over the Sea of Japan on August 9 as an extratropical cyclone.

A composite satellite image of the geography of Africa, the Earth's second-largest continent, and its adjacent islands. Separated from Europe by the Mediterranean Sea and from much of Asia by the Red Sea, Africa is joined to Asia at its northeast extremity by the Isthmus of Suez. For geopolitical purposes, the Sinai Peninsula – east of the Suez Canal – is often considered part of Africa, although geographically it belongs in Asia. Africa can be divided into a number of geographic zones: The Atlas Mountains in the north, the Sahara, the coastal plains, and the inner plateaus.

Bust of Shen at the Beijing Ancient Observatory

Shen Kuo (Chinese: 沈括; 1031–1095) or Shen Gua, courtesy name Cunzhong (存中) and pseudonym Mengqi (now usually given as Mengxi) Weng (夢溪翁), was a Chinese polymath, scientist, and statesman of the Song dynasty (960–1279). Shen was a master in many fields of study including mathematics, optics, and horology. In his career as a civil servant, he became a finance minister, governmental state inspector, head official for the Bureau of Astronomy in the Song court, Assistant Minister of Imperial Hospitality, and also served as an academic chancellor. At court his political allegiance was to the Reformist faction known as the New Policies Group, headed by Chancellor Wang Anshi (1021–1085).

In his Dream Pool Essays or Dream Torrent Essays (夢溪筆談; Mengxi Bitan) of 1088, Shen was the first to describe the magnetic needle compass, which would be used for navigation (first described in Europe by Alexander Neckam in 1187). Shen discovered the concept of true north in terms of magnetic declination towards the north pole, with experimentation of suspended magnetic needles and "the improved meridian determined by Shen's [astronomical] measurement of the distance between the pole star and true north". This was the decisive step in human history to make compasses more useful for navigation, and may have been a concept unknown in Europe for another four hundred years (evidence of German sundials made circa 1450 show markings similar to Chinese geomancers' compasses in regard to declination).
