P:GEO

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. The first recorded use of the word γεωγραφία was as a title of a book by Greek scholar Eratosthenes (276–194 BC). 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. One such concept, the first law of geography, proposed by Waldo Tobler, is "everything is related to everything else, but near things are more related than distant things." Geography has been called "the world discipline" and "the bridge between the human and the physical sciences." (Full article...)

Lock Haven is the county seat of Clinton County, in the U.S. state of Pennsylvania. Located near the confluence of the West Branch Susquehanna River and Bald Eagle Creek, it is the principal city of the Lock Haven Micropolitan Statistical Area, itself part of the Williamsport–Lock Haven combined statistical area. At the 2010 census, Lock Haven's population was 9,772.

Built on a site long favored by pre-Columbian peoples, Lock Haven began in 1833 as a timber town and a haven for loggers, boatmen, and other travelers on the river or the West Branch Canal. Resource extraction and efficient transportation financed much of the city's growth through the end of the 19th century. In the 20th century, a light-aircraft factory, a college, and a paper mill, along with many smaller enterprises, drove the economy. Frequent floods, especially in 1972, damaged local industry and led to a high rate of unemployment in the 1980s. (Full article...)

Dom Pedro Afonso (19 July 1848 – 10 January 1850) was the Prince Imperial and heir apparent to the throne of the Empire of Brazil. Born at the Palace of São Cristóvão in Rio de Janeiro, he was the second son and youngest child of Emperor Dom Pedro II and Dona Teresa Cristina of the Two Sicilies, and thus a member of the Brazilian branch of the House of Braganza. Pedro Afonso was seen as vital to the future viability of the monarchy, which had been put in jeopardy by the death of his older brother Dom Afonso almost three years earlier.

Pedro Afonso's death from fever at the age of one devastated the Emperor, and the imperial couple had no further children. Pedro Afonso's older sister Dona Isabel became heiress, but Pedro II was unconvinced that a woman could ever be accepted as monarch by the ruling elite. He excluded Isabel from matters of state and failed to provide training for her possible role as empress. With no surviving male children, the Emperor came to understand that the imperial line was destined to end with his own death. (Full article...)

Lake Estancia was a lake formed in the Estancia Valley, central New Mexico, which left various coastal landforms in the valley. The lake was mostly fed by creek and groundwater from the Manzano Mountains, and fluctuated between freshwater stages and saltier stages. The lake had a diverse fauna, including cutthroat trout; they may have reached it during a possible past stage where it was overflowing.

Lake Estancia appears to have formed between the Pliocene and Pleistocene, when a previous river system broke up. It reached a maximum water level ("highstand") presumably during the Illinoian glaciation and subsequently fluctuated between fuller stages and a desiccated basin. Around the Last Glacial Maximum (LGM) time interval, several highstands and a low water level state occurred during the "Big Dry" climate interval. Between 16,100 and 14,500 years ago the lake reached its highest stand of the last 30,000 years before drying up again during the Bølling-Allerød climate interval. The lake briefly returned during the Younger Dryas climate interval and eventually desiccated after about 8,500 years ago during the Holocene. Wind-driven erosion has excavated depressions in the former lakebed that are in part filled with playas (dry lake beds). (Full article...)

Alien vs. Predator (stylized as AVP: Alien vs. Predator) is a 2004 science fiction action film written and directed by Paul W. S. Anderson, and starring Sanaa Lathan, Raoul Bova, Lance Henriksen, Ewen Bremner, Colin Salmon, and Tommy Flanagan. It is the first film installment of the Alien vs. Predator franchise, adapting a crossover bringing together the eponymous creatures of the Alien and Predator series, a concept which originated in a 1989 comic book written by Randy Stradley and Chris Warner. Anderson wrote the story, with the creators of the Alien franchise, Dan O'Bannon and Ronald Shusett receiving additional story credit due to the incorporation of elements from the Alien series, and Anderson and Shane Salerno adapted the story into a screenplay. Their writing was influenced by Aztec mythology, the comic book series, and the writings of Erich von Däniken. In the film, scientists are caught in the crossfire of an ancient battle between Aliens and Predators as they attempt to escape a bygone pyramid.

Alien vs. Predator was theatrically released on 12 August 2004. Despite negative reviews, it grossed $177.4 million worldwide against a production budget of $60–70 million. A direct sequel, Aliens vs. Predator: Requiem, was released in 2007. (Full article...)

A view of Chew Stoke

Chew Stoke is a small village and civil parish in the affluent Chew Valley, in Somerset, England, about 8 miles (13 km) south of Bristol and 10 miles north of Wells. It is at the northern edge of the Mendip Hills, a region designated by the United Kingdom as an Area of Outstanding Natural Beauty, and is within the Bristol/Bath green belt. The parish includes the hamlet of Breach Hill, which is approximately 2 miles (3.2 km) southwest of Chew Stoke itself.

Chew Stoke has a long history, as shown by the number and range of its heritage-listed buildings. The village is at the northern end of Chew Valley Lake, which was created in the 1950s, close to a dam, pumping station, sailing club, and fishing lodge. A tributary of the River Chew, which rises in Strode, runs through the village. (Full article...)

The empire in 661, when it reached its greatest extent

The Tang dynasty (/tɑːŋ/, [tʰǎŋ]; Chinese: 唐朝), or 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 civilization, and a golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty.

The Lǐ family (李) founded the dynasty, seizing power during the decline and collapse of the Sui Empire and 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 devastating An Lushan Rebellion (755–763) shook the nation and led to the decline of central authority in the dynasty's latter half. Like the previous Sui dynasty, the Tang maintained a civil-service system by recruiting scholar-officials through standardized examinations and recommendations to office. The rise of regional military governors known as jiedushi during the 9th century undermined this civil order. The dynasty and central government went into decline by the latter half of the 9th century; agrarian rebellions resulted in mass population loss and displacement, widespread poverty, and further government dysfunction that ultimately ended the dynasty in 907.

Hamilton is a port city in the Canadian province of Ontario. Hamilton has a population of 569,353, and its census metropolitan area, which includes Burlington and Grimsby, has a population of 785,184. The city is approximately 45 kilometres (28 mi) southwest of Toronto in the Greater Toronto and Hamilton Area (GTHA).

Conceived by George Hamilton when he purchased the Durand farm shortly after the War of 1812, the town of Hamilton became the centre of a densely populated and industrialized region at the west end of Lake Ontario known as the Golden Horseshoe. On January 1, 2001, the current boundaries of Hamilton were created through the amalgamation of the original city with other municipalities of the Regional Municipality of Hamilton–Wentworth. Residents of the city are known as Hamiltonians. (Full article...)

Occupation and partition of Yugoslavia in 1941. The Hungarian-occupied then annexed areas of Yugoslavia are in the north (Bačka and Baranja) and northwest (Međimurje and Prekmurje).

During World War II, the Kingdom of Hungary engaged in the military occupation, then annexation, of the Bačka, Baranja, Međimurje and Prekmurje regions of the Kingdom of Yugoslavia. These territories had all been under Hungarian rule prior to 1920, and had been transferred to Yugoslavia as part of the post-World War I Treaty of Trianon. They now form part of several states: Yugoslav Bačka is now part of Vojvodina, an autonomous province of Serbia, Yugoslav Baranja and Međimurje are part of modern-day Croatia, and Yugoslav Prekmurje is part of modern-day Slovenia. The occupation began on 11 April 1941 when 80,000 Hungarian troops crossed the Yugoslav border in support of the German-led Axis invasion of Yugoslavia that had commenced five days earlier. There was some resistance to the Hungarian forces from Serb Chetnik irregulars, but the defences of the Royal Yugoslav Army had collapsed by this time. The Hungarian forces were indirectly aided by the local Volksdeutsche, the German minority, which had formed a militia and disarmed around 90,000 Yugoslav troops. Despite only sporadic resistance, Hungarian troops killed many civilians during these initial operations, including some Volksdeutsche. The government of the newly formed Axis puppet state, the Independent State of Croatia, subsequently consented to the Hungarian annexation of the Međimurje area, which dismayed the Croat population of the region.

The occupation authorities immediately classified the population of Bačka and Baranja into those that had lived in those regions when they had last been under Hungarian rule in 1920 and the mostly Serb settlers who had arrived since the areas had been part of Yugoslavia. They then began herding thousands of local Serbs into concentration camps and expelled them to the Independent State of Croatia, Italian-occupied Montenegro, and the German-occupied territory of Serbia. Ultimately, tens of thousands of Serbs were deported from the occupied territories. This was followed by the implementation of a policy of "magyarisation" of the political, social and economic life of the occupied territories, which included the re-settlement of Hungarians and Székelys from other parts of Hungary. "Magyarisation" did not impact the Volksdeutsche, who received special status under Hungarian rule, and in Prekmurje the Hungarian authorities were more permissive towards ethnic Slovenes.

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 that 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...)

Map showing Morrell's reported location of the "New South Greenland" coast (1823, red line), and "Ross's Appearance" as reported by Sir James Clark Ross in 1841. The dotted line indicates the area of Captain Johnson's 1821 voyage.

New South Greenland, sometimes known as Morrell's Land, was an appearance of land recorded by the American captain Benjamin Morrell of the schooner Wasp in March 1823, during a sealing and exploration voyage in the Weddell Sea area of Antarctica. Morrell provided precise coordinates and a description of a coastline which he claimed to have sailed along for more than 300 miles (480 km). Because the Weddell Sea area was so little visited and hard to navigate due to ice conditions, the alleged land was never properly investigated before its existence was emphatically disproved during Antarctic expeditions in the early 20th century.

At the time of Morrell's voyage, the geography of the then unnamed Weddell Sea and its surrounding coasts was almost entirely unknown, making the claimed sighting initially plausible. However, obvious errors in Morrell's voyage account and his general reputation as a fabulist created scepticism about the existence of this new land. In June 1912 the German explorer Wilhelm Filchner searched for but found no traces of land after his ship Deutschland became icebound in the Weddell Sea and drifted into the locality of Morrell's observation. A sounding of the sea bottom revealed more than 5,000 feet (1,500 m) of water, indicating no land in near proximity. Three years later, trapped in the same waters with his ship Endurance, Ernest Shackleton was able by similar means to confirm the land's non-existence. (Full article...)

Title page of the first edition of Wright's Certaine Errors in Navigation (1599)

Edward Wright (baptised 8 October 1561; died November 1615) was an English mathematician and cartographer noted for his book Certaine Errors in Navigation (1599; 2nd ed., 1610), which for the first time explained the mathematical basis of the Mercator projection by building on the works of Pedro Nunes, and set out a reference table giving the linear scale multiplication factor as a function of latitude, calculated for each minute of arc up to a latitude of 75°. This was in fact a table of values of the integral of the secant function, and was the essential step needed to make practical both the making and the navigational use of Mercator charts.

Wright was born at Garveston in Norfolk and educated at Gonville and Caius College, Cambridge, where he became a fellow from 1587 to 1596. In 1589 the college granted him leave after Elizabeth I requested that he carry out navigational studies with a raiding expedition organised by the Earl of Cumberland to the Azores to capture Spanish galleons. The expedition's route was the subject of the first map to be prepared according to Wright's projection, which was published in Certaine Errors in 1599. The same year, Wright created and published the first world map produced in England and the first to use the Mercator projection since Gerardus Mercator's original 1569 map. (Full article...)

Nevados de Putre, Taapaca volcano (right)

Taapaca is a Holocene volcanic complex in northern Chile's Arica y Parinacota Region. Located in the Chilean Andes, it is part of the Central Volcanic Zone of the Andean Volcanic Belt, one of four distinct volcanic chains in South America. The town of Putre lies at the southwestern foot of the volcano.

Like other volcanoes of the Central Volcanic Zone, Taapaca formed from the subduction of the Nazca Plate beneath the South America Plate. It lies on the western margin of the Altiplano high plateau, on top of older volcanic and sedimentary units. Taapaca has mainly erupted dacite, in the form of numerous lava domes, although an andesitic stratovolcano is also present. (Full article...)

A B-52G, similar to the one that crashed at Thule Air Base

On 21 January 1968, an aircraft accident, sometimes known as the Thule affair or Thule accident (/ˈtuːli/; Danish: Thuleulykken), involving a United States Air Force (USAF) B-52 bomber occurred near Thule Air Base in the Danish territory of Greenland. The aircraft was carrying four B28FI thermonuclear bombs on a Cold War "Chrome Dome" alert mission over Baffin Bay when a cabin fire forced the crew to abandon the aircraft before they could carry out an emergency landing at Thule Air Base. Six crew members ejected safely, but one who did not have an ejection seat was killed while trying to bail out. The bomber crashed onto sea ice in North Star Bay, Greenland, causing the conventional explosives aboard to detonate and the nuclear payload to rupture and disperse, resulting in radioactive contamination of the area.

The United States and Denmark launched an intensive clean-up and recovery operation, but the secondary stage of one of the nuclear weapons could not be accounted for after the operation was completed. USAF Strategic Air Command "Chrome Dome" operations were discontinued immediately after the accident, which highlighted the safety and political risks of the missions. Safety procedures were reviewed, and more stable explosives were developed for use in nuclear weapons. (Full article...)

Bristol (/ˈbrɪstəl/ (listen)) is a city, ceremonial county and unitary authority in England. On the River Avon, it is bordered by the ceremonial counties of Gloucestershire to the north and Somerset to the south. It is in the West of England city region and the most populous city in South West England.
The wider Bristol Built-up Area is the eleventh most populous urban area in the United Kingdom.

Iron Age hillforts and Roman villas were built near the confluence of the rivers Frome and Avon. Around the beginning of the 11th century, the settlement was known as Brycgstow (Old English: 'the place at the bridge'). Bristol received a royal charter in 1155 and was historically divided between Gloucestershire and Somerset until 1373 when it became a county corporate. From the 13th to the 18th century, Bristol was among the top three English cities, after London, in tax receipts. (Full article...)

Valley View from the southeast, with Mill Creek Mountain in the background

Valley View is a mid-19th-century Greek Revival residence and farm overlooking the South Branch Potomac River northwest of Romney, West Virginia. The house is atop a promontory where Depot Valley joins the South Branch Potomac River valley.

The Valley View property was part of the South Branch Survey of the Northern Neck Proprietary, a large tract that was inherited by Thomas Fairfax, 6th Lord Fairfax of Cameron, in 1719. It was settled by John Collins and his family in 1749, and acquired by the Parsons family before 1772. The Valley View house was built by James Parsons Jr. in 1855. After the Civil War, Parsons' widow sold the farm to Charles Harmison. His wife, Elizabeth Harmison, inspired by her childhood Virginia home, Western View, and the scenic South Branch Potomac River views, named the farm Valley View. The most recent of a series of owners, the Mayhew family, bought the property in 1979. Valley View's current proprietors, Robert and Kim Mayhew, have restored the historic residence and grounds.

Vital articles to understand Geography.

The marked territories on this global map are mostly of countries which are sovereign states with full international recognition (brackets denote the country of a marked territory that is not a sovereign state). Some territories are countries in their own right but are not recognized as such (e.g. Taiwan), and some few marked territories are disputed about which country they belong to (e.g. Kashmir) or if they are countries in their own right (e.g. Western Sahara (territory) or the state known by the same name).

A country is a distinct part of the world, such as a state, nation, or other political entity. It may be a sovereign state or make up one part of a larger state. For example, the country of Japan is an independent, sovereign state, while the country of Wales is a component of a multi-part sovereign state, the United Kingdom. A country may be a historically sovereign area (such as Korea), a currently sovereign territory with a unified government (such as Senegal), or a non-sovereign geographic region associated with certain distinct political, ethnic, or cultural characteristics (such as the Basque Country).

General Perspective projection
Map: Strebe, using Geocart
The General Perspective projection is a map projection used in cartography in which the Earth is depicted as viewed from a finite distance above its surface. If the view precisely faces the center of the Earth, the projection is a vertical perspective projection; otherwise, it is a tilted perspective projection. Here is shown a vertical perspective from an altitude of 35,786 km over (0°, 90°W), corresponding to a view from geostationary orbit. Due to the horizon as seen from the viewpoint position, the projection always shows less than half of the Earth's surface: in this case neither of the North and South Poles is visible.

Yellowstone National Park
Map credit: Heinrich C. Berann
Yellowstone National Park is an American national park located mostly in Wyoming and extending into Montana and Idaho. It was established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. Yellowstone was the first national park in the U.S. and is also widely held to be the first national park in the world. The park is known for its wildlife and its many geothermal features, especially the Old Faithful geyser, one of its most popular landmarks. It has many types of ecosystems, but the subalpine forest is the most abundant. The park is part of the South Central Rockies forests ecoregion. In 1978, Yellowstone was named a World Heritage Site by UNESCO.

This picture is a stylized panoramic map of Yellowstone National Park as viewed from the northeast, created in 1991 by Austrian painter and cartographer Heinrich C. Berann for the National Park Service. Yellowstone Lake and the Grand Canyon of the Yellowstone are in the center, while Old Faithful is visible on the right, next to a brown building representing the Old Faithful Inn.

Equirectangular projection
Map: Strebe, using Geocart
The equirectangular projection is a simple map projection attributed to Marinus of Tyre, who Ptolemy claims invented the projection about AD 100. The projection maps meridians to vertical straight lines of constant spacing, and circles of latitude to horizontal straight lines of constant spacing. The projection is neither equal area nor conformal. Because of the distortions introduced by this projection, it has few applications beyond base imagery to be reprojected to some more useful projection.

The Mollweide projection is an equal-area, pseudocylindrical map projection generally used for global maps of the world or night sky. The projection was first published by mathematician and astronomer Karl Mollweide of Leipzig in 1805 but reinvented and popularized in 1857 by Jacques Babinet. The projection trades accuracy of angle and shape for accuracy of proportions in area, and as such is used where that property is needed, such as maps depicting global distributions.

Daedongyeojido is a large scale map of Korea produced by Chosun Dynasty cartographer and geologist Kim Jeong-ho in 1861. Considered to mark the zenith of pre-modern Korean cartography, the map consists of 22 separate, foldable booklets, each covering approximately 47 kilometres (29 mi) (north-south) by 31.5 kilometres (19.6 mi) (east-west). Combined, they form a map of Korea that is 6.7 metres (22 ft) wide and 3.8 metres (12 ft) long. Daedongyeojido is praised for precise delineations of mountain ridges, waterways, and transportation routes, as well as its markings for settlements, administrative areas, and cultural sites.

Anning with her dog, Tray, painted before 1842; the hill Golden Cap can be seen in the background

Mary Anning (21 May 1799 – 9 March 1847) was an English fossil collector, dealer, and palaeontologist who became known around the world for the discoveries she made in Jurassic marine fossil beds in the cliffs along the English Channel at Lyme Regis in the county of Dorset in Southwest England. Anning's findings contributed to changes in scientific thinking about prehistoric life and the history of the Earth.

Anning searched for fossils in the area's Blue Lias and Charmouth Mudstone cliffs, particularly during the winter months when landslides exposed new fossils that had to be collected quickly before they were lost to the sea. Her discoveries included the first correctly identified ichthyosaur skeleton when she was twelve years old; the first two nearly complete plesiosaur skeletons; the first pterosaur skeleton located outside Germany; and fish fossils. Her observations played a key role in the discovery that coprolites, known as bezoar stones at the time, were fossilised faeces, and she also discovered that belemnite fossils contained fossilised ink sacs like those of modern cephalopods.
