P:GEO

Geography (from Ancient Greek γεωγραφία geōgraphía; combining gê 'Earth' and gráphō 'write') 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."

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). This work created the so-called "Ptolemaic tradition" of geography, which included "Ptolemaic cartographic theory." 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 surveying. (Full article...)

Upper Tryon Creek in Marshall Park

Tryon Creek is a 4.85-mile (7.81 km) tributary of the Willamette River in the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its watershed covers about 6.5 square miles (16.8 km²) in Multnomah and Clackamas counties. The stream flows southeast from the Tualatin Mountains (West Hills) through the Multnomah Village neighborhood of Portland and the Tryon Creek State Natural Area to the Willamette in the city of Lake Oswego. Parks and open spaces cover about 21 percent of the watershed, while single-family homes dominate most of the remainder. The largest of the parks is the state natural area, which straddles the border between the two cities and counties.

The bedrock under the watershed includes part of the last exotic terrane, a chain of seamounts, acquired by the North American Plate as it moved west during the Eocene. Known as the Waverly Hills Formation, it lies buried under ash and lava from later volcanic eruptions, sediments from flooding and erosion, and layers of wind-blown silt. Two dormant volcanoes from the Boring Lava Field are in the Tryon Creek watershed. (Full article...)

A series of small volcanic earthquakes measuring less than 4.0 on the Richter magnitude scale took place in the sparsely populated Nazko area of the Central Interior of British Columbia, Canada, from October 9, 2007, to June 12, 2008. They occurred just west of Nazko Cone, a small tree-covered cinder cone that last erupted about 7,200 years ago.

No damage or casualties resulted from the Nazko earthquakes, which were too small to be felt by people, but local seismographs recorded them. The earthquake swarm occurred at the eastern end of a known volcanic zone called the Anahim Volcanic Belt. This is an east–west trending line of volcanic formations extending from the Central Coast to the Central Interior of British Columbia. (Full article...)

SY Aurora, anchored to the Antarctic ice

The drift of the Antarctic exploration vessel SY Aurora was an ordeal which lasted 312 days, affecting the Ross Sea party of Sir Ernest Shackleton's Imperial Trans-Antarctic Expedition, 1914–1917. It began when the ship broke loose from its anchorage in McMurdo Sound in May 1915, during a gale. Caught in heavy pack ice and unable to manoeuvre, Aurora, with eighteen men aboard, was carried into the open waters of the Ross Sea and Southern Ocean, leaving ten men stranded ashore with meagre provisions.

Aurora, a 40-year-old former Arctic whaler registered as a steam yacht, had brought the Ross Sea party to Cape Evans in McMurdo Sound in January 1915, to establish its base there in support of Shackleton's proposed transcontinental crossing. When Aurora's captain Aeneas Mackintosh took charge of activities ashore, first officer Joseph Stenhouse assumed command of the ship. Stenhouse's inexperience may have contributed to the choice of an inappropriate winter's berth, although his options were restricted by the instructions of his superiors. After the ship was blown away it suffered severe damage in the ice, including the destruction of its rudder and the loss of its anchors; on several occasions its situation was such that Stenhouse considered abandonment. Efforts to make wireless contact with Cape Evans and, later, with stations in New Zealand and Australia, were unavailing; the drift extended through the southern winter and spring to reach a position north of the Antarctic Circle. In February 1916 the ice broke up, and a month later the ship was free. It was subsequently able to reach New Zealand for repairs and resupply, before returning to Antarctica to rescue the seven surviving members of the shore party. (Full article...)

There are 24 named waterfalls in Ricketts Glen State Park in the U.S. state of Pennsylvania along Kitchen Creek as it flows in three steep, narrow valleys, or glens. They range in height from 9 feet (2.7 m) to the 94-foot (29 m) Ganoga Falls. Ricketts Glen State Park is named for R. Bruce Ricketts, a colonel in the American Civil War who owned over 80,000 acres (32,000 hectares) in the area in the late 19th and early 20th centuries, but spared the old-growth forests in the glens from clearcutting. The park, which opened in 1944, is administered by the Bureau of State Parks of the Pennsylvania Department of Conservation and Natural Resources (DCNR). Nearly all of the waterfalls are visible from the Falls Trail, which Ricketts had built from 1889 to 1893 and which the state park rebuilt in the 1940s and late 1990s. The Falls Trail has been called "the most magnificent hike in the state" and one of "the top hikes in the East". (Full article...)

Skyline of the city centre

George Town is the capital of the Malaysian state of Penang. It is the core city of the George Town Conurbation, Malaysia's second largest metropolitan area with a population of 2.84 million and the second highest contributor to the country's GDP. The city proper spans an area of 306 km² (118 sq mi) encompassing Penang Island and surrounding islets, and had a population of 794,313 as of 2020^[update].

Initially established as an entrepôt by Francis Light in 1786, George Town serves as the commercial centre for northern Malaysia. According to Euromonitor International and the Economist Intelligence Unit, it has the highest potential for revenue growth among all Malaysian cities and contributed nearly 8 per cent of the country's personal disposable income in 2015, second only to the national capital, Kuala Lumpur. Its technological sector, anchored by hundreds of multinational companies, has made George Town the top exporter in the country. The Penang International Airport links George Town to several regional cities, while a ferry service and two road bridges connect the city to the rest of Peninsular Malaysia. Swettenham Pier is the busiest cruise terminal in the country. (Full article...)

The main hut at Cape Denison

The Australasian Antarctic Expedition was a 1911–1914 expedition headed by Douglas Mawson that explored the largely uncharted Antarctic coast due south of Australia. Mawson had been inspired to lead his own venture by his experiences on Ernest Shackleton's Nimrod expedition in 1907–1909. During its time in Antarctica, the expedition's sledging parties covered around 4,180 kilometres (2,600 mi) of unexplored territory, while its ship, SY Aurora, navigated 2,900 kilometres (1,800 mi) of unmapped coastline. Scientific activities included meteorological measurements, magnetic observations, an expansive oceanographic program, and the collection of many biological and geological samples, including the discovery of the first meteorite found in Antarctica. The expedition was the first to establish and maintain wireless contact between Antarctica and Australia. Another planned innovation – the use of an aircraft – was thwarted by an accident before the expedition sailed. The plane's fuselage was adapted to form a motorised sledge or "air-tractor", but it proved to be of very limited usefulness.

The expedition was organised into three bases: one on the sub-Antarctic Macquarie Island and two on the Antarctic mainland. The main base, under Mawson's command, was set up at Cape Denison, about 500 kilometres (300 mi) west of Cape Adare, and a western base under Frank Wild was established on the Shackleton Ice Shelf, more than 2,400 kilometres (1,500 mi) west of Cape Denison. Activities at both mainland bases were hampered by extreme winds, which often made outside work impossible. (Full article...)

Photo of McNish cropped from the 1914–1917 Imperial Trans-Antarctic Expedition crew photo.

Henry McNish (11 September 1874 – 24 September 1930), often referred to as Harry McNish or by the nickname Chippy, was the carpenter on Sir Ernest Shackleton's Imperial Trans-Antarctic Expedition of 1914–1917. He was responsible for much of the work that ensured the crew's survival after their ship, the Endurance, was destroyed when it became trapped in pack ice in the Weddell Sea. He modified the small boat, James Caird, that allowed Shackleton and five men (including McNish) to make a voyage of hundreds of miles to fetch help for the rest of the crew.

After the expedition he returned to work in the Merchant Navy and eventually emigrated to New Zealand, where he worked on the docks in Wellington until poor health forced his retirement. He died destitute in the Ohiro Benevolent Home in Wellington. (Full article...)

Caxias in 1878

Luís Alves de Lima e Silva, Duke of Caxias (pronounced [kaˈʃi.ɐs]; 25 August 1803 – 7 May 1880), nicknamed "the Peacemaker" and "the Iron Duke", was an army officer, politician and monarchist of the Empire of Brazil. Like his father and uncles, Caxias pursued a military career. In 1823 he fought as a young officer in the Brazilian War for Independence against Portugal, then spent three years in Brazil's southernmost province, Cisplatina, as the government unsuccessfully resisted that province's secession in the Cisplatine War. Though his own father and uncles renounced Emperor Dom Pedro I during the protests of 1831, Caxias remained loyal. Pedro I abdicated in favor of his young son Dom Pedro II, whom Caxias instructed in swordsmanship and horsemanship and eventually befriended.

During Pedro II's minority the governing regency faced countless rebellions throughout the country. Again breaking with his father and other relatives sympathetic to the rebels, from 1839 to 1845 Caxias commanded loyalist forces suppressing such uprisings as the Balaiada, the Liberal rebellions of 1842 and the Ragamuffin War. In 1851, under his command, the Brazilian army prevailed against the Argentine Confederation in the Platine War; a decade later Caxias, as army marshal (the army's highest rank), led Brazilian forces to victory in the Paraguayan War. As a reward he was raised to the titled nobility, becoming successively a baron, count, and marquis, finally becoming the only person created duke during Pedro II's 58-year reign. (Full article...)

Storming of the breach by Prussian grenadiers, Carl Röchling

The Battle of Leuthen /ˈlɔɪtən/ was fought on 5 December 1757 between Frederick the Great's Prussian Army and an Austrian army commanded by Prince Charles of Lorraine and Count Leopold Joseph von Daun. Frederick used maneuver warfare and knowledge of the terrain to rout the larger Austrian force completely. The victory ensured Prussian control of Silesia during the Third Silesian War, which was part of the Seven Years' War.

The battle was fought in the town of Leuthen (now Lutynia, Poland), 10 km (6 mi) northwest of Breslau, (now Wrocław, Poland), in Prussian (formerly Austrian) Silesia. By exploiting the training of his troops and his superior knowledge of the terrain, Frederick created a diversion at one end of the battlefield and moved most of his smaller army behind a series of low hillocks. The surprise attack in oblique order on the unsuspecting Austrian flank baffled Prince Charles, who took several hours to realize that the main action was to his left, not his right. Within seven hours, the Prussians had destroyed the Austrians and erased any advantage that the Austrians had gained throughout the campaigning in the preceding summer and autumn. Within 48 hours, Frederick had laid siege to Breslau, which resulted in the city's surrender on 19–20 December. (Full article...)

Atlantic Ocean near the Faroe Islands

A sea is a large body of salt water. There are particular seas and the sea. The sea commonly refers to the Ocean, the interconnected body of seawaters that spans most of Earth.
Particular seas are either marginal seas, second-order sections of the oceanic sea (e.g. the Mediterranean Sea), or certain large, nearly landlocked bodies of water.

The salinity of water bodies varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary little across the oceans. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. A wide variety of organisms, including bacteria, protists, algae, plants, fungi, and animals live in the seas, which offers a wide range of marine habitats and ecosystems, ranging vertically from the sunlit surface and shoreline to the great depths and pressures of the cold, dark abyssal zone, and in latitude from the cold waters under polar ice caps to the warm waters of coral reefs in tropical regions. Many of the major groups of organisms evolved in the sea and life may have started there. (Full article...)

Column of Armenian deportees guarded by gendarmes in Harput vilayet

The Armenian genocide was the systematic destruction of the Armenian people and identity in the Ottoman Empire during World War I. Spearheaded by the ruling Committee of Union and Progress (CUP), it was implemented primarily through the mass murder of around one million Armenians during death marches to the Syrian Desert and the forced Islamization of others, primarily women and children.

Before World War I, Armenians occupied a somewhat protected, but subordinate, place in Ottoman society. Large-scale massacres of Armenians had occurred in the 1890s and 1909. The Ottoman Empire suffered a series of military defeats and territorial losses—especially during the 1912–1913 Balkan Wars—leading to fear among CUP leaders that the Armenians would seek independence. During their invasion of Russian and Persian territory in 1914, Ottoman paramilitaries massacred local Armenians. Ottoman leaders took isolated instances of Armenian resistance as evidence of a widespread rebellion, though no such rebellion existed. Mass deportation was intended to permanently forestall the possibility of Armenian autonomy or independence. (Full article...)

The canal at Bathampton, near Bath

The Kennet and Avon Canal is a waterway in southern England with an overall length of 87 miles (140 km), made up of two lengths of navigable river linked by a canal. The name is used to refer to the entire length of the navigation rather than solely to the central canal section. From Bristol to Bath the waterway follows the natural course of the River Avon before the canal links it to the River Kennet at Newbury, and from there to Reading on the River Thames. In all, the waterway incorporates 105 locks.

The two river stretches were made navigable in the early 18th century, and the 57-mile (92 km) canal section was constructed between 1794 and 1810. In the late 19th and early 20th centuries, the canal gradually fell into disuse after the opening of the Great Western Railway. In the latter half of the 20th century the canal was restored in stages, largely by volunteers. After decades of dereliction and much restoration work, it was fully reopened in 1990. The Kennet and Avon Canal has been developed as a popular heritage tourism destination for boating, canoeing, fishing, walking and cycling, and is also important for wildlife conservation.

Trafford Town Hall

Trafford is a metropolitan borough of Greater Manchester, England, with an estimated population of 236,301 in 2022. It covers 106 square kilometres (41 sq mi) and includes the area of Old Trafford and the towns of Altrincham, Stretford, Urmston, Partington and Sale. The borough was formed in 1974 as a merger of six former districts and part of a seventh. The River Mersey flows through the borough, separating North Trafford from South Trafford, and the historic counties of Lancashire and Cheshire. Trafford is the seventh-most populous district in Greater Manchester.

There is evidence of Neolithic, Bronze Age, and Roman activity in the area, two castles – one of them a Scheduled Ancient Monument – and over 200 listed buildings. In the late 19th century, the population rapidly expanded with the arrival of the railway. Trafford is the home of Manchester United F.C. and Lancashire County Cricket Club, as well as Altrincham F.C. and Trafford F.C.. The Imperial War Museum North, opened in 2002, is located in the borough. (Full article...)

Newberry Caldera, with Paulina Lake, East Lake, and Big Obsidian Flow.

Newberry Volcano is a large, active, shield-shaped stratovolcano located about 20 miles (32 km) south of Bend, Oregon, United States, 35 miles (56 km) east of the major crest of the Cascade Range, within the Newberry National Volcanic Monument. Its highest point is Paulina Peak. Newberry is the largest volcano in the Cascade Volcanic Arc, with an area of 1,200 square miles (3,100 km²) when its lava flows are taken into account. From north to south, the volcano has a length of 75 miles (121 km), with a width of 27 miles (43 km) and a total volume of approximately 120 cubic miles (500 km³). It was named for the geologist and surgeon John Strong Newberry, who explored central Oregon for the Pacific Railroad Surveys in 1855.

The volcano contains a large caldera, 4 by 5 miles (6.4 km × 8.0 km) in diameter, known as the Newberry Caldera. Within the caldera are two lakes: Paulina Lake and East Lake. The volcano and its vicinity include many pyroclastic cones, lava flows and lava domes; Newberry has more than 400 vents, the most of any volcano in the contiguous United States. Glaciers may have once been present at the volcano, though this remains contested. The area has a dry climate with low precipitation levels and little surface runoff. (Full article...)

Hoodoo Mountain as seen from the Iskut River

Hoodoo Mountain, sometimes referred to as Hoodoo Volcano, is a potentially active stratovolcano in the Northern Interior of British Columbia, Canada. It is located 25 kilometres (16 miles) northeast of the Alaska–British Columbia border on the north side of the Iskut River opposite of the mouth of the Craig River. With a summit elevation of 1,850 metres (6,070 feet) and a topographic prominence of 900 metres (3,000 feet), Hoodoo Mountain is one of many prominent peaks within the Boundary Ranges of the Coast Mountains. Its flat-topped summit is covered by an ice cap more than 100 metres (330 feet) thick and at least 3 kilometres (1.9 miles) in diameter. Two valley glaciers surrounding the northwestern and northeastern sides of the mountain have retreated significantly over the last hundred years. They both originate from a large icefield to the north and are the sources of two meltwater streams. These streams flow along the western and eastern sides of the volcano before draining into the Iskut River.

Much of Hoodoo Mountain was formed beneath glacial ice and it has been overlain by glaciers or an ice cap throughout much of its history. The main rock types composing the volcano are phonolite and trachyte, which were deposited during six periods of eruptive activity beginning about 85,000 years ago. Most of these eruptive periods were characterized by steady flows of lava but at least one period of explosive activity occurred as indicated by the presence of pyroclastic rocks. The latest eruptive period began about 10,000 years ago with the eruption of extensive lava flows that cover the north–central, northwestern and southeastern mountain slopes. A lava flow covering the southwestern slope may have been produced by a more recent eruption within the last couple of hundred years. Although no historical eruptions are known at Hoodoo Mountain, there have been periods of seismic activity since at least the mid-1980s, indicating possible future eruptions and volcanic hazards.

Vital articles to understand Geography.

A country is a distinct part of the world, such as a state, nation, or other political entity. When referring to a specific polity, the term "country" may refer to a sovereign state, states with limited recognition, constituent country, or a dependent territory. Most sovereign states, but not all countries, are members of the United Nations. There is no universal agreement on the number of "countries" in the world since several states have disputed sovereignty status, limited recognition and a number of non-sovereign entities are commonly considered countries.

Craig retroazimuthal projection
Map: Strebe, using Geocart
The Craig retroazimuthal is a modified cylindrical map projection created by James Ireland Craig in 1909. It preserves the direction from any place to one other, predetermined place while avoiding some of the distortion of the Hammer retroazimuthal projection. This projection is sometimes known as the Mecca projection because Craig, who had worked in Egypt as a cartographer, created it to help Muslims find the qibla.

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.

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.

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.
