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...)

The Riverina (/ˌrɪvəˈriːnə/)
is an agricultural region of southwestern New South Wales, Australia. The Riverina is distinguished from other Australian regions by the combination of flat plains, warm to hot climate and an ample supply of water for irrigation. This combination has allowed the Riverina to develop into one of the most productive and agriculturally diverse areas of Australia. Bordered on the south by the state of Victoria and on the east by the Great Dividing Range, the Riverina covers those areas of New South Wales in the Murray and Murrumbidgee drainage zones to their confluence in the west.
Home to Aboriginal groups including the Wiradjuri people for over 40,000 years, the Riverina was colonised by Europeans in the mid-19th century as a pastoral region providing beef and wool to markets in Australia and beyond. In the 20th century, the development of major irrigation areas in the Murray and Murrumbidgee valleys has led to the introduction of crops such as rice and wine grapes. The Riverina has strong cultural ties to Victoria, and the region was the source of much of the impetus behind the federation of Australian colonies. (Full article...)
The Kingdom of Mysore was a geopolitical realm in southern India founded in around 1399 in the vicinity of the modern-day city of Mysore and prevailed until 1950. The territorial boundaries and the form of government transmuted substantially throughout the kingdom's lifetime. While originally a feudal vassal under the Vijayanagara Empire, it became a princely state in British Raj from 1799 to 1947, marked in-between by major political changes.
The kingdom, which was founded and ruled for the most part by the Wadiyars, initially served as a feudal vassal under the Vijayanagara Empire. With the gradual decline of the Empire, the 16th-century Timmaraja Wodeyar II declared independence from it. The 17th century saw a steady expansion of its territory and, during the rules of Narasaraja Wodeyar I and Devaraja Wodeyar II, the kingdom annexed large expanses of what is now southern Karnataka and parts of Tamil Nadu, becoming a formidable power in the Deccan.

Chartwell is a country house near Westerham, Kent, in South East England. For over forty years it was the home of Sir Winston Churchill. He bought the property in September 1922 and lived there until shortly before his death in January 1965. In the 1930s, when Churchill was out of political office, Chartwell became the centre of his world. At his dining table, he gathered those who could assist his campaign against German re-armament and the British government's response of appeasement; in his study, he composed speeches and wrote books; in his garden, he built walls, constructed lakes and painted. During the Second World War, Chartwell was largely unused, the Churchills returning after he lost the 1945 election. In 1953, when again prime minister, the house became Churchill's refuge when he suffered a debilitating stroke. In October 1964, he left for the last time, dying at his London home, 28 Hyde Park Gate, on 24 January 1965.
The origins of the estate reach back to the 14th century; in 1382, the property then called Well-street was owned by William-at-Well. It passed through various owners and in 1836 was auctioned, as a substantial brick-built manor. In 1848, it was purchased by John Campbell Colquhoun, whose grandson sold it to Churchill. The Campbell Colquhouns greatly enlarged the house and the advertisement for its sale at the time of Churchill's purchase described it as an imposing mansion. Between 1922 and 1924, it was rebuilt and extended by the society architect Philip Tilden. From the garden front, the house has extensive views over the Weald of Kent, "the most beautiful and charming" Churchill had ever seen, and the determining factor in his decision to buy the house.

Henry IV (German: Heinrich IV; 11 November 1050 – 7 August 1106) was Holy Roman Emperor from 1084 to 1105, King of Germany from 1054 to 1105, King of Italy and Burgundy from 1056 to 1105, and Duke of Bavaria from 1052 to 1054. He was the son of Henry III, Holy Roman Emperor—the second monarch of the Salian dynasty—and Agnes of Poitou. After his father's death on 5 October 1056, Henry was placed under his mother's guardianship. She made grants to German aristocrats to secure their support. Unlike her late husband, she could not control the election of the popes, thus the idea of the "liberty of the Church" strengthened during her rule. Taking advantage of her weakness, Archbishop Anno II of Cologne kidnapped Henry in April 1062. He administered Germany until Henry came of age in 1065.
Henry endeavoured to recover the royal estates that had been lost during his minority. He employed low-ranking officials to carry out his new policies, causing discontent in Saxony and Thuringia. Henry crushed a riot in Saxony in 1069 and overcame the rebellion of the Saxon aristocrat Otto of Nordheim in 1071. The appointment of commoners to high office offended German aristocrats, and many of them withdrew from Henry's court. He insisted on his royal prerogative to appoint bishops and abbots, although the reformist clerics condemned this practice as simony (a forbidden sale of church offices). Pope Alexander II blamed Henry's advisors for his acts and excommunicated them in early 1073. Henry's conflicts with the Holy See and the German dukes weakened his position and the Saxons rose up in open rebellion in the summer of 1074. Taking advantage of a quarrel between the Saxon aristocrats and peasantry, he forced the rebels into submission in October 1075. (Full article...)
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...)
The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, it is found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
Orcas are apex predators with a diverse diet. Individual populations often specialize in particular types of prey. This includes a variety of fish, sharks, rays, and marine mammals such as seals and other dolphins and whales. They are highly social; some populations are composed of highly stable matrilineal family groups (pods). Their sophisticated hunting techniques and vocal behaviors, often specific to a particular group and passed along from generation to generation, are considered to be manifestations of animal culture.

Plymouth Colony (sometimes Plimouth) was the first permanent English colony in New England from 1620 and the third permanent English colony in America, after Newfoundland and the Jamestown Colony. It was settled by the passengers on the Mayflower at a location that had previously been surveyed and named by Captain John Smith. The settlement served as the capital of the colony and developed as the town of Plymouth, Massachusetts. At its height, Plymouth Colony occupied most of what is now the southeastern portion of Massachusetts. Many of the people and events surrounding Plymouth Colony have become part of American folklore, including the American tradition of Thanksgiving and the monument of Plymouth Rock.
Plymouth Colony was founded by a group of Protestant Separatists initially known as the Brownist Emigration, who came to be known as the Pilgrims. The colony established a treaty with Wampanoag Chief Massasoit which helped to ensure its success; in this, they were aided by Squanto, a member of the Patuxet tribe. Plymouth played a central role in King Philip's War (1675–1678), one of several Indian Wars, but the colony was ultimately merged with the Massachusetts Bay Colony and other territories in 1691 to form the Province of Massachusetts Bay.

Caroline Island (also known as Caroline Atoll or Millennium Island) is the easternmost of several uninhabited coral atolls comprising the southern Line Islands in the central Pacific Ocean nation of Kiribati.
The atoll was first sighted by Europeans in 1606 and was claimed by the United Kingdom of Great Britain and Ireland in 1868. It has been part of the Republic of Kiribati since the island nation's independence in 1979. Caroline Island has remained relatively untouched and is one of the world's most pristine tropical islands, despite guano mining, copra (coconut meat) harvesting, and human habitation in the 19th and 20th centuries. It is home to one of the world's largest populations of the coconut crab and is an important breeding site for seabirds, most notably the sooty tern. (Full article...)
Balch Creek is a 3.5-mile (5.6 km) tributary of the Willamette River in the U.S. state of Oregon. Beginning at the crest of the Tualatin Mountains (West Hills), the creek flows generally east down a canyon along Northwest Cornell Road in unincorporated Multnomah County and through the Macleay Park section of Forest Park, a large municipal park in Portland. At the lower end of the park, the stream enters a pipe and remains underground until reaching the river. Danford Balch, after whom the creek is named, settled a land claim along the creek in the mid-19th century. After murdering his son-in-law, he became the first person legally hanged in Oregon.
Basalt, mostly covered by silt in the uplands and sediment in the lowlands, underlies the Balch Creek watershed. The upper part of the watershed includes private residential land, the Audubon Society of Portland nature sanctuary, and part of Forest Park. Mixed conifer forest of Coast Douglas-fir, western redcedar, and western hemlock with a well-developed understory of shrubs and flowering plants is the natural vegetation. Sixty-two species of mammals and more than 112 species of birds use Forest Park. A small population of coastal cutthroat trout resides in the stream, which in 2005 was the only major water body in Portland that met state standards for bacteria, temperature, and dissolved oxygen.

Mount Takahe is a 3,460-metre-high (11,350 ft) snow-covered shield volcano in Marie Byrd Land, Antarctica, 200 kilometres (120 mi) from the Amundsen Sea. It is a c. 30-kilometre-wide (19 mi) mountain with parasitic vents and a caldera up to 8 kilometres (5 mi) wide. Most of the volcano is formed by trachytic lava flows, but hyaloclastite is also found. Snow, ice, and glaciers cover most of Mount Takahe. With a volume of 780 km (200 cu mi), it is a massive volcano; the parts of the edifice that are buried underneath the West Antarctic Ice Sheet are probably even larger. It is part of the West Antarctic Rift System along with 18 other known volcanoes.
The volcano was active in the Quaternary period. Radiometric dating has yielded ages of up to 300,000 years for its rocks, and it reached its present height about 200,000 years ago. Several tephra layers encountered in ice cores at Mount Waesche and Byrd Station have been attributed to Mount Takahe, although some of them were later linked to eruptions of Mount Berlin instead. The tephra layers were formed by explosive or phreatomagmatic eruptions. Major eruptions took place around 17,700 years ago—possibly forming an ozone hole over Antarctica—and in the early Holocene. Mount Takahe's last eruption occurred about 7,600 years ago, and there is no present-day activity. (Full article...)

John William Beschter SJ (born Johann Wilhelm Beschter; German: [ˈjoːhan ˈvɪlhɛlm ˈbɛʃtɐ]; May 20, 1763 – January 6, 1842) was a Catholic priest and Jesuit from the Duchy of Luxembourg in the Austrian Netherlands. He emigrated to the United States as a missionary in 1807, where he ministered in rural Pennsylvania and Maryland. Beschter was the last Jesuit pastor of St. Mary's Church in Lancaster, as well as the pastor of St. John the Evangelist Church in Baltimore, Maryland. He was also a priest at several other German-speaking churches in Pennsylvania.
Beschter's ministerial work was punctuated by a time as master of novices at the new Jesuit novitiate at White Marsh Manor, as well as a brief term as president of Georgetown College in 1829. While in Maryland, he aligned himself with the Continental European Jesuits in the United States, who endorsed a monarchist view of ecclesiastical leadership. After his presidency, Beschter remained at Georgetown for a year as a professor of German, before returning to Paradise, Pennsylvania, where he lived out the last twelve years of his life as a priest.

Armenian genocide denial is the negationist claim that the Ottoman Empire and its ruling party, the Committee of Union and Progress (CUP), did not commit genocide against its Armenian citizens during World War I—a crime documented in a large body of evidence and affirmed by the vast majority of scholars. The perpetrators denied the genocide as they carried it out, claiming that Armenians in the Ottoman Empire were resettled for military reasons, not exterminated. In its aftermath, incriminating documents were systematically destroyed. Denial has been the policy of every government of the Ottoman Empire's successor state, the Republic of Turkey, as of 2024.
Borrowing arguments used by the CUP to justify its actions, Armenian genocide denial rests on the assumption that the deportation of Armenians was a legitimate state action in response to a real or perceived Armenian uprising that threatened the empire's existence during wartime. Deniers assert the CUP intended to resettle Armenians, not kill them. They claim the death toll is exaggerated or attribute the deaths to other factors, such as a purported civil war, disease, bad weather, rogue local officials, or bands of Kurds and outlaws. The historian Ronald Grigor Suny summarizes the main argument as "there was no genocide, and the Armenians were to blame for it". (Full article...)
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...)
Socompa is a large stratovolcano (composite volcano) on the border of Argentina and Chile. It has an elevation of 6,051 metres (19,852 ft) and is part of the Chilean and Argentine Andean Volcanic Belt (AVB). Socompa is within the Central Volcanic Zone, one of the segments of the AVB, which contains about 44 active volcanoes. It begins in Peru and runs first through Bolivia and Chile, and then Argentina and Chile. Socompa lies close to the pass of the same name where the Salta-Antofagasta railway crosses the Chilian border.
Most of the northwestern slope of Socompa collapsed catastrophically 7,200 years ago to form an extensive debris avalanche deposit. The Socompa collapse is among the largest known on land with a volume of 19.2 cubic kilometres (4.6 cu mi) and a surface area of 490 square kilometres (190 sq mi); its features are well-preserved by the arid climate. The deposit was at first considered to be either a moraine or a pyroclastic flow deposit, until the 1980 eruption of Mount St. Helens prompted awareness of the instability of volcanic edifices and the existence of large-scale collapses. There are large toreva blocks, which were left behind within the collapse crater. After the landslide, the volcano was rebuilt by the effusion of lava flows and much of the scar is now filled in.
