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...)

José Maria da Silva Paranhos, Viscount of Rio Branco (16 March 1819 – 1 November 1880), was a Brazilian politician, monarchist, diplomat, teacher and journalist. Rio Branco was born in Salvador, in what was then the Captaincy of Bahia, to a wealthy family, but most of the fortune was lost after his parents' deaths early in his childhood. In 1871, Rio Branco became the president of the Council of Ministers (Prime Minister) for the first time. He would become the Council's longest-serving president, and his cabinet the second longest, in Brazilian history. His government was marked by a time of economic prosperity and the enactment of several reforms. The most important of these initiatives was the Law of Free Birth, which granted freeborn status to children born to slave women. Rio Branco led the government that enacted this law, and its passage increased his popularity. His government was plagued by a long crisis with the Catholic Church that resulted from the expulsion of Freemasons from its lay brotherhoods. After more than four years heading the Cabinet, Rio Branco resigned in 1875. Following a long vacation in Europe, his health swiftly declined and he was diagnosed with oral cancer. Rio Branco died in 1880 and was widely mourned throughout the country. He is regarded by most historians as one of Brazil's greatest statesmen.
Rio Branco attended Brazil's Naval School and became a midshipman in 1841. Later that year he was enrolled in the Army's Military Academy, eventually becoming an instructor there. Rather than continue to serve in the military, he became a politician in the Liberal Party. In 1845, he was elected a member of the provincial house of representatives of Rio de Janeiro province, site of the national capital of the same name. Rio Branco rose to power within the province under the tutelage of Aureliano Coutinho, Viscount of Sepetiba—a veteran politician who held tremendous influence over the young and inexperienced Emperor Pedro II. He temporarily abandoned politics after Aureliano Coutinho's fall from grace and the subsequent dissolution of the Liberal Party. (Full article...)
The Battle of Rossbach took place on 5 November 1757 during the Third Silesian War (1756–1763, part of the Seven Years' War) near the village of Rossbach (Roßbach), in the Electorate of Saxony. It is sometimes called the Battle of, or at, Reichardtswerben, after a different nearby town. In this 90-minute battle, Frederick the Great, king of Prussia, defeated an Allied army composed of French forces augmented by a contingent of the Reichsarmee (Imperial Army) of the Holy Roman Empire. The French and Imperial army included 41,110 men, opposing a considerably smaller Prussian force of 22,000. Despite overwhelming odds, Frederick managed to defeat the Imperials and the French.
The Battle of Rossbach marked a turning point in the Seven Years' War, not only for its stunning Prussian victory, but because France refused to send troops against Prussia again and Britain, noting Prussia's military success, increased its financial support for Frederick. Following the battle, Frederick immediately left Rossbach and marched for 13 days to the outskirts of Breslau. There he met the Austrian army at the Battle of Leuthen; he employed similar tactics to again defeat an army considerably larger than his own. (Full article...)
RSPB Dearne Valley Old Moor is an 89-hectare (220-acre) wetlands nature reserve in the Dearne Valley near Barnsley, South Yorkshire, run by the Royal Society for the Protection of Birds (RSPB). It lies on the junction of the A633 and A6195 roads and is bordered by the Trans Pennine Trail long-distance path. Following the end of coal mining locally, the Dearne Valley had become a derelict post-industrial area, and the removal of soil to cover an adjacent polluted site enabled the creation of the wetlands at Old Moor.
Old Moor is managed to benefit bitterns, breeding waders such as lapwings, redshanks and avocets, and wintering golden plovers. A calling male little bittern was present in the summers of 2015 and 2016. (Full article...)
Mount Melbourne is a 2,733-metre-high (8,967 ft) ice-covered stratovolcano in Victoria Land, Antarctica, between Wood Bay and Terra Nova Bay. It is an elongated mountain with a summit caldera filled with ice with numerous parasitic vents; a volcanic field surrounds the edifice. Mount Melbourne has a volume of about 180 cubic kilometres (43 cu mi) and consists of tephra deposits and lava flows; tephra deposits are also found encased within ice and have been used to date the last eruption of Mount Melbourne to 1892 ± 30 years. The volcano is fumarolically active.
The volcano is part of the McMurdo Volcanic Group, and together with The Pleiades, Mount Overlord, Mount Rittmann and the Malta Plateau forms a subprovince, the Melbourne volcanic province. The volcanism is related both to the West Antarctic Rift and to local tectonic structures such as faults and grabens. Mount Melbourne has mainly erupted trachyandesite and trachyte, which formed within a magma chamber; basaltic rocks are less common. (Full article...)
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...)
The Discovery Expedition of 1901–1904, known officially as the British National Antarctic Expedition, was the first official British exploration of the Antarctic regions since the voyage of James Clark Ross sixty years earlier (1839–1843). Organized on a large scale under a joint committee of the Royal Society and the Royal Geographical Society (RGS), the new expedition carried out scientific research and geographical exploration in what was then largely an untouched continent. It launched the Antarctic careers of many who would become leading figures in the Heroic Age of Antarctic Exploration, including Robert Falcon Scott who led the expedition, Ernest Shackleton, Edward Wilson, Frank Wild, Tom Crean and William Lashly.
Its scientific results covered extensive ground in biology, zoology, geology, meteorology and magnetism. The expedition discovered the existence of the only snow-free Antarctic valleys, which contains the longest river of Antarctica. Further achievements included the discoveries of the Cape Crozier emperor penguin colony, King Edward VII Land, and the Polar Plateau (via the western mountains route) on which the South Pole is located. The expedition tried to reach the South Pole travelling as far as the Farthest South mark at a reported 82°17′S. (Full article...)
Northern England, or the North of England, is a region that forms the northern part of England and mainly corresponds to the historic counties of Cheshire, Cumberland, Durham, Lancashire, Northumberland, Westmorland and Yorkshire. The region also coincides with the medieval era borders of Anglian Northumbria, the Anglo-Scandinavian Kingdom of Jorvik, and the Brythonic Celtic Hen Ogledd kingdoms.
The North is a grouping of three statistical regions: the North East, the North West, and Yorkshire and the Humber. These had a combined population of 15.5 million at the 2021 census, an area of 37,331 km (14,414 square miles) and 17 cities. (Full article...)
Chat Moss is a large area of peat bog that makes up part of the City of Salford, Metropolitan Borough of Wigan and Trafford in Greater Manchester, England. It also makes up part of Metropolitan Borough of St Helens in Merseyside and Warrington in Cheshire. North of the Manchester Ship Canal and River Mersey, 5 miles (8 km) to the west of Manchester, it occupies an area of about 10.6 square miles (27.5 km).
As it might be recognised today, Chat Moss is thought to be about 7,000 years old, but peat development seems to have begun there with the ending of the last ice age, about 10,000 years ago. The depth of peat ranges from 24 to 30 feet (7 to 9 m). A great deal of reclamation work has been carried out, particularly during the 19th century, but a large-scale network of drainage channels is still required to keep the land from reverting to bog. In 1958 workers extracting peat discovered the severed head of what is believed to be a Romano-British Celt, possibly a sacrificial victim, in the eastern part of the bog near Worsley.
