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...)
Manchester (/ˈmæntʃɪstər, -tʃɛs-/ ) is a city and metropolitan borough of Greater Manchester, England, which had an estimated population of 568,996 in 2022. It contributes to the third-most populous metropolitan area in the United Kingdom as a part of Greater Manchester, which has a population of approximately 2.92 million. It is bordered by the Cheshire Plain to the south, the Pennines to the north and east, and the neighbouring city of Salford to the west. The city borders the boroughs of Trafford, Stockport, Tameside, Oldham, Rochdale, Bury and Salford.
The history of Manchester began with the civilian settlement associated with the Roman fort (castra) of Mamucium or Mancunium, established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Throughout the Middle Ages, Manchester remained a manorial township but began to expand "at an astonishing rate" around the turn of the 19th century. Manchester's unplanned urbanisation was brought on by a boom in textile manufacture during the Industrial Revolution and resulted in it becoming the world's first industrialised city. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century, including Wythenshawe in 1931. Manchester achieved city status in 1853. The Manchester Ship Canal opened in 1894, creating the Port of Manchester and linking the city to the Irish Sea, 36 miles (58 km) to the west. The city's fortune declined after the Second World War, owing to deindustrialisation, and the IRA bombing in 1996 led to extensive investment and regeneration. Following considerable redevelopment, Manchester was the host city for the 2002 Commonwealth Games. (Full article...)
The Maya civilization (/ˈmaɪə/) was a Mesoamerican civilization that existed from antiquity to the early modern period. It is known by its ancient temples and glyphs (script). The Maya script is the most sophisticated and highly developed writing system in the pre-Columbian Americas. The civilization is also noted for its art, architecture, mathematics, calendar, and astronomical system.
The Maya civilization developed in the Maya Region, an area that today comprises southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. It includes the northern lowlands of the Yucatán Peninsula and the Guatemalan Highlands of the Sierra Madre, the Mexican state of Chiapas, southern Guatemala, El Salvador, and the southern lowlands of the Pacific littoral plain. Today, their descendants, known collectively as the Maya, number well over 6 million individuals, speak more than twenty-eight surviving Mayan languages, and reside in nearly the same area as their ancestors.

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 just over 41 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.

Because of the high risk of extinction for island fauna and the decline in coral reef ecosystems, Seacology's primary focus is projects in which villagers sign contracts under which they agree to help protect either terrestrial or marine habitat for a specified time in return for new buildings or services. The operations are low-cost, averaging around US$20,000 to $25,000. Construction is done with local labor and sometimes without the use of machinery. Seacology selects its projects by reviewing the recommendations of its field representatives and its scientific advisory board. (Full article...)
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 (500 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 disproven 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 line 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 implausibility. (Full article...)
The Armero tragedy (Spanish: Tragedia de Armero [tɾaˈxeðja ðe aɾˈmeɾo]) occurred following the eruption of the Nevado del Ruiz stratovolcano in Tolima, Colombia, on November 13, 1985. The volcano's eruption after 69 years of dormancy caught nearby towns unprepared, even though volcanological organizations had warned the government to evacuate the area after they detected volcanic activity two months earlier.
As pyroclastic flows erupted from the volcano's crater, they melted the mountain's glaciers, sending four enormous lahars (volcanically induced mudflows, landslides, and debris flows) down its slopes at 50 km/h (30 mph). The lahars picked up speed in gullies and engulfed the town of Armero, killing more than 20,000 of its almost 29,000 inhabitants. Casualties in other towns, particularly Chinchiná, brought the overall death toll to 23,000. Footage and photographs of Omayra Sánchez, a young victim of the disaster, were published around the world. Other photographs of the lahars and the impact of the disaster captured attention worldwide and led to controversy over the degree to which the Colombian government was responsible for the disaster. A banner at a mass funeral in Ibagué read, "The volcano didn't kill 22,000 people. The government killed them." (Full article...)
Joaquim José Inácio, Viscount of Inhaúma (Portuguese: [iɲaˈũmɐ]; 1 August 1808 – 8 March 1869), was a naval officer, politician and monarchist of the Empire of Brazil. He was born in the Kingdom of Portugal, and his family moved to Brazil two years later. After Brazilian independence in 1822, Inhaúma enlisted in the Brazilian navy. Early in his career during the latter half of the 1820s, he participated in the subduing of secessionist rebellions: first the Confederation of the Equator, and then the Cisplatine War, which precipitated a long international armed conflict with the United Provinces of the Río de la Plata.
Throughout the chaos that characterized the years when Emperor Dom Pedro II was a minor, Inhaúma remained loyal to the government. He helped quell a military mutiny in 1831 and was involved in suppressing some of the other rebellions that erupted during that troubled period. He saw action in the Sabinada between 1837 and 1838, followed by the Ragamuffin War from 1840 until 1844. In 1849, after spending two years in Great Britain, Inhaúma was given command of the fleet that was instrumental in subduing the Praieira revolt, the last rebellion in imperial Brazil.

Ambohimanga is a hill and traditional fortified royal settlement (rova) in Madagascar, located approximately 24 kilometers (15 mi) northeast of the capital city of Antananarivo. It is situated in the commune of Ambohimanga Rova.
The hill and the rova that stands on top are considered the most significant symbol of the cultural identity of the Merina people and the most important and best-preserved monument of the precolonial Merina Kingdom. The walled historic village includes residences and burial sites of several key monarchs. The site, one of the twelve sacred hills of Imerina, is associated with strong feelings of national identity and has maintained its spiritual and sacred character both in ritual practice and the popular imagination for at least four hundred years. It remains a place of worship to which pilgrims come from Madagascar and elsewhere. (Full article...)
The peregrine falcon (Falco peregrinus), also known simply as the peregrine, and historically as the duck hawk in North America, is a cosmopolitan bird of prey (raptor) in the family Falconidae. A large, crow-sized falcon, it has a blue-grey back, barred white underparts, and a black head. The peregrine is renowned for its speed. It can reach over 320 km/h (200 mph) during its characteristic hunting stoop (high-speed dive), making it the fastest animal on the planet. According to a National Geographic TV program, the highest measured speed of a peregrine falcon is 389 km/h (242 mph). As is typical for bird-eating (avivore) raptors, peregrine falcons are sexually dimorphic, with females being considerably larger than males.
The peregrine's breeding range includes land regions from the Arctic tundra to the tropics. It can be found nearly everywhere on Earth, except extreme polar regions, very high mountains, and most tropical rainforests; the only major ice-free landmass from which it is entirely absent is New Zealand. This makes it the world's most widespread raptor and one of the most widely found wild bird species. In fact, the only land-based bird species found over a larger geographic area owes its success to human-led introduction; the domestic and feral pigeons are both domesticate forms of the rock dove, which are a major prey species for Eurasian Peregrine populations. Due to their prevalence over most other bird species in cities, feral pigeons support many peregrine populations as a staple food source, especially in urban settings. (Full article...)
Blakeney Point (designated as Blakeney National Nature Reserve) is a national nature reserve situated near to the villages of Blakeney, Morston and Cley next the Sea on the north coast of Norfolk, England. Its main feature is a 6.4 km (4.0 mi) spit of shingle and sand dunes, but the reserve also includes salt marshes, tidal mudflats and reclaimed farmland. It has been managed by the National Trust since 1912, and lies within the North Norfolk Coast Site of Special Scientific Interest, which is additionally protected through Natura 2000, Special Protection Area (SPA), International Union for Conservation of Nature (IUCN) and Ramsar listings. The reserve is part of both an Area of Outstanding Natural Beauty (AONB), and a World Biosphere Reserve. The Point has been studied for more than a century, following pioneering ecological studies by botanist Francis Wall Oliver and a bird ringing programme initiated by ornithologist Emma Turner.
The area has a long history of human occupation; ruins of a medieval monastery and "Blakeney Chapel" (probably a domestic dwelling) are buried in the marshes. The towns sheltered by the shingle spit were once important harbours, but land reclamation schemes starting in the 17th century resulted in the silting up of the river channels. The reserve is important for breeding birds, especially terns, and its location makes it a major site for migrating birds in autumn. Up to 500 seals may gather at the end of the spit, and its sand and shingle hold a number of specialised invertebrates and plants, including the edible samphire, or "sea asparagus". (Full article...)
