Geography (from Ancient Greekγεωγραφίαgeōgraphía; 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...)
In the aftermath of emperor Pedro I's abdication in 1831, a regency created to govern Brazil during the minority of the former emperor's son, Pedro II, soon dissolved into chaos. Paraná formed a political party in 1837 that became known as the Reactionary Party, which evolved into the Party of Order in the early 1840s and in the mid-1850s into the Conservative Party. He and his party's stalwart and unconditional defence of constitutional order allowed the country to move beyond a regency plagued by factious disputes and rebellions that might easily have led to a dictatorship. Appointed president of Rio de Janeiro Province in 1841, Paraná helped put down a rebellion headed by the opposition Liberal Party the following year. Also in 1842, he was elected senator for Minas Gerais and appointed by Pedro II to the Council of State. In 1843, he became the de facto first president (prime minister) of the Council of Ministers, but resigned after a quarrel with the emperor. (Full article...)

Allison Guyot (formerly known as Navoceano Guyot) is a tablemount (guyot) in the underwater Mid-Pacific Mountains of the Pacific Ocean. It is a trapezoidal flat mountain rising 1,500 metres (4,900 ft) above the seafloor to a depth of less than 1,500 metres (4,900 ft), with a summit platform 35 by 70 kilometres (22 by 43 mi) wide. The Mid-Pacific Mountains lie west of Hawaii and northeast of the Marshall Islands, but at the time of their formation were located in the Southern Hemisphere.
The tablemount was probably formed by a hotspot in the present-day Southern Pacific before plate tectonics moved it to its current location. Several hotspots, including the Easter, Marquesas and Society hotspots, may have been involved in the formation of the Mid-Pacific Mountains. Volcanic activity is dated to have occurred circa 111–85 million years ago and formed a volcanic island. Subsequently, carbonate deposition commenced as Allison Guyot subsided and eventually buried the island, forming an atoll-like structure and a carbonate platform. Among other animals, crocodilians lived on Allison Guyot. (Full article...)

The capture of the gendarmerie post in Gornji Lukavac was one of the first actions of the uprising
In June 1941, Serbs in eastern Herzegovina rebelled against the authorities of the Independent State of Croatia (Croatian: Nezavisna Država Hrvatska, NDH), an Axispuppet state established during World War II on the territory of the defeated and occupied Kingdom of Yugoslavia. As the NDH imposed its authority, members of the fascist Ustaše ruling party began a genocidal campaign against Serbs throughout the country. In eastern Herzegovina, the Ustaše perpetrated a series of massacres and attacks against the majority Serb population commencing in the first week of June. Between 3 and 22 June 1941, spontaneous clashes occurred between NDH authorities and groups of Serbs in the region.
The Germaninvasion of the Soviet Union began on 22 June. Over the next two days, the sporadic revolts by Serbs against the NDH in eastern Herzegovina erupted into mass rebellion, triggered by Ustaše persecution, Serb solidarity with the Russian people, hatred and fear of the NDH authorities, and other factors. Serb rebels, under the leadership of both local Serbs and Montenegrins, attacked police, gendarmerie, Ustaše and Croatian Home Guard forces in the region. In the first few days, the rebels captured gendarmerie posts in several villages, set up roadblocks on the major roads and ambushed several military vehicles. On the night of 26 June, the rebels mounted a sustained attack on the town of Nevesinje in an attempt to capture it, but the garrison held out until the morning of 28 June when NDH troops broke through the rebel roadblocks.

The dynasty's history is divided into two periods: during the Northern Song (北宋; 960–1127), the capital was in the northern city of Bianjing (now Kaifeng) and the dynasty controlled most of what is now East China. The Southern Song (南宋; 1127–1279) comprise the period following the loss of control over the northern half of Song territory to the Jurchen-led Jin dynasty in the Jin–Song wars. At that time, the Song court retreated south of the Yangtze and established its capital at Lin'an (now Hangzhou). Although the Song dynasty had lost control of the traditional Chinese heartlands around the Yellow River, the Southern Song Empire contained a large population and productive agricultural land, sustaining a robust economy. In 1234, the Jin dynasty was conquered by the Mongols, who took control of northern China, maintaining uneasy relations with the Southern Song. Möngke Khan, the fourth Great Khan of the Mongol Empire, died in 1259 while besieging the mountain castle Diaoyucheng in Chongqing. His younger brother Kublai Khan was proclaimed the new Great Khan and in 1271 founded the Yuan dynasty. After two decades of sporadic warfare, Kublai Khan's armies conquered the Song dynasty in 1279 after defeating the Southern Song in the Battle of Yamen, and reunited China under the Yuan dynasty.

During the Mesolithic era, the fenland basin was mostly dry and forested, although subject to salt and fresh water incursions. The marshes and meres of this fenland may therefore have been difficult to occupy, other than seasonally, but there is evidence of human settlement on the island since the late Neolithic Age; a Bronze Agecauseway linked the village with the nearby Barway, to the south-east. An investigation, prior to a 1995 development in the village, discovered a farm and large tile-kiln of Romano-British origin; further investigations uncovered an earlier settlement of the Pre-Roman Iron Age. The Roman roadAkeman Street passed through the north-west corner of the parish, and the lost 7th century Anglo-Saxon village of Cratendune may be nearby. (Full article...)
The emperor penguin (Aptenodytes forsteri) is the tallest and heaviest of all living penguin species and is endemic to Antarctica. The male and female are similar in plumage and size, reaching 100 cm (39 in) in length and weighing from 22 to 45 kg (49 to 99 lb). Feathers of the head and back are black and sharply delineated from the white belly, pale-yellow breast and bright-yellow ear patches.
Like all species of penguin, the emperor is flightless, with a streamlined body, and wings stiffened and flattened into flippers for a marine habitat. Its diet consists primarily of fish, but also includes crustaceans, such as krill, and cephalopods, such as squid. While hunting, the species can remain submerged around 20 minutes, diving to a depth of 535 m (1,755 ft). It has several adaptations to facilitate this, including an unusually structured haemoglobin to allow it to function at low oxygen levels, solid bones to reduce barotrauma, and the ability to reduce its metabolism and shut down non-essential organ functions.

Evidence of Stone Age, Bronze Age, and Viking activity has been discovered in Ashton-under-Lyne. The "Ashton" part of the town's name probably dates from the Anglo-Saxon period, and derives from Old English meaning "settlement by ash trees". The origin of the "under-Lyne" suffix is less clear; it possibly derives from the Brittonic-originating word lemo meaning elm or from Ashton's proximity to the Pennines. In the Middle Ages, Ashton-under-Lyne was a parish and township and Ashton Old Hall was held by the de Asshetons, lords of the manor. Granted a royal charter in 1414, the manor spanned a rural area consisting of marshland, moorland, and a number of villages and hamlets. (Full article...)

A hot windstorm brings dust from the surrounding desert, July 3, 1942
Manzanar is the site of one of ten American concentration camps, where more than 120,000 Japanese Americans were incarcerated during World War II from March 1942 to November 1945. Although it had over 10,000 inmates at its peak, it was one of the smaller internment camps. It is located at the foot of the Sierra Nevada mountains in California's Owens Valley, between the towns of Lone Pine to the south and Independence to the north, approximately 230 miles (370 km) north of Los Angeles. Manzanar means "apple orchard" in Spanish. The Manzanar National Historic Site, which preserves and interprets the legacy of Japanese American incarceration in the United States, was identified by the United States National Park Service as the best-preserved of the ten former camp sites.
The first Japanese Americans arrived at Manzanar in March 1942, just one month after President Franklin D. Roosevelt signed Executive Order 9066, to build the camp their families would be staying in. Manzanar was in operation as an internment camp from 1942 until 1945. Since the last of those incarcerated left in 1945, former detainees and others have worked to protect Manzanar and to establish it as a National Historic Site to ensure that the history of the site, along with the stories of those who were incarcerated there, is recorded for current and future generations. The primary focus is the Japanese American incarceration era, as specified in the legislation that created the Manzanar National Historic Site. The site also interprets the former town of Manzanar, the ranch days, the settlement by the Owens Valley Paiute, and the role that water played in shaping the history of the Owens Valley.

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

The last picture ever taken of Johnston, 13 hours before his death at the eruption site
David Alexander Johnston (December 18, 1949 – May 18, 1980) was an American United States Geological Survey (USGS) volcanologist who was killed by the 1980 eruption of Mount St. Helens in the U.S. state of Washington. A principal scientist on the USGS monitoring team, Johnston was killed in the eruption while manning an observation post six miles (10 km) away on the morning of May 18, 1980. He was the first to report the eruption, transmitting "Vancouver! Vancouver! This is it!" before he was swept away by a lateral blast; despite a thorough search, Johnston's body was never found, but state highway workers discovered remnants of his USGS trailer in 1993.
Johnston's career took him across the United States, where he studied the Augustine Volcano in Alaska, the San Juan volcanic field in Colorado, and long-extinct volcanoes in Michigan. Johnston was a meticulous and talented scientist, known for his analyses of volcanic gases and their relationship to eruptions. This, along with his enthusiasm and positive attitude, made him liked and respected by many co-workers. After his death, other scientists lauded his character, both verbally and in dedications and letters. Johnston felt scientists must do what is necessary, including taking risks, to help protect the public from natural disasters. His work, and that of fellow USGS scientists, convinced authorities to close Mount St. Helens to the public before the 1980 eruption. They maintained the closure despite heavy pressure to re-open the area; their work saved thousands of lives. His story became intertwined with the popular image of volcanic eruptions and their threat to society, and a part of volcanology's history. To date, Johnston, along with his mentee Harry Glicken, is one of two American volcanologists known to have died in a volcanic eruption. (Full article...)

Yellow iron oxide-covered lava rock on the flank of Kamaʻehuakanaloa
Kamaʻehuakanaloa Seamount (previously known as Lōʻihi) is an active submarine volcano about 22 mi (35 km) off the southeast coast of the island of Hawaii. The top of the seamount is about 3,200 ft (975 m) below sea level. This seamount is on the flank of Mauna Loa, the largest active subaerialshield volcano on Earth. Kamaʻehuakanaloa is the newest volcano in the Hawaiian–Emperor seamount chain, a string of volcanoes that stretches about 3,900 mi (6,200 km) northwest of Kamaʻehuakanaloa. Unlike most active volcanoes in the Pacific Ocean that make up the active plate margins on the Pacific Ring of Fire, Kamaʻehuakanaloa and the other volcanoes of the Hawaiian–Emperor seamount chain are hotspot volcanoes and formed well away from the nearest plate boundary. Volcanoes in the Hawaiian Islands arise from the Hawaii hotspot, and as the youngest volcano in the chain, Kamaʻehuakanaloa is the only Hawaiian volcano in the deep submarine preshield stage of development.
Kamaʻehuakanaloa began forming around 400,000 years ago and is expected to begin emerging above sea level about 10,000–100,000 years from now. At its summit, Kamaʻehuakanaloa Seamount stands more than 10,000 ft (3,000 m) above the seafloor, making it taller than Mount St. Helens was before its catastrophic 1980 eruption. A diverse microbial community resides around Kamaʻehuakanaloa many hydrothermal vents. (Full article...)
The first volcanic activity at Tuzgle occurred 650,000 years ago and formed the Tuzgle Ignimbrite. Subsequently, lava domes and several lava flows were erupted; scientists have proposed two different schemes of naming the units. The most recent lava flows are dated at 300,000 years ago and volcanic activity may have continued into the Holocene. Several thermal springs are associated with the volcano, and some have been investigated for possible geothermal energy production. Sulfur was formerly mined on the mountain. (Full article...)

Lagoon-facing beach on South Islet
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...)
Africa is the world's second-largest and second-most populous continent after Asia. At about 30.3 million km2 (11.7 million square miles) including adjacent islands, it covers 20% of Earth's land area and 6% of its total surface area. With nearly 1.4 billion people as of 2021, it accounts for about 18% of the world's human population. Africa's population is the youngest among all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Based on 2024 projections, Africa's population will reach 3.8 billion people by 2099. Africa is the least wealthy inhabited continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including geography, climate, corruption, colonialism, the Cold War, and neocolonialism. Despite this low concentration of wealth, recent economic expansion and a large and young population make Africa an important economic market in the broader global context. Africa has a large quantity of natural resources and food resources, including diamonds, sugar, salt, gold, iron, cobalt, uranium, copper, bauxite, silver, petroleum, natural gas, cocoa beans, and.

The Catalan Atlas is a medieval map in the Catalan language, created in 1375. Described as "the zenith of medieval map-work", it is the earliest known chart to use a compass rose. It was produced by the Majorcan cartographic school and is attributed to Abraham Cresques, a Jewish book illuminator described by a contemporary as a master of mappae mundi. It has been in the royal library of France (now the Bibliothèque nationale de France) since the time of King Charles V. The atlas originally consisted of six vellum leaves, each about 64.5 by 50 cm (25.4 by 19.7 in), folded vertically and painted in various colours including gold and silver. This picture is a montage of eight pages (four leaves) of the atlas, depicting Europe, northern Africa and Asia.

Fanny Bullock Workman (1859–1925) was an American geographer, cartographer, explorer, travel writer, and mountaineer. Together with her husband, William Hunter Workman, she traveled by bicycle through Switzerland, France, Italy, Spain, Algeria and India; after taking up climbing in the Himalayas, she set a women's altitude record on Pinnacle Peak, reaching 23,000 feet (7,000 m). She published eight travel books, with particular focus on the lives of women in the countries she visited, and championed women's rights and women's suffrage.
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.

A map of the United States showing its 50 states, federal district and five inhabited territories. Alaska, Hawaii, and the territories are shown at different scales, and the Aleutian Islands and the uninhabited northwestern Hawaiian Islands are omitted from the map. The United States of America is a federal republic consisting of 50 states, a federal district (Washington, D.C., the capital city of the United States), five major territories, and various minor islands. Both the states and the United States as a whole are each sovereign jurisdictions. The Tenth Amendment to the United States Constitution allows states to exercise all powers of government not delegated to the federal government. Each state has its own constitution and government, and all states and their residents are represented in the federal Congress, a bicameral legislature consisting of the Senate and the House of Representatives. Each state elects two senators, while representatives are distributed among the states in proportion to the most recent constitutionally mandated decennial census. Additionally, each state is entitled to select a number of electors to vote in the Electoral College, the body that elects the president of the United States, equal to the total of representatives and senators in Congress from that state. The federal district does not have representatives in the Senate, but has a non-voting delegate in the House, and it is also entitled to electors in the Electoral College. Congress can admit more states, but it cannot create a new state from territory of an existing state or merge two or more states into one without the consent of all states involved, and each new state is admitted on an equal footing with the existing states.
