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...)

The Three Sisters, looking north
The Three Sisters are closely spaced volcanic peaks in the U.S. state of Oregon. They are part of the Cascade Volcanic Arc, a segment of the Cascade Range in western North America extending from southern British Columbia through Washington and Oregon to Northern California. Each over 10,000 feet (3,000 meters) in elevation, they are the third-, fourth- and fifth-highest peaks in Oregon. Located in the Three Sisters Wilderness at the boundary of Lane and Deschutes counties and the Willamette and Deschutes national forests, they are about 10 miles (16 kilometers) south of the nearest town, Sisters. Diverse species of flora and fauna inhabit the area, which is subject to frequent snowfall, occasional rain, and extreme temperature variation between seasons. The mountains, particularly South Sister, are popular destinations for climbing and scrambling.
Although they are often grouped together as one unit, the three mountains have their own individual geology and eruptive history. Neither North Sister nor Middle Sister has erupted in the last 14,000 years, and it is considered unlikely that either will ever erupt again. South Sister last erupted about 2,000 years ago and could erupt in the future, threatening life within the region. After satellite imagery detected tectonic uplift near South Sister in 2000, the United States Geological Survey improved monitoring in the immediate area. (Full article...)

Looking south across the reserve, with reed beds in the foreground
The Ham Wall reserve was constructed originally to provide reed bed habitat for the Eurasian bittern, which at the time was at a very low population level in the UK. The site is divided into several sections with independently controllable water levels, and machinery and cattle are used to maintain the quality of the reed beds. There are important breeding populations of wetland birds including the rare little bittern and great white egret, and the area hosts several other uncommon animals and plants. The RSPB works with other organisations as part of the Avalon Marshes Partnership to coordinate conservation issues across the Somerset Levels. (Full article...)
Combe Hill is a causewayed enclosure, near Eastbourne in East Sussex, on the northern edge of the South Downs. It consists of an inner circuit of ditches and banks, incomplete where it meets a steep slope on its north side, and the remains of an outer circuit. Causewayed enclosures were built in England from shortly before 3700 BC until at least 3500 BC; they are characterized by the full or partial enclosure of an area with ditches that are interrupted by gaps, or causeways. Their purpose is not known; they may have been settlements, meeting places, or ritual sites. The historian Hadrian Allcroft included the site in his 1908 book Earthwork of England, and in 1930 E. Cecil Curwen listed it as a possible Neolithic site in a paper which attempted to provide the first list of all the causewayed enclosures in England.
The enclosure has been excavated twice: in 1949, by Reginald Musson, and in 1962, by Veronica Seton-Williams, who used it as a training opportunity for volunteers. Charcoal fragments from Musson's dig were later dated to between 3500 and 3300 BC. Musson also found a large quantity of Ebbsfleet ware pottery in one of the ditches. Seton-Williams found three polished stone axes deposited in another ditch, perhaps not long after it had been dug. The site is only 800 m (870 yd) from Butts Brow, another Neolithic enclosure, and the two locations are visible from each other; both sites may have seen Neolithic activity at the same time.

The region was first settled by Paleo-IndianNative Americans; by the time European American explorers arrived, it was inhabited by Skagit tribes. By the early 19th century, the region was visited by fur trappers and several British and American companies vied for control over the fur trade. After the Canada–United States border was set at the 49th parallel in 1846, explorers came to chart potential routes through the mountains for roads and railroads. Limited mining and logging occurred from the late 19th century to the early 20th century. The first significant human impact in the region occurred in the 1920s when several dams were built in the Skagit River valley to generate hydroelectric power. Environmentalists then campaigned to preserve the remaining wilderness, culminating on October 2, 1968, with the designation of North Cascades National Park. (Full article...)
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...)
The history of Lithuania between 1219 and 1295 concerns the establishment and early history of the first Lithuanian state, the Grand Duchy of Lithuania. The beginning of the 13th century marks the end of the prehistory of Lithuania. From this point on the history of Lithuania is recorded in chronicles, treaties, and other written documents. In 1219, 21 Lithuanian dukes signed a peace treaty with Galicia–Volhynia. This event is widely accepted as the first proof that the Baltic tribes were uniting and consolidating. Despite continuous warfare with two Christian orders, the Livonian Order and the Teutonic Knights, the Grand Duchy of Lithuania was established and gained some control over the lands of Black Ruthenia, Polatsk, Minsk, and other territories east of modern-day Lithuania that had become weak and vulnerable after the collapse of Kievan Rus'.
The first ruler to hold the title of Grand Duke was Mindaugas. Traditionally he is considered the founder of the state, the one who united the Baltic tribes and established the Duchy. Some scholars, however, challenge this perception, arguing that an organized state existed before Mindaugas, possibly as early as 1183. After quelling an internal war with his nephews, Mindaugas was baptized in 1251, and was crowned as King of Lithuania in 1253. In 1261, he broke the peace with the Livonian Order, perhaps even renouncing Christianity. His assassination in 1263 by Treniota ended the early Christian kingdom in Lithuania. For another 120 years Lithuania would remain a pagan empire, fighting against the Teutonic and Livonian Orders during the Northern Crusades during their attempts to Christianize the land.

The fungus grows in coniferous forests in its native range, and pine plantations in countries where it has become naturalised. It forms symbioticectomycorrhizal associations with living trees by enveloping the tree's underground roots with sheaths of fungal tissue, and is sometimes parasitised by the related mushroom Gomphidius roseus. Suillus bovinus produces spore-bearing fruit bodies, often in large numbers, above ground. The mushroom has a convex grey-yellow or ochre cap reaching up to 10 cm (4 in) in diameter, which flattens with age. Like other boletes, it has tubes extending downward from the underside of the cap, rather than gills; spores escape at maturity through the tube openings, or pores. The pore surface is yellow. The stipe, more slender than those of other Suillus boletes, lacks a ring. (Full article...)
DonaMaria Amélia (1 December 1831 – 4 February 1853) was a princess of the Empire of Brazil and a member of the Brazilian branch of the House of Braganza. Her parents were Emperor DomPedro I, the first ruler of Brazil, and Amélie of Leuchtenberg. The only child of her father's second marriage, Maria Amélia was born in France after Pedro I abdicated the Brazilian throne in favor of his son Dom Pedro II. Before Maria Amélia was a month old, Pedro I went to Portugal to restore the crown of the eldest daughter of his first marriage, Dona Maria II. He fought a successful war against his brother Miguel I, who had usurped Maria II's throne.
Only a few months after his victory, Pedro I died from tuberculosis. Maria Amélia's mother took her to Portugal, where she remained for most of her life without ever visiting Brazil. The Brazilian government refused to recognize Maria Amélia as a member of Brazil's Imperial House because she was foreign-born, but when her elder half-brother Pedro II was declared of age in 1840, he successfully intervened on her behalf.

Powder House Island (also known as Dynamite Island) is an artificial island on the lower Detroit River in southeast Michigan, directly adjacent to the Canada–United States border. It was constructed in the late 1880s by the Dunbar & Sullivan Company to store explosives during their dredging of the Livingstone Channel. It was constructed in a successful attempt to circumvent an 1880 court order forbidding the company to store explosives on nearby Fox Island.
Powder House Island was the location of dynamite storage sheds, as well as a dynamite factory and several ice houses. During this time, it was the site of a series of accidents, including fires in 1895 and 1919 (which both burned the island "to the water's edge"). Twenty short tons (18,000 kg) of the island's dynamite exploded in 1906 after two men "had been shooting with a revolver" near it; while there were no deaths (and only minor injuries to the two men), windows were shattered 3 mi (4.8 km) away and the explosion was clearly audible from 85 mi (137 km) away.

A view of Neilston from the southwest, with the city of Glasgow in the distance
Neilston is mentioned in documents from the 12th century, when the feudal lord Robert de Croc, endowed a chapel to Paisley Abbey to the North. Neilston Parish Church—a Category B listed building—is said to be on the site of this original chapel and has been at the centre of the community since 1163. Little remains of the original structure. Before industrialisation, Neilston was a scattered farming settlement composed of a series of single-storey houses, many of them thatched. Some domestic weaving was carried out using local flax. Water power from nearby streams ground corn and provided a suitable environment for bleaching the flax. (Full article...)

Io, with two plumes erupting from its surface Volcanism on Io, a moon of Jupiter, is represented by the presence of volcanoes, volcanic pits and lava flows on the surface. Io's volcanic activity was discovered in 1979 by Linda Morabito, an imaging scientist working on Voyager 1. Observations of Io by passing spacecraft and Earth-based astronomers have revealed more than 150 active volcanoes. , up to 400 such volcanoes are predicted to exist based on these observations.[outdated statistic] Io's volcanism makes the satellite one of only four known currently volcanically or cryovolcanically active worlds in the Solar System (the others being Earth, Saturn's moon Enceladus, and Neptune's moon Triton.)
First predicted shortly before the Voyager 1 flyby, the heat source for Io's volcanism comes from tidal heating produced by its forced orbital eccentricity. This differs from Earth's internal heating, which is derived primarily from radioactive isotope decay and primordial heat of accretion. Io's eccentric orbit leads to a slight difference in Jupiter's gravitational pull on the satellite between its closest and farthest points on its orbit, causing a varying tidal bulge. This variation in the shape of Io causes frictional heating in its interior. Without this tidal heating, Io might have been similar to the Moon, a world of similar size and mass, geologically dead and covered with numerous impact craters. (Full article...)

The frontispiece of the 1920 edition of Tod's Annals and Antiquities of Rajast'han
Lieutenant-Colonel James Tod (20 March 1782 – 18 November 1835) was an officer of the British East India Company and an Oriental scholar. He combined his official role and his amateur interests to create a series of works about the history and geography of India, and in particular the area then known as Rajputana that corresponds to the present day state of Rajasthan, and which Tod referred to as Rajast'han.
Tod was born in London and educated in Scotland. He joined the East India Company as a military officer and travelled to India in 1799 as a cadet in the Bengal Army. He rose quickly in rank, eventually becoming captain of an escort for an envoy in a Sindian royal court. After the Third Anglo-Maratha War, during which Tod was involved in the intelligence department, he was appointed Political Agent for some areas of Rajputana. His task was to help unify the region under the control of the East India Company. During this period Tod conducted most of the research that he would later publish. Tod was initially successful in his official role, but his methods were questioned by other members of the East India Company. Over time, his work was restricted and his areas of oversight were significantly curtailed. In 1823, owing to declining health and reputation, Tod resigned his post as Political Agent and returned to England. (Full article...)

Joppenbergh Mountain, viewed from across the Rondout Creek
Joppenbergh Mountain is a nearly 500-foot (152 m) mountain in Rosendale Village, a hamlet in the town of Rosendale, in Ulster County, New York. The mountain is composed of a carbonatebedrock overlain by glacially deposited material. It was named after Rosendale's founder, Jacob Rutsen, and mined throughout the late 19th century for dolomite that was used in the manufacture of natural cement. Extensive mining caused a large cave-in on December 19, 1899, that destroyed equipment and collapsed shafts within Joppenbergh. Though it was feared that several workers had been killed, the collapse happened while all the miners were outside, eating lunch. Since the collapse, the mountain has experienced shaking and periodic rockfalls.
During the late 1930s, Joppenbergh became the site of several ski jumping competitions, which continued until the early 1940s. The original slope was designed by Harold Schelderup for Rosendale's first competition in 1937; Schelderup himself skied that July, after the slope was coated with borax for a summer competition. Several Olympic skiers participated in the competitions. Skiing began again in the 1960s, when a new slope was built on the mountain, and the revived competitions continued until 1971.

The size of Africa compared to the other continentsAfrica 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 1.4 billion people0 as of 2021, it accounts for about 18% of the world's human population. Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4. Despite a wide range of natural resources, Africa is the least wealthy continent per capita and second-least wealthy by total wealth, ahead of Oceania. Scholars have attributed this to different factors including geography, climate, tribalism, colonialism, the Cold War, neocolonialism, lack of democracy, and corruption. Despite this low concentration of wealth, recent economic expansion and the large and young population make Africa an important economic market in the broader global context. (Full article...)

The Mitchell Map is the most comprehensive map of eastern North America made during the colonial era. Measuring about 6.5 ft (2.0 m) wide by 4.5 ft (1.4 m) high, it was produced by John Mitchell in 1757 in eight separate sheets. The map was used during the Treaty of Paris for defining the boundaries of the United States, and remains important today for resolving border disputes.
This picture is a panoramic map of North Cascades National Park, as viewed from the east, created in 1987 by Austrian painter and cartographer Heinrich C. Berann for the National Park Service.
The Kavrayskiy VII projection is a map projection invented by Vladimir V. Kavrayskiy in 1939 as a general purpose pseudocylindrical projection. It produces maps with low overall distortion, despite its straight, evenly-spaced parallels and a simple formulation.
The van der Grinten projection is a compromise map projection that is neither equal-area nor conformal. It projects the entire Earth into a circle, though the polar regions are subject to extreme distortion. The projection was the first of four proposed by Alphons J. van der Grinten in 1904, and, unlike perspective projections, is an arbitrary geometric construction on the plane. It was adopted as the National Geographic Society's reference map of the world from 1922 until 1988.
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.

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.
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.
A detailed eighteenth-century map of Scandinavia by J. B. Homann, depicting Denmark, Norway, Sweden, Finland and the Baltic states of Livonia, Latvia and Curlandia. The map notes fortified cities, villages, roads, bridges, forests, castles and topography. The elaborate title cartouche in the upper left quadrant features angels supporting a title curtain and a medallion supporting an alternative title in French, "Les Trois Covronnes du Nord".
Born in 1664, Homann became an engraver and cartographer in the late 17th century, and opened his own publishing house in 1702. In 1715 Emperor Charles VI appointed him Imperial Geographer of the Holy Roman Empire. Homann held the position until his death in 1724.
Daedongyeojido is a large scale map of Korea produced by Chosun Dynasty cartographer and geologist Kim Jeong-ho in 1861. Considered to mark the zenith of pre-modern Korean cartography, the map consists of 22 separate, foldable booklets, each covering approximately 47 kilometres (29 mi) (north-south) by 31.5 kilometres (19.6 mi) (east-west). Combined, they form a map of Korea that is 6.7 metres (22 ft) wide and 3.8 metres (12 ft) long. Daedongyeojido is praised for precise delineations of mountain ridges, waterways, and transportation routes, as well as its markings for settlements, administrative areas, and cultural sites.
Although born in Britain, his early career was in the United States, where at a young age, he held senior positions in the developing tramway systems of Detroit and New Jersey. In 1898, he served in the United States Navy during the short Spanish–American War. (Full article...)
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 uninhabitednorthwestern Hawaiian Islands are omitted from this 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 is represented by 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.

Map: Strebe, using GeocartThe Hammer retroazimuthal projection is a modified azimuthal proposed by Ernst Hermann Heinrich Hammer in 1910. As a retroazimuthal projection, azimuths (directions) are correct from any point to the designated center point. In whole-world presentation, the back and front hemispheres overlap, making the projection a surjective function. Here, the frontside and backside hemispheres, both with a 15° graticule and center point of 45°N, 90°W, are presented side-by-side.

At more than 500,000 acres (200,000 ha), North Cascades National Park is the largest of the three National Park Service units that comprise the North Cascades National Park Complex. North Cascades National Park consists of a northern and southern section, bisected by the Skagit River that flows through Ross Lake National Recreation Area. Lake Chelan National Recreation Area lies on the southern border of the south unit of the park. In addition to the two national recreation areas, other protected lands including several national forests and wilderness areas, as well as Canadian provincial parks in British Columbia, nearly surround the park. North Cascades National Park features the rugged mountain peaks of the North Cascades Range, the most expansive glacial system in the contiguous United States, the headwaters of numerous waterways, and vast forests with the highest degree of flora biodiversity of any American national park.
