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 Riegelmann Boardwalk (also known as the Coney Island Boardwalk) is a 2.7-mile-long (4.3 km) boardwalk on the southern shore of the Coney Island peninsula in Brooklyn, New York City, United States. Opened in 1923, the boardwalk runs along the Atlantic Ocean between West 37th Street to the west, at the edge of the Sea Gate neighborhood, and Brighton 15th Street to the east, in Brighton Beach. It is operated by the New York City Department of Parks and Recreation (NYC Parks).
The Riegelmann Boardwalk is primarily made of wooden planks arranged in a chevron pattern. It ranges from 50 to 80 feet (15 to 24 m) wide and is raised slightly above sea level. The boardwalk connects several amusement areas and attractions on Coney Island, including the New York Aquarium, Luna Park, Deno's Wonder Wheel Amusement Park, and Maimonides Park. It has become an icon of Coney Island, with numerous appearances in the visual arts, music, and film. After its completion, the boardwalk was considered the most important public works project in Brooklyn since the Brooklyn Bridge, with a comparable impact to the Catskill Watershed and Central Park.

The Empire of Brazil was a 19th-century state that broadly comprised the territories which form modern Brazil and Uruguay until the latter achieved independence in 1828. The empire's government was a representative parliamentary constitutional monarchy under the rule of Emperors Pedro I and his son Pedro II. A colony of the Kingdom of Portugal, Brazil became the seat of the Portuguese Empire in 1808, when the Portuguese Prince regent, later King Dom John VI, fled from Napoleon's invasion of Portugal and established himself and his government in the Brazilian city of Rio de Janeiro. John VI later returned to Portugal, leaving his eldest son and heir-apparent, Pedro, to rule the Kingdom of Brazil as regent. On 7 September 1822, Pedro declared the independence of Brazil and, after waging a successful war against his father's kingdom, was acclaimed on 12 October as Pedro I, the first Emperor of Brazil. The new country was huge, sparsely populated, and ethnically diverse.
Unlike most of the neighboring Hispanic American republics, Brazil had political stability, vibrant economic growth, constitutionally guaranteed freedom of speech, and respect for civil rights of its subjects, albeit with legal restrictions on women and slaves, the latter regarded as property and not citizens. The Empire's bicameral parliament was elected under comparatively democratic methods for the era, as were the provincial and local legislatures. This led to a long ideological conflict between Pedro I and a sizable parliamentary faction over the role of the monarch in the government. He also had to face other obstacles. The unsuccessful Cisplatine War against the neighboring United Provinces of the Río de la Plata in 1828 led to the secession of the province of Cisplatina (later to become Uruguay). In 1826, despite his role in Brazilian independence, he became the king of Portugal; he abdicated the Portuguese throne in favor of his eldest daughter. Two years later, she was usurped by Pedro I's younger brother Miguel. Unable to deal with both Brazilian and Portuguese affairs, Pedro I abdicated his Brazilian throne on 7 April 1831 and immediately departed for Europe to restore his daughter to the Portuguese throne.

SMS Weissenburg was one of the first ocean-going battleships of the Imperial German Navy. She was the third pre-dreadnought of the Brandenburg class, which also included her sister ships Brandenburg, Wörth, and Kurfürst Friedrich Wilhelm. Weissenburg was laid down in 1890 in the AG Vulcan dockyard in Stettin, launched in 1891, and completed in 1894. The Brandenburg-class battleships were unique for their era in that they carried six large-caliber guns in three twin turrets, as opposed to four guns in two turrets, as was the standard in other navies.
Weissenburg served with I Division during the first decade of her service with the fleet. This period was generally limited to training exercises and goodwill visits to foreign ports. These training maneuvers were nevertheless very important to developing German naval tactical doctrine in the two decades before World War I, especially under the direction of Alfred von Tirpitz. Weissenburg, along with her three sisters, saw only one major overseas deployment during this period, to China in 1900–1901, during the Boxer Uprising. The ship underwent a major modernization in 1904–1905. (Full article...)
Keswick (/ˈkɛzɪk/ KEZ-ik) is a market town and civil parish in the Cumberland unitary authority area of Cumbria, England. Historically, until 1974, it was part of the county of Cumberland. It lies within the Lake District National Park, just north of Derwentwater and four miles (six kilometres) from Bassenthwaite Lake. The parish had a population of 5,243 at the 2011 census.
There is evidence of prehistoric occupation of the area, but the first recorded mention of the town dates from the 13th century, when Edward I of England granted a charter for Keswick's market, which has maintained a continuous 700-year existence. The town was an important mining area, and from the 18th century has been known as a holiday centre; tourism has been its principal industry for more than 150 years. Its features include the Moot Hall; a modern theatre, the Theatre by the Lake; one of Britain's oldest surviving cinemas, the Alhambra; and the Keswick Museum and Art Gallery in the town's largest open space, Fitz Park. Among the town's annual events is the Keswick Convention, an Evangelical gathering attracting visitors from many countries. (Full article...)

Ireland is an island in Northern Europe in the north Atlantic Ocean. The island, of up to around 480 km (300 mi) north-south, and 275 km (171 mi) east-west, lies near the western edge of the European continental shelf, part of the Eurasian Plate. Its main geographical features include low central plains surrounded by coastal mountains. The highest peak is Carrauntoohil (Irish: Corrán Tuathail), which is 1,039 metres (3,409 ft) above sea level. The western coastline is rugged, with many islands, peninsulas, headlands and bays, while the southern and northern coasts feature a smaller number of substantial sea inlets, such as Lough Foyle and Cork Harbour; no part of the land is more than around 110 km (68 mi) from the sea. It was administratively divided into 32 counties, gathered in 4 provinces, though current arrangements, especially in Northern Ireland, differ from this model. The island is almost bisected by the River Shannon, which at 360.5 km (224 mi) with a 102.1 km (63 mi) estuary is the longest river in Ireland and flows south from County Cavan in the province of Ulster to form the boundary between Connacht and Leinster, and later Munster, and meet the Atlantic just south and west of Limerick. There are a number of sizeable lakes along Ireland's rivers, of which Lough Neagh is the largest.
Politically, the island consists of the Republic of Ireland, with jurisdiction over about five-sixths of the island, and Northern Ireland, a constituent part of the United Kingdom, with jurisdiction over the remaining sixth. Located west of the island of Great Britain, Ireland lies at approximately . It has a total area of 84,421 km (32,595 sq mi) and is separated from Great Britain by the Irish Sea, bounded to the north and south respectively by the North Channel and St George's Channel, and from mainland Europe by the Celtic Sea. Ireland forms the second largest landmass in the British Isles, together with Great Britain and the Isle of Man. (Full article...)
Nevado del Ruiz (Spanish pronunciation: [neβaðo ðel ˈrwis]), also known as La Mesa de Herveo (English: Mesa of Herveo, the name of the nearby town) is a volcano on the border of the departments of Caldas and Tolima in Colombia, being the highest point of both. It is located about 130 km (81 mi) west of the capital city Bogotá. It is a stratovolcano composed of many layers of lava alternating with hardened volcanic ash and other pyroclastic rocks. Volcanic activity at Nevado del Ruiz began about two million years ago, during the Early Pleistocene or Late Pliocene, with three major eruptive periods. The current volcanic cone formed during the present eruptive period, which began 150,000 years ago.
The volcano usually generates Vulcanian to Plinian eruptions, which produce swift-moving currents of hot gas and rock called pyroclastic flows. These eruptions often cause massive lahars (mud and debris flows), which pose a threat to human life and the environment. The impact of such an eruption is increased as the hot gas and lava melt the mountain's snowcap, adding large quantities of water to the flow. On November 13, 1985, a small eruption produced an enormous lahar that buried and destroyed the town of Armero in Tolima, causing an estimated 25,000 deaths. This event later became known as the Armero tragedy—the deadliest lahar in recorded history. Similar but less deadly incidents occurred in 1595 and 1845, consisting of a small explosive eruption followed by a large lahar. (Full article...)
Dona Maria 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 Dom Pedro 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.

T3 was a sea-going torpedo boat that was operated by the Royal Yugoslav Navy between 1921 and 1941. Originally 78 T, a 250t-class torpedo boat of the Austro-Hungarian Navy built in 1914, she was armed with two 66 mm (2.6 in) guns, four 450 mm (17.7 in) torpedo tubes, and could carry 10–12 naval mines. She saw active service during World War I, performing convoy, escort and minesweeping tasks, anti-submarine operations and shore bombardment missions. In 1917 the suffixes of all Austro-Hungarian torpedo boats were removed, and thereafter she was referred to as 78. She was part of the escort force for the Austro-Hungarian dreadnought Szent István during the action that resulted in the sinking of that ship by Italian torpedo boats in June 1918.
Following Austria-Hungary's defeat in 1918, she was allocated to the Navy of the Kingdom of Serbs, Croats and Slovenes, which later became the Royal Yugoslav Navy, and was renamed T3. At the time, she and the seven other 250t-class boats were the only modern sea-going vessels of the fledgling maritime force. During the interwar period, T3 and the rest of the navy were involved in training exercises and cruises to friendly ports, but activity was limited by reduced naval budgets. The ship was captured by the Italians during the Axis invasion of Yugoslavia in April 1941. After her main armament was modernised and her crew increased to 62, she served with the Royal Italian Navy under her Yugoslav designation, although she was only used for coastal and second-line tasks. Following the Italian capitulation in September 1943, she was captured by Germany and, after being fitted with additional anti-aircraft guns, served with the German Navy or the Navy of the Independent State of Croatia as TA48. In German/Croatian service her crew of 52 consisted entirely of Croatian officers and enlisted men. She was sunk by Allied aircraft in February 1945 while in the port of Trieste, where she had been built. (Full article...)
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...)
Tryon Creek is a 4.85-mile (7.81 km) tributary of the Willamette River in the U.S. state of Oregon. Part of the drainage basin of the Columbia River, its watershed covers about 6.5 square miles (16.8 km) in Multnomah and Clackamas counties. The stream flows southeast from the Tualatin Mountains (West Hills) through the Multnomah Village neighborhood of Portland and the Tryon Creek State Natural Area to the Willamette in the city of Lake Oswego. Parks and open spaces cover about 21 percent of the watershed, while single-family homes dominate most of the remainder. The largest of the parks is the state natural area, which straddles the border between the two cities and counties.
The bedrock under the watershed includes part of the last exotic terrane, a chain of seamounts, acquired by the North American Plate as it moved west during the Eocene. Known as the Waverly Hills Formation, it lies buried under ash and lava from later volcanic eruptions, sediments from flooding and erosion, and layers of wind-blown silt. Two dormant volcanoes from the Boring Lava Field are in the Tryon Creek watershed. (Full article...)
