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...)

![Image 1 Volubilis ruins Volubilis (Latin pronunciation: [wɔˈɫuːbɪlɪs]; Arabic: وليلي, romanized: walīlī; Berber languages: ⵡⵍⵉⵍⵉ, romanized: wlili) is a partly-excavated Berber-Roman city in Morocco situated near the city of Meknes that may have been the capital of the Kingdom of Mauretania, at least from the time of King Juba II. Before Volubilis, the capital of the kingdom may have been at Gilda. Built in a fertile agricultural area, it developed from the 3rd century BC onward as a Berber, then proto-Carthaginian, settlement before being the capital of the kingdom of Mauretania. It grew rapidly under Roman rule from the 1st century AD onward and expanded to cover about 42 hectares (100 acres) with a 2.6 km (1.6 mi) circuit of walls. The city gained a number of major public buildings in the 2nd century, including a basilica, temple and triumphal arch. Its prosperity, which was derived principally from olive growing, prompted the construction of many fine town-houses with large mosaic floors.

![Image 2 The sky at Cherry Springs State Park, the second International Dark Sky Park and the first in the eastern US, is so dark that the Milky Way casts a visible shadow. Cherry Springs State Park is an 82-acre (33 ha)[a] Pennsylvania state park in Potter County, Pennsylvania, United States. The park was created from land within the Susquehannock State Forest, and is on Pennsylvania Route 44 in West Branch Township. Cherry Springs, named for a large stand of Black Cherry trees in the park, is atop the dissected Allegheny Plateau at an elevation of 2,300 feet (701 m). It is popular with astronomers and stargazers for having "some of the darkest night skies on the east coast" of the United States, and was chosen by the Pennsylvania Department of Conservation and Natural Resources (DCNR) and its Bureau of Parks as one of "25 Must-See Pennsylvania State Parks". The earliest recorded inhabitants of the area were the Susquehannocks, followed by the Seneca nation, who hunted there. The first settlement within the park was a log tavern built in 1818 along a trail; the trail became a turnpike by 1834 and a hotel replaced the tavern in 1874, then burned in 1897. In the late 19th and early 20th centuries the old-growth forests were clearcut; the state forest was established in 1901 and contains second growth woodlands. "Cherry Springs Scenic Drive" was established in 1922, and the Civilian Conservation Corps built much of Cherry Springs State Park during the Great Depression, including a picnic pavilion listed on the National Register of Historic Places (NRHP). An annual "Woodsmen's Show" has been held in the park each August since 1952. (Full article...)](/key/File:Blank.png)

The orca (Orcinus orca), or killer whale, is a toothed whale that is the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus. Orcas are recognizable by their black-and-white patterned body. A cosmopolitan species, they are found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.
Orcas are apex predators with a diverse diet. Individual populations often specialize in particular types of prey. This includes a variety of fish, sharks, rays, and marine mammals such as seals and other dolphins and whales. They are highly social; some populations are composed of highly stable matrilineal family groups (pods). Their sophisticated hunting techniques and vocal behaviors, often specific to a particular group and passed along from generation to generation, are considered to be manifestations of animal culture.

Little Thetford /ˈθɛtfɔːrd/ is a small village in the civil parish of Thetford, 3 miles (5 km) south of Ely in Cambridgeshire, England, about 76 miles (122 km) by road from London. The village is built on a boulder clay island surrounded by flat fenland countryside, typical of settlements in this part of the East of England.
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 Age causeway 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 road Akeman 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...)
Kigali (Kinyarwanda pronunciation: [ci.ɡɑ́.ɾi]) is the capital and largest city of Rwanda. It is near the nation's geographic centre in a region of rolling hills, with a series of valleys and ridges joined by steep slopes. As a primate city, Kigali is a relatively new city. It has been Rwanda's economic, cultural, and transport hub since it was founded as an administrative outpost in 1907, and became the capital of the country at independence in 1962, shifting focus away from Huye.
In an area controlled by the Kingdom of Rwanda from the 15th century, and then, by the German Empire in the beginning of the 20th century, the city was founded in 1907 when Richard Kandt, the colonial resident, chose the site for his headquarters, citing its central location, views and security. Foreign merchants began to trade in the city during the German era, and Kandt opened some government-run schools for Tutsi Rwandan students. Belgium took control of Rwanda and Burundi during World War I, forming the mandate of Ruanda-Urundi. Kigali remained the seat of colonial administration for Rwanda but Ruanda-Urundi's capital was at Usumbura (now Bujumbura) in Burundi and Kigali remained a small city with a population of just 6,000 at the time of independence.

Dom Pedro II (2 December 1825 – 5 December 1891), nicknamed the Magnanimous (Portuguese: O Magnânimo), was the second and last monarch of the Empire of Brazil, reigning for over 58 years.
Pedro II was born in Rio de Janeiro, the seventh child of Emperor Dom Pedro I of Brazil and Empress Dona Maria Leopoldina and thus a member of the Brazilian branch of the House of Braganza (Portuguese: Bragança). His father's abrupt abdication and departure to Europe in 1831 left the five-year-old as emperor and led to a lonely childhood and adolescence, obliged to spend his time studying in preparation for rule. His experiences with court intrigues and political disputes during this period greatly affected his later character; he grew into a man with a strong sense of duty and devotion toward his country and his people, yet increasingly resentful of his role as monarch.

Alodia, also known as Alwa (Greek: Αρουα, Aroua; Arabic: علوة, ʿAlwa), was a medieval kingdom in what is now central and southern Sudan. Its capital was the city of Soba, located near modern-day Khartoum at the confluence of the Blue and White Nile rivers.
Founded sometime after the ancient Kingdom of Kush fell, around 350 AD, Alodia is first mentioned in historical records in 569. It was the last of the three Nubian kingdoms to convert to Christianity in 580, following Nobadia and Makuria. It possibly reached its peak during the 9th–12th centuries when records show that it exceeded its northern neighbor, Makuria, with which it maintained close dynastic ties, in size, military power and economic prosperity. Alodia was a large, multicultural state administered by a powerful king and provincial governors appointed by him. The capital Soba, described as a town of "extensive dwellings and churches full of gold and gardens", prospered as a trading hub. Goods arrived from Makuria, the Middle East, western Africa, India and even China. Literacy in both Nubian and Greek flourished. (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...)
George Town is the capital of the Malaysian state of Penang. It is the core city of the George Town Conurbation, Malaysia's second largest metropolitan area with a population of 2.84 million and the second highest contributor to the country's GDP. The city proper spans an area of 306 km (118 sq mi) encompassing Penang Island and surrounding islets, and had a population of 794,313 as of 2020.
Initially established as an entrepôt by Francis Light in 1786, George Town serves as the commercial centre for northern Malaysia. According to Euromonitor International and the Economist Intelligence Unit, it has the highest potential for revenue growth among all Malaysian cities and contributed nearly 8 per cent of the country's personal disposable income in 2015, second only to the national capital, Kuala Lumpur. Its technological sector, anchored by hundreds of multinational companies, has made George Town the top exporter in the country. The Penang International Airport links George Town to several regional cities, while a ferry service and two road bridges connect the city to the rest of Peninsular Malaysia. Swettenham Pier is the busiest cruise terminal in the country. (Full article...)
Triton is the largest natural satellite of the planet Neptune. It is the only moon of Neptune massive enough to be rounded under its own gravity and hosts a thin but well-structured atmosphere. Triton orbits Neptune in a retrograde orbit— revolving in the opposite direction to the parent planet's rotation — the only large moon in the Solar System to do so. Triton is thought to have once been a dwarf planet from the Kuiper belt, captured into Neptune's orbit by the latter's gravity.
At 2,710 kilometers (1,680 mi) in diameter, Triton is the seventh-largest moon in the Solar System, the second-largest planetary moon in relation to its primary (after Earth's Moon), and larger than all of the known dwarf planets. The mean density is 2.061 g/cm, reflecting a composition of approximately 30–45% water ice by mass, with the rest being mostly rock and metal. Triton is differentiated, with a crust of primarily ice atop a probable subsurface ocean of liquid water and a solid rocky-metallic core at its center. Although Triton's orbit is nearly circular with a very low orbital eccentricity of 0.000016, Triton's interior may still experience tidal heating through obliquity tides. (Full article...)
