Santiago Island (Galápagos)
Santiago Island is one of the Galápagos Islands. The island, which consists of two overlapping volcanoes, has an area of and a maximum altitude of , atop the northwestern shield volcano. The volcano in the island's southeast erupted along a linear fissure and is much lower. The oldest lava flows on the island date back to 750,000 years ago. Names The original Spanish name was San Marcos Island ( or ), honoring Saint Mark the Evangelist. In 1892, as part of Ecuador's celebration of the quadricentennial of Columbus's first voyage, it was renamed Salvador or San Salvador Island () after the first island Columbus reached. Isabela and Fernandina were similarly renamed for the third and fourth islands. The present name ''Santiago'' () is the Spanish name of Saint James and a major center of pilgrimage in northern Spain. In English, the island has also been known as Duke of York's Island, King James's Island, and James Island, all in honor of King JamesII of England a ...

Galápagos Islands
The Galápagos Islands () are an archipelago of volcanic islands in the Eastern Pacific, located around the equator, west of the mainland of South America. They form the Galápagos Province of the Republic of Ecuador, with a population of slightly over 33,000 (2020). The province is divided into the Cantons of Ecuador, cantons of San Cristóbal Island, San Cristóbal, Santa Cruz Island (Galápagos), Santa Cruz, and Isabela Island (Galápagos), Isabela, the three most populated islands in the chain. The Galápagos are famous for their large number of Endemism, endemic species, which were studied by Charles Darwin in the 1830s and inception of Darwin's theory, inspired his theory of evolution by means of natural selection. All of these islands are protected as part of Ecuador's Galápagos National Park and Galápagos Marine Reserve, Marine Reserve. Thus far, there is no firm evidence that Polynesian expansion, Polynesians or the indigenous peoples of South America, Indigenous pe ...

Santiago De Compostela
Santiago de Compostela, simply Santiago, or Compostela, in the province of Province of A Coruña, A Coruña, is the capital of the autonomous communities of Spain, autonomous community of Galicia (Spain), Galicia, in northwestern Spain. The city has its origin in the shrine of Saint James the Great, now the Cathedral of Santiago de Compostela, as the destination of the Way of St. James, a leading Catholic pilgrimage route since the 9th century. In 1985, the city's Old Town was designated a UNESCO World Heritage Site. Santiago de Compostela has a very mild climate for its latitude with heavy winter rainfall courtesy of its relative proximity to the prevailing winds from Atlantic Ocean, Atlantic low-pressure systems. Toponym According to Richard A. Fletcher, scholars now agree that the origin of the name Compostela comes from the Latin ''compositum tella'', meaning a well-ordered burial ground, possibly referring to an ancient burial ground on the site of the Church of Santiago de ...

Pyroclastic Rock
Pyroclastic rocks are clastic rocks composed of rock fragments produced and ejected by explosive volcanic eruptions. The individual rock fragments are known as pyroclasts. Pyroclastic rocks are a type of volcaniclastic deposit, which are deposits made predominantly of volcanic particles. 'Phreatic' pyroclastic deposits are a variety of pyroclastic rock that forms from volcanic steam explosions and they are entirely made of accidental clasts. 'Phreatomagmatic' pyroclastic deposits are formed from explosive interaction of magma with groundwater. The word ''pyroclastic'' is derived from the Greek , meaning fire; and , meaning broken. Unconsolidated accumulations of pyroclasts are described as tephra. Tephra may become lithified to a pyroclastic rock by cementation or chemical reactions as the result of the passage of hot gases (fumarolic alteration) or groundwater (e.g. hydrothermal alteration and diagenesis) and burial, or, if it is emplaced at temperatures so hot that the soft gla ...

Holocene
The Holocene () is the current geologic time scale, geological epoch, beginning approximately 11,700 years ago. It follows the Last Glacial Period, which concluded with the Holocene glacial retreat. The Holocene and the preceding Pleistocene together form the Quaternary period. The Holocene is an interglacial period within the ongoing Ice age, glacial cycles of the Quaternary, and is equivalent to Marine isotope stages, Marine Isotope Stage 1. The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth#Axial tilt and seasons, Earth's obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including Recorded history, all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban culture, urban living in the present. The human impact on modern-era Earth and its ecosystems may be considered of global significance for th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a Natural satellite, moon onto its surface. Lava may be erupted at a volcano or through a Fissure vent, fracture in the Crust (geology), crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is often also called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. Etymology The word ''lava'' comes from Ital ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Viscosity
Viscosity is a measure of a fluid's rate-dependent drag (physics), resistance to a change in shape or to movement of its neighboring portions relative to one another. For liquids, it corresponds to the informal concept of ''thickness''; for example, syrup has a higher viscosity than water. Viscosity is defined scientifically as a force multiplied by a time divided by an area. Thus its SI units are newton-seconds per metre squared, or pascal-seconds. Viscosity quantifies the internal friction, frictional force between adjacent layers of fluid that are in relative motion. For instance, when a viscous fluid is forced through a tube, it flows more quickly near the tube's center line than near its walls. Experiments show that some stress (physics), stress (such as a pressure difference between the two ends of the tube) is needed to sustain the flow. This is because a force is required to overcome the friction between the layers of the fluid which are in relative motion. For a tube ...

Floreana Island
Floreana Island () is a southern island in Ecuador's Galápagos Archipelago. The island has an area of . It was formed by volcanic eruption. The island's highest point is Cerro Pajas at , which is also the highest point of the volcano like most of the smaller islands of Galápagos. The island has a population of about 100. Names Floreana, sometimes written as Floriana, is named in honor of Juan José Flores, the first president of Ecuador. It was during Flores's presidency that Ecuador took possession of the archipelago. The island was previously known in Spanish as Mercedes Island (), sometimes corrupted to Mascarenas,. in honor of Flores's wife Mercedes Jijón. It was also known as Santa Maria, after the Virgin Mary and the '' Santa María'', one of Christopher Columbus's ships during his initial voyage. Pinta Island similarly remembers another one of his ships. The English pirate William Ambrosia Cowley did not apparently chart or name this island in his 17th-century ac ...

Coronation Of The British Monarch
The coronation of the monarch of the United Kingdom is an initiation ceremony in which they are formally invested with regalia and crowned at Westminster Abbey. It corresponds to the coronations that formerly took place in other European monarchies, which have all abandoned coronations in favour of inauguration or enthronement ceremonies. A coronation is a symbolic formality and does not signify the official beginning of the monarch's reign; ''de jure'' and ''de facto'' his or her reign commences from the moment of the preceding monarch's death or abdication, maintaining legal continuity of the monarchy. The coronation usually takes place several months after the death of the monarch's predecessor, as it is considered a joyous occasion that would be inappropriate while mourning continues. This interval also gives planners enough time to complete the required elaborate arrangements. The coronation of Charles III and Camilla, most recent coronation took place on 6 May 2023 to crown ...

William Ambrosia Cowley
William Ambrosia Cowley, also known as Ambrose Cowley and Captain Cowley, was a 17th-century English people, English buccaneer who surveyed the Galápagos Islands during his 1683–1686 circumnavigation of the world while serving under several captains such as John Eaton (pirate), John Eaton, John Cook (pirate), John Cook, and later Edward Davis (buccaneer), Edward Davis. Cowley drafted the first chart of the islands in 1684, first published with the account of his voyage in 1699. In his diary he reported the discovery of the phantom island, phantom Pepys Island, allegedly situated north of the Falkland Islands, prompting a number of mariners to look in vain for the nonexistent rock.
