Ferdinandea Island
Ferdinandea Island (also Graham Island, Graham Bank or Graham Shoal; french: Ile Julia) is a certain volcanic island/seamount in the Mediterranean Sea near the island of Sicily that has, on more than one occasion, risen above the Mediterranean via volcanic action and soon thereafter been washed away. Since 300 BC this cycle of events has occurred four times. The top of the island is presently 6 metres below sea level. The island's most recent "appearance" occurred in July 1831, but then by January 1832 the portion of the island above sea level had been entirely washed away again by the wind and the waves of the Mediterranean Sea. The 1831 version of the island was first visited by the Sicilian customs official Michele Fiorini on 17 July 1831, who planted an oar there to claim the newly emerged island for the Kingdom of Sicily. Historical description of brief appearance of island. On 2 August 1831 Humphrey Fleming Senhouse, the captain of the first rate Royal Navy ship of ...

Map Of Graham Island
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Erosion
Erosion is the action of surface processes (such as water flow or wind) that removes soil, rock, or dissolved material from one location on the Earth's crust, and then transports it to another location where it is deposited. Erosion is distinct from weathering which involves no movement. Removal of rock or soil as clastic sediment is referred to as ''physical'' or ''mechanical'' erosion; this contrasts with ''chemical'' erosion, where soil or rock material is removed from an area by dissolution. Eroded sediment or solutes may be transported just a few millimetres, or for thousands of kilometres. Agents of erosion include rainfall; bedrock wear in rivers; coastal erosion by the sea and waves; glacial plucking, abrasion, and scour; areal flooding; wind abrasion; groundwater processes; and mass movement processes in steep landscapes like landslides and debris flows. The rates at which such processes act control how fast a surface is eroded. Typically, physical erosion procee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gustavo (ship)
Gustavo is the Latinate form of a Germanic male given name with respective prevalence in Portuguese, Spanish, and Italian. It has been a common name for Swedish monarchs since the reign of Gustav Vasa. It is derived from Gustav /ˈɡʊstɑːv/, also spelled Gustaf, of Old Swedish origin, meaning “staff of the Gods/Goths” or “great royal staff” or "staff of the Geats", derived from the Old Norse elements Gautr ("Geat") and stafr ("staff"). Other Swedish variants/derivatives: Gösta, Göstav, Gustafsson, Gustavsson. Such a name is also etymologically indicative of a Slavonic origin (through Swedish) from "Gostislav", a compound word from Old Slavic "Gost'" ("guest") and "slava" ("glory"). Other Slavonic variants/derivatives: Goslav, Gustaw, Gusti, Gustik, Gusty. Such a name in the United States also bears diminutive forms in English, which serve as nick names: Gus, Gussie, Gussy, Goose. To avoid confusion, note that these nick names are also commonly used for a different cl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brig
A brig is a type of sailing vessel defined by its rig: two masts which are both square rig, square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships. Brigs were prominent in the coasting coal trade of British waters. 4,395 voyages to London with coal were recorded in 1795. With an average of eight or nine trips per year for one vessel, that is a fleet of over 500 colliers trading to London alone. Other ports and coastal communities were also be served by colliers trading to Britain's coal ports. In the first half of the 19th century, the va ...

Sulfur
Sulfur (or sulphur in British English) is a chemical element with the symbol S and atomic number 16. It is abundant, multivalent and nonmetallic. Under normal conditions, sulfur atoms form cyclic octatomic molecules with a chemical formula S8. Elemental sulfur is a bright yellow, crystalline solid at room temperature. Sulfur is the tenth most abundant element by mass in the universe and the fifth most on Earth. Though sometimes found in pure, native form, sulfur on Earth usually occurs as sulfide and sulfate minerals. Being abundant in native form, sulfur was known in ancient times, being mentioned for its uses in ancient India, ancient Greece, China, and ancient Egypt. Historically and in literature sulfur is also called brimstone, which means "burning stone". Today, almost all elemental sulfur is produced as a byproduct of removing sulfur-containing contaminants from natural gas and petroleum.. Downloahere The greatest commercial use of the element is the production o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sciacca
Sciacca (; Greek language, Greek: ; Latin: Thermae Selinuntinae, Thermae Selinuntiae, Thermae, Aquae Labrodes and Aquae Labodes) is a town and ''comune'' in the province of Agrigento on the southwestern coast of Sicily, southern Italy. It has views of the Mediterranean Sea. History Thermae was founded in the 5th century BC by the Ancient Greece, Greeks, as its name suggests, as a thermal spa for Selinunte, 30 km distant, whose citizens came there to bathe in the sulphurous spring (hydrosphere), springs, still much valued for their medical properties, of Mount San Calogero which rises up behind the town. There is no account of the existence of a town on the site during the period of the independence of Selinunte, though the thermal waters would always have attracted some population to the spot. It seems to have been much frequented in the time of the Romans. At a later period they were called the Aquae Labodes or Larodes, under which name they appear in the Itineraries. Pliny the ...

Earthquake
An earthquake (also known as a quake, tremor or temblor) is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time period. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. The word ''tremor'' is also used for Episodic tremor and slip, non-earthquake seismic rumbling. At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground. When the epicenter of a large earthquake is located offshore, the seabed may be displaced sufficiently to cause ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantelleria
Pantelleria (; Sicilian: ''Pantiddirìa'', Maltese: ''Pantellerija'' or ''Qawsra''), the ancient Cossyra or Cossura, is an Italian island and comune in the Strait of Sicily in the Mediterranean Sea, southwest of Sicily and east of the Tunisian coast. On clear days Tunisia is visible from the island. Administratively Pantelleria's comune belongs to the Sicilian province of Trapani. The population of Pantelleria 2022 was 7,335 in 2022, according to istat.it. Description With an area of , Pantelleria is the largest volcanic satellite island of Sicily. The last eruption occurred below sea level in 1891, and today phenomena related to volcanic activity are present, such as hot springs and fumaroles. The highest peak, the ''Montagna Grande'', reaches above sea level. The islanders speak Pantesco, a dialect of Sicilian influenced by Arabic. Names The Carthaginians knew the island as ( xpu, 𐤉𐤓𐤍𐤌) or (). The Greek geographers recorded it as ''Kossyra'' ( grc, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seamount
A seamount is a large geologic landform that rises from the ocean floor that does not reach to the water's surface (sea level), and thus is not an island, islet or cliff-rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to in height. They are defined by oceanographers as independent features that rise to at least above the seafloor, characteristically of conical form.IHO, 2008. Standardization of Undersea Feature Names: Guidelines Proposal form Terminology, 4th ed. International Hydrographic Organization and Intergovernmental Oceanographic Commission, Monaco. The peaks are often found hundreds to thousands of meters below the surface, and are therefore considered to be within the deep sea. During their evolution over geologic time, the largest seamounts may reach the sea surface where wave action erodes the summit to form a flat surface. After they have subsided and sunk below the sea surface such flat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plate ...
