Tiber River
The Tiber ( ; ; ) is the List of rivers of Italy, third-longest river in Italy and the longest in Central Italy, rising in the Apennine Mountains in Emilia-Romagna and flowing through Tuscany, Umbria, and Lazio, where it is joined by the River Aniene, to the Tyrrhenian Sea, between Ostia (Rome), Ostia and Fiumicino. It Drainage basin, drains a basin estimated at . The river has achieved lasting fame as the main watercourse of the city of Rome, which was founded on its eastern banks. The river rises at Mount Fumaiolo in Central Italy and flows in a generally southerly direction past Perugia and Rome to meet the sea at Ostia (town), Ostia. The Tiber has advanced significantly at its mouth, by about , since Roman times, leaving the ancient port of Ostia Antica (archaeological site), Ostia Antica inland."Tiber River".

Fiumicino
Fiumicino () is a town and comune in the Metropolitan City of Rome, Lazio, central Italy, with a population of 80,500 (2019). It is known for being the site of Leonardo da Vinci–Fiumicino Airport, the busiest airport in Italy and the ninth-busiest in Europe, which serves Rome and much of central Italy. Etymology The name literally means ''little river''. The town of "Fiumicino" should not be confused with like-named Fiumicino, a small river near Rimini better known as the Rubicon river. Recent history The destroyer "Velos", in May 1973, (with a crew of 270 men in total) commanded by one of the pioneers of the movement, Admiral Nikos Pappas at the time, left the formation of vessels participating in a NATO exercise off the coast of Sardinia and rushed at the port of the city where seven officers (including the captain) and twenty-five petty officers requested political asylum from the Italian authorities, which, after many days of suffering, was granted.

Marble
Marble is a metamorphic rock consisting of carbonate minerals (most commonly calcite (CaCO3) or Dolomite (mineral), dolomite (CaMg(CO3)2) that have recrystallized under the influence of heat and pressure. It has a crystalline texture, and is typically not Foliation (geology), foliated (Layered intrusion, layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. The extraction of marble is performed by quarrying. Marble production is dominated by four countries: China, Italy, India and Spain, which account for almost half of world production of marble and decorative stone. Because of its high hardness and strong wear resistance, and because it will not be deformed by temperature, marble is often used in Marble sculpture, sculpture and construction. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Benito Mussolini
Benito Amilcare Andrea Mussolini (29 July 188328 April 1945) was an Italian politician and journalist who, upon assuming office as Prime Minister of Italy, Prime Minister, became the dictator of Fascist Italy from the March on Rome in 1922 until Fall of the Fascist regime in Italy, his overthrow in 1943. He was also of Italian fascism from the establishment of the Italian Fasces of Combat in 1919, until Death of Benito Mussolini, his summary execution in 1945. He founded and led the National Fascist Party (PNF). As a dictator and founder of fascism, Mussolini inspired the List of fascist movements, international spread of fascism during the interwar period. Mussolini was originally a socialist politician and journalist at the Avanti! (newspaper), ''Avanti!'' newspaper. In 1912, he became a member of the National Directorate of the Italian Socialist Party (PSI), but was expelled for advocating military intervention in World War I. In 1914, Mussolini founded a newspaper, ''Il P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level
Mean sea level (MSL, often shortened to sea level) is an mean, average surface level of one or more among Earth's coastal Body of water, bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and Navigation, marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to Calibration, calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead a long-term average of tide gauge readings at a particular reference location. The term ''above sea level'' generally refers to the height above mean sea level (AMSL). The term APSL means above present sea level, comparing sea levels in the past with the level today. Earth's radius at sea level is 6,378.137 km (3,963.191 mi) at the equator. It is 6,356.752 km (3,94 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beech
Beech (genus ''Fagus'') is a genus of deciduous trees in the family Fagaceae, native to subtropical (accessory forest element) and temperate (as dominant element of Mesophyte, mesophytic forests) Eurasia and North America. There are 14 accepted species in two distinct subgenera, ''Englerianae'' and ''Fagus''. The subgenus ''Englerianae'' is found only in East Asia, distinctive for its low branches, often made up of several major trunks with yellowish bark. The better known species of subgenus ''Fagus'' are native to Europe, western and eastern Asia and eastern North America. They are high-branching trees with tall, stout trunks and smooth silver-grey bark. The European beech ''Fagus sylvatica'' is the most commonly cultivated species, yielding a utility timber used for furniture construction, flooring and engineering purposes, in plywood, and household items. The timber can be used to build homes. Beechwood makes excellent firewood. Slats of washed beech wood are spread around ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spring (hydrosphere)
A spring is a natural exit point at which groundwater emerges from an aquifer and flows across the ground surface as surface water. It is a component of the hydrosphere, as well as a part of the water cycle. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and Hydrostatics#Hydrostatic pressure, hydrostatic pressure. A spring produced by the emergence of Geothermal activity, geothermally heated groundwater is known as a hot spring. The yield (hydrology), yield of spring water varies widely from a volumetric flow rate of nearly zero to more than for the biggest springs. Formation Springs are formed when groundwater flows onto the surface. This typically happens when the water table reaches above the surface level, or if the terrain depression (geology), depresses sharply. Springs may also be formed ...

Source (river Or Stream)
The headwater of a river or stream is the geographical point of its beginning, specifically where surface runoff water begins to accumulate into a flowing channel of water. A river or stream into which one or many tributary rivers or streams flows has many headwaters, these being all of the individual headwaters of its tributaries. Each headwater is one of the river or stream's sources, as it is the place where surface runoffs from rainwater, meltwater, or spring water begin accumulating into a more substantial and consistent flow that becomes a first-order tributary of that river or stream. The tributary with the longest channel of all the tributaries to a river or stream, such length measured from that tributary's headwater to its mouth where it discharges into the river or stream, is the main stem of the river or stream in question. Definition The United States Geological Survey (USGS) states that a river's "length may be considered to be the distance from the mouth to th ...

Tectonic Subsidence
Tectonic subsidence is the Subsidence, sinking of the Earth's Crust (geology), crust on a large scale, relative to crustal-scale features or the geoid. The movement of Plate tectonics, crustal plates and accommodation spaces produced by Fault (geology), faulting brought about subsidence on a large scale in a variety of environments, including passive margins, aulacogens, fore-arc basins, foreland basins, intercontinental basins and pull-apart basins. Three mechanisms are common in the tectonic environments in which subsidence occurs: extension, cooling and loading. Mechanisms Extension Where the lithosphere undergoes horizontal extension at a normal fault or rift, rifting center, the crust will stretch until faulting occurs, either by a system of Fault (geology)#Dip-slip faults, normal faults (which creates horst (geology), horsts and grabens) or by a system of Fault (geology)#Listric fault, listric faults. These fault systems allow the region to stretch, while also decreasin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Delta
A river delta is a landform, archetypically triangular, created by the deposition of the sediments that are carried by the waters of a river, where the river merges with a body of slow-moving water or with a body of stagnant water. The creation of a river delta occurs at the '' river mouth'', where the river merges into an ocean, a sea, or an estuary, into a lake, a reservoir, or (more rarely) into another river that cannot carry away the sediment supplied by the feeding river. Etymologically, the term ''river delta'' derives from the triangular shape (Δ) of the uppercase Greek letter delta. In hydrology, the dimensions of a river delta are determined by the balance between the watershed processes that supply sediment and the watershed processes that redistribute, sequester, and export the supplied sediment into the receiving basin. River deltas are important in human civilization, as they are major agricultural production centers and population centers. They can provide ...

Ostia Antica (archaeological Site)
Ostia Antica () is an ancient Roman city and the port of History of Rome, Rome located at the mouth of the Tiber. It is near modern Ostia (Rome), Ostia, southwest of Rome. Due to siltation, silting and the invasion of sand, the site now lies from the sea. The name ''Ostia'' (the plural of ''ostium'') derives from Latin ''os'' 'mouth'. Ostia is now a large Classical archaeology, archaeological site noted for the excellent preservation of its ancient buildings, magnificent frescoes and impressive mosaics. The city's decline after antiquity led to harbor deterioration, marshy conditions, and reduced population. Sand dunes covering the site aided its preservation. Its remains provide insights into a city of commercial importance. As in Pompeii, Ostia's ruins provide details about Roman urbanism that are not accessible within the city of Rome itself. History Origins Ostia may have been Rome's first ''colonia (Roman), colonia''. According to legend, Ancus Marcius, the fourth kings ...
