Lake Of Agnano
__NOTOC__ Lago di Agnano or Lake Agnano was a circular lake, some 6½ km in circumference, which occupied the crater of the extinct volcano of Agnano 8 km west of Naples, Italy. It was apparently not formed until the Middle Ages, as it is not mentioned by ancient writers; it was drained in 1870. On the south bank are the Stufe di San Germano, natural sulphureous vapor baths, and close by is the Grotta del Cane. From the floor of this cave warm carbonic acid gas Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transpar ... constantly rises to a height of : the fumes render a dog insensible in a few seconds.

Volcanogenic Lake
A volcanogenic lake is a lake formed as a result of volcanic activity. They are generally a body of water inside an inactive volcanic crater (crater lakes) but can also be large volumes of molten lava within an active volcanic crater (lava lakes) and waterbodies constrained by lava flows, pyroclastic flows or lahars in valley systems. The term volcanic lake is also used to describe volcanogenic lakes, although it is more commonly assigned to those inside volcanic craters. Volcanic crater lakes Lakes in calderas fill large craters formed by the collapse of a volcano during an eruption. Examples: *Crater Lake, Oregon, United States *Heaven Lake, China/North Korea *Lake Toba, Sumatra, Indonesia Lakes in maars fill small craters where an eruption deposited debris around a vent. Examples: *Lake Nyos, Northwest Region, Cameroon *Lac Pavin, Puy-de-Dôme, France *Soda Lakes, Nevada, United States Lava lakes These are some examples of rare lava lakes where molten lava in a volcano m ...

Former Lake
A former is an object, such as a template, Gauge block, gauge or cutting Die (manufacturing), die, which is used to form something such as a boat's Hull (watercraft), hull. Typically, a former gives shape to a structure that may have complex curvature. A former may become an integral part of the finished structure, as in an aircraft fuselage, or it may be removable, being using in the construction process and then discarded or re-used. Aircraft formers Formers are used in the construction of aircraft fuselage, of which a typical fuselage has a series from the nose to the empennage, typically perpendicular to the Flight control surfaces#Longitudinal_axis, longitudinal axis of the aircraft. The primary purpose of formers is to establish the shape of the fuselage and reduce the column length of stringers to prevent instability. Formers are typically attached to longerons, which support the skin of the aircraft. The "former-and-longeron" technique (also called stations and string ...

Extinct Volcano
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 plates slide ...

Agnano
Agnano is a suburb of Napoli, Italy, situated southwest of the city in the Campi Flegrei region. It was popular among both ancient Greeks and Romans and was famed for its hot sulphurous springs. History Lake Agnano formed in the Middle Ages in the volcanic crater but was drained in 1870 to increase arable land and reduce the habitat of the ''Anopheles'' mosquito, which carries the malaria parasite. The crater is now home to the Agnano hippodrome and the town. After World War II, Agnano was home to the U.S. Naval Support Activity consisting of the U.S. Naval Hospital, administrative offices, barracks, and two Department of Defense Education Activity schools: Naples Elementary School and Naples American High School. Sights The ruins of ancient thermal baths originally from the Greek period are visible although the existing structures date mainly from the Roman period of the 1st-2nd century AD. Magnificent mosaics and sculptures were discovered here. The remains are located in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naples
Naples (; it, Napoli ; nap, Napule ), from grc, Νεάπολις, Neápolis, lit=new city. is the regional capital of Campania and the third-largest city of Italy, after Rome and Milan, with a population of 909,048 within the city's administrative limits as of 2022. Its province-level municipality is the third-most populous metropolitan city in Italy with a population of 3,115,320 residents, and its metropolitan area stretches beyond the boundaries of the city wall for approximately 20 miles. Founded by Greeks in the first millennium BC, Naples is one of the oldest continuously inhabited urban areas in the world. In the eighth century BC, a colony known as Parthenope ( grc, Παρθενόπη) was established on the Pizzofalcone hill. In the sixth century BC, it was refounded as Neápolis. The city was an important part of Magna Graecia, played a major role in the merging of Greek and Roman society, and was a significant cultural centre under the Romans. Naples served a ...

Stufe Di San Germano
In Schenkerian theory, a scale-step (german: Stufe) is a triad (based on one of the diatonic scale degrees) that is perceived as an organizing force for a passage of music (in accordance with the principle of composing-out). In ''Harmony'', Schenker gives the following example and asserts that A scale-step triad is designated by an uppercase Roman numeral representing the scale degree of the root, much as in traditional "harmonic analysis" (see chord progression). Thus, in the above example (which is in G major G major (or the key of G) is a major scale based on G, with the pitches G, A, B, C, D, E, and F. Its key signature has one sharp. Its relative minor is E minor and its parallel minor is G minor. The G major scale is: Notable compositi ...), the G major triad that Schenker claims we perceive through the first two measures would be labelled "I". However, unlike traditional harmonic analyses, Schenker's theory is not concerned with the mere labelling of su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sulphur
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] |
Grotta Del Cane
The Cave of Dogs (Italian: ''Grotta del Cane'') is a cave near Naples, Italy. Volcanic gases seeping into the cave give the air inside a high concentration of carbon dioxide. Dogs held inside would faint; at one time this was a tourist attraction. Description The Cave of Dogs (Italian: ''Grotta del Cane'', literally "Cave of the Dog")) is a cave about ten metres deep on the eastern side of the Phlegraean Fields near Pozzuoli, Naples. Inside the cave is a fumarole that releases carbon dioxide of volcanic origin. The cave is thought to have been constructed in classical antiquity, possibly as a sudatorium; if so, the CO emissions must have been much lower at the time. It may have been known to Pliny the Elder, who, in his '' Natural History'' (written 77-79 AD), mentions a location near Pozzuoli where animals die from poisonous fumes. However, the first unambiguous reports about the cave only appear in the 16th century. It was a tourist attraction for travelers on the Grand T ...

Carbonic Acid Gas
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.
