Larderello 001
Larderello is a ''frazione'' of the ''comune'' of Pomarance, in Tuscany in central Italy, renowned for its geothermal productivity. Geography The region of Lardarello has experienced occasional phreatic eruptions, caused by explosive outbursts of steam trapped below the surface. The water is contained in metamorphic rocks where it is turned to steam which is then trapped beneath a dome of impermeable shales and clay. The steam escapes through faults in the dome and forces its way out in the hot springs. It possesses a dozen explosion craters 30–250 m in diameter. The largest is the Lago Vecchienna crater which last erupted around 1282, now filled by the Boracifero Lake. Larderello now produces 10% of the world's entire supply of geothermal electricity, amounting to 4,800 GWh per year and powering about a million Italian households. Its geology makes it uniquely conducive to geothermal power production, with hot granite rocks lying unusually close to the surface, produc ...

Spring (hydrology)
A spring is a point of exit at which groundwater from an aquifer flows out on top of Earth's crust (pedosphere) and becomes surface water. It is a component of the hydrosphere. 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 hydrostatic pressure. Their yield 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 groundwater table reaches above the surface level. Springs may also be formed as a result of karst topography, aquifers, or volcanic activity. Springs also have been observed on the ocean floor, spewing hot water directly into the ocean. Springs formed as a result of karst topography create karst springs, in which ground water travels through ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geysers Of Italy
A geyser (, ) is a spring characterized by an intermittent discharge of water ejected turbulently and accompanied by steam. As a fairly rare phenomenon, the formation of geysers is due to particular hydrogeological conditions that exist only in a few places on Earth. Generally all geyser field sites are located near active volcanic areas, and the geyser effect is due to the proximity of magma. Generally, surface water works its way down to an average depth of around where it contacts hot rocks. The resultant boiling of the pressurized water results in the geyser effect of hot water and steam spraying out of the geyser's surface vent (a hydrothermal explosion). A geyser's eruptive activity may change or cease due to ongoing mineral deposition within the geyser plumbing, exchange of functions with nearby hot springs, earthquake influences, and human intervention. Like many other natural phenomena, geysers are not unique to Earth. Jet-like eruptions, often referred to as cryog ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geological Type Localities
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Earth ...

Frazioni Of The Province Of Pisa
A ''frazione'' (plural: ) is a type of subdivision of a ''comune'' (municipality) in Italy, often a small village or hamlet outside the main town. Most ''frazioni'' were created during the Fascist era (1922–1943) as a way to consolidate territorial subdivisions in the country. In the autonomous region of the Aosta Valley, a ''frazione'' is officially called an ''hameau'' in French. Description Typically the term ''frazioni'' applies to the villages surrounding the main town (''capoluogo'') of a ''comune''. Subdivision of a ''comune'' is optional; some ''comuni'' have no ''frazioni'', but others have several dozen. The ''comune'' usually has the same name of the ''capoluogo'', but not always, in which case it is called a ''comune sparso''. In practice, most ''frazioni'' are small villages or hamlets, occasionally just a clump of houses. Not every hamlet is classified as a ''frazione''; those that are not are often referred to as ''località'', for example, in the telephone boo ...

Wairakei
Wairakei is a small settlement, and geothermal area a few kilometres north of Taupō, in the centre of the North Island of New Zealand, on the Waikato River. It is part of the Taupō Volcanic Zone and features several natural geysers, hot pools. boiling mud pools, and the Wairakei Power Station, a major geothermal electric power generating station. The station was the second large-scale geothermal facility worldwide, and was commissioned in 1958. It was listed in the book ''70 Wonders Of The Modern World'' published in 2000 by Reader's Digest to record ''The Eventful 20th Century''. The settlement, referred to as Wairakei Village, was constructed to house the workers of both the power station and the neighbouring Aratiatia hydro power station. From 31 October 2022 it had buses to Taupō, Mondays to Fridays. Demographics Statistics New Zealand describes Wairakei Village as a rural settlement, which covers .

New Zealand
New Zealand ( mi, Aotearoa ) is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and over 700 smaller islands. It is the sixth-largest island country by area, covering . New Zealand is about east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The country's varied topography and sharp mountain peaks, including the Southern Alps, owe much to tectonic uplift and volcanic eruptions. New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and then developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. In 1840, representatives of the United Kingdom and Māori chiefs ...

Leopold II, Grand Duke Of Tuscany
Leopold II( it, Leopoldo Giovanni Giuseppe Francesco Ferdinando Carlo, german: Leopold Johann Joseph Franz Ferdinand Karl, English: ''Leopold John Joseph Francis Ferdinand Charles''. (3 October 1797 – 29 January 1870) was Grand Duke of Tuscany from 1824 to 1859. He married twice; first to Maria Anna of Saxony, and after her death in 1832, to Maria Antonia of the Two-Sicilies. By the latter, he begat his eventual successor, Ferdinand. Leopold was recognised contemporarily as a liberal monarch, authorising the Tuscan Constitution of 1848, and allowing a degree of press freedom. The Grand Duke was deposed briefly by a provisional government in 1849, only to be restored the same year with the assistance of Austrian troops, who occupied the state until 1855. Leopold attempted a policy of neutrality with regard to the Second Italian War of Independence, but was expelled by a bloodless coup on 27 April 1859, just before the beginning of the war. The Grand Ducal family left for B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boric Acid
Boric acid, more specifically orthoboric acid, is a compound of boron, oxygen, and hydrogen with formula . It may also be called hydrogen borate or boracic acid. It is usually encountered as colorless crystals or a white powder, that dissolves in water, and occurs in nature as the mineral sassolite. It is a weak acid that yields various borate anions and salts, and can react with alcohols to form borate esters. Boric acid is often used as an antiseptic, insecticide, flame retardant, neutron absorber, or precursor to other boron compounds. The term "boric acid" is also used generically for any oxoacid of boron, such as metaboric acid and tetraboric acid . History Orthoboric acid was first prepared by Wilhelm Homberg (1652–1715) from borax, by the action of mineral acids, and was given the name ("sedative salt of Homberg"). However boric acid and borates have been used since the time of the ancient Greeks for cleaning, preserving food, and other activities. Molecular a ...
