Salt, also referred to as table salt or by its chemical formula NaCl (sodium chloride), is an ionic compound made of sodium and chloride ions. All life depends on its chemical properties to survive. It has been used by humans for thousands of years, from food preservation to seasoning. Salt's ability to preserve food was a founding contributor to the development of civilization. It helped eliminate dependence on seasonal availability of food, and made it possible to transport food over large distances. However, salt was often difficult to obtain, so it was a highly valued trade item, and was considered a form of currency by many societies, including Rome. According to Pliny the Elder, Roman soldiers were paid in salt, from which the word salary is derived, although this is disputed by historians. Many salt roads, such as the Via Salaria in Italy, had been established by the Bronze Age. All through history, availability of salt has been pivotal to civilization. In Britain, the s ...

Salt Road
A salt road (also known as a salt route, salt way, saltway, or salt trading route) refers to any of the Prehistory, prehistoric and Recorded history, historical trade routes by which essential salt was transported to regions that lacked it. From the Bronze Age (in the 2nd millennium BC) fixed transhumance routes appeared, like the Ligurian ''drailles'' that linked the maritime Liguria with the ''alpages'', long before any purposely-constructed roadways formed the overland routes by which salt-rich provinces supplied salt-starved ones. Roads The ''Via Salaria'', an ancient Roman road in Italy, eventually ran from Rome (from Porta Salaria in the Aurelian Walls) to ''Castrum Truentinum'' (Porto d'Ascoli) on the Adriatic coast - a distance of . A modern road by this name, part of the SS4 highway, runs from Rome to Osteria Nuova in Orvieto. The Old Salt Route, about , was a medieval route in northern Germany, linking Lüneburg (in Lower Saxony) with the port of Lübeck (in Schleswi ...

Piles Of Salt Salar De Uyuni Bolivia Luca Galuzzi 2006 A
Hemorrhoids (or haemorrhoids), also known as piles, are sinusoid (blood vessel), vascular structures in the anal canal. In their normal state, they are cushions that help with Human feces, stool control. They become a disease when swelling (medical), swollen or inflammation, inflamed; the unqualified term ''hemorrhoid'' is often used to refer to the disease. The signs and symptoms of hemorrhoids depend on the type present. Internal hemorrhoids often result in painless, bright red hematochezia, rectal bleeding when defecation, defecating. External hemorrhoids often result in pain and swelling in the area of the Human anus, anus. If bleeding occurs, it is usually darker. Symptoms frequently get better after a few days. A skin tag may remain after the healing of an external hemorrhoid. While the exact cause of hemorrhoids remains unknown, a number of factors that increase pressure in the abdomen are believed to be involved. This may include constipation, diarrhea, and sitting o ...

Natron Valley
Wadi El Natrun (Arabic: "Valley of Natron"; , "measure of the hearts") is a depression in northern Egypt that is located below sea level and below the Nile River level. The valley contains several alkaline lakes, natron-rich salt deposits, salt marshes and freshwater marshes. In Christian literature it is usually known as Scetis ( in Hellenistic Greek) or Skete (, plural in ecclesiastical Greek). It is one of the three early Christian monastic centers located in the Nitrian Desert of the northwestern Nile Delta. The other two monastic centers are Nitria and Kellia. Scetis, now called Wadi El Natrun, is best known today because its ancient monasteries remain in use, unlike Nitria and Kellia which have only archaeological remains. The desertified valley around Scetis in particular may be called the Desert of Scetis.. Fossil discoveries The area is one of the best known sites containing large numbers of fossils of large pre-historic animals in Egypt, and was known for t ...

Appalachia
Appalachia ( ) is a geographic region located in the Appalachian Mountains#Regions, central and southern sections of the Appalachian Mountains in the east of North America. In the north, its boundaries stretch from the western Catskill Mountains of New York, continuing south through the Blue Ridge Mountains and Great Smoky Mountains into northern Georgia (US state), Georgia, Alabama, and Mississippi, with West Virginia near the center, being the only state entirely within the boundaries of Appalachia. In 2021, the region was home to an estimated 26.3 million people. Since its recognition as a cultural region in the late 19th century, Appalachia has been a source of Appalachian stereotypes, enduring myths and distortions regarding the isolation, temperament, and behavior of its inhabitants. Early 20th-century writers often engaged in yellow journalism focused on Sensationalism, sensationalistic aspects of the region's culture, such as moonshining and #Feuds, clan feuding, p ...

Sink (geography)
An endorheic basin ( ; also endoreic basin and endorreic basin) is a drainage basin that normally retains water and allows no outflow to other external bodies of water (e.g. rivers and oceans); instead, the water drainage flows into permanent and seasonal lakes and swamps that equilibrate through evaporation. Endorheic basins are also called closed basins, terminal basins, and internal drainage systems. Endorheic regions contrast with open lakes (exorheic regions), where surface waters eventually drain into the ocean. In general, water basins with subsurface outflows that lead to the ocean are not considered endorheic; but cryptorheic. Endorheic basins constitute local base levels, defining a limit of the erosion and deposition processes of nearby areas. Endorheic water bodies include the Caspian Sea, which is the world's largest inland body of water. Etymology The term ''endorheic'' derives from the French word , which combines ( 'within') and 'flow'. Endorheic lakes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evaporite
An evaporite () is a water- soluble sedimentary mineral deposit that results from concentration and crystallization by evaporation from an aqueous solution. There are two types of evaporite deposits: marine, which can also be described as ocean deposits, and non-marine, which are found in standing bodies of water such as lakes. Evaporites are considered sedimentary rocks and are formed by chemical sediments. Formation Although all water bodies on the surface and in aquifers contain dissolved salts, the water must evaporate into the atmosphere for the minerals to precipitate. For this to happen, the water body must enter a restricted environment where water input into this environment remains below the net rate of evaporation. This is usually an arid environment with a small drainage basin fed by a limited input of water. When evaporation occurs, the remaining water is enriched in salts, and they precipitate after the water becomes saturated. Depositional environments ...

Sedimentary
Sedimentary rocks are types of rock formed by the cementation of sediments—i.e. particles made of minerals (geological detritus) or organic matter (biological detritus)—that have been accumulated or deposited at Earth's surface. Sedimentation is any process that causes these particles to settle in place. Geological detritus originates from weathering and erosion of existing rocks, or from the solidification of molten lava blobs erupted by volcanoes. The geological detritus is transported to the place of deposition by water, wind, ice or mass movement, which are called agents of denudation. Biological detritus is formed by bodies and parts (mainly shells) of dead aquatic organisms, as well as their fecal mass, suspended in water and slowly piling up on the floor of water bodies ( marine snow). Sedimentation may also occur when dissolved minerals precipitate from water solution. The sedimentary rock cover of the continents of the Earth's crust is extensive (73% of the ...

Halite
Halite ( ), commonly known as rock salt, is a type of salt, the mineral (natural) form of sodium chloride ( Na Cl). Halite forms isometric crystals. The mineral is typically colorless or white, but may also be light blue, dark blue, purple, pink, red, orange, yellow or gray depending on inclusion of other materials, impurities, and structural or isotopic abnormalities in the crystals. It commonly occurs with other evaporite deposit minerals such as several of the sulfates, halides, and borates. The name ''halite'' is derived from the Ancient Greek word for "salt", ἅλς (''háls''). Occurrence Halite dominantly occurs within sedimentary rocks where it has formed from the evaporation of seawater or salty lake water. Vast beds of sedimentary evaporite minerals, including halite, can result from the drying up of enclosed lakes and restricted seas. Such salt beds may be hundreds of meters thick and underlie broad areas. Halite occurs at the surface today in playas in reg ...
