Cities Of Japan
A is a local administrative unit in Japan. Cities are ranked on the same level as and , with the difference that they are not a component of . Like other contemporary administrative units, they are defined by the Local Autonomy Law of 1947. City status Article 8 of the Local Autonomy Law sets the following conditions for a municipality to be designated as a city: *Population must generally be 50,000 or greater (原則として人口5万人以上) *At least 60% of households must be established in a central urban area (中心市街地の戸数が全戸数の6割以上) *At least 60% of households must be employed in commerce, industry or other urban occupations (商工業等の都市的業態に従事する世帯人口が全人口の6割以上) *Any other conditions set by prefectural ordinance must be satisfied (他に当該都道府県の条例で定める要件を満たしていること) The designation is approved by the prefectural governor and the Minister for Internal ...

Limestone
Limestone ( calcium carbonate ) is a type of carbonate sedimentary rock which is the main source of the material lime. It is composed mostly of the minerals calcite and aragonite, which are different crystal forms of . Limestone forms when these minerals precipitate out of water containing dissolved calcium. This can take place through both biological and nonbiological processes, though biological processes, such as the accumulation of corals and shells in the sea, have likely been more important for the last 540 million years. Limestone often contains fossils which provide scientists with information on ancient environments and on the evolution of life. About 20% to 25% of sedimentary rock is carbonate rock, and most of this is limestone. The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, . ''Magnesian limestone'' is an obsolete and poorly-defined term used variously for dolomite, for limes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gold Column At Akiyoshi Cave
Gold is a chemical element with the symbol Au (from la, aurum) and atomic number 79. This makes it one of the higher atomic number elements that occur naturally. It is a bright, slightly orange-yellow, dense, soft, malleable, and ductile metal in a pure form. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements and is solid under standard conditions. Gold often occurs in free elemental (native state), as nuggets or grains, in rocks, veins, and alluvial deposits. It occurs in a solid solution series with the native element silver (as electrum), naturally alloyed with other metals like copper and palladium, and mineral inclusions such as within pyrite. Less commonly, it occurs in minerals as gold compounds, often with tellurium (gold tellurides). Gold is resistant to most acids, though it does dissolve in aqua regia (a mixture of nitric acid and hydrochloric acid), forming a soluble tetrachloroaurate anion. Gold is i ...

Speleothem
A speleothem (; ) is a geological formation by mineral deposits that accumulate over time in natural caves. Speleothems most commonly form in calcareous caves due to carbonate dissolution reactions. They can take a variety of forms, depending on their depositional history and environment. Their chemical composition, gradual growth, and preservation in caves make them useful paleoclimatic proxies. Chemical and physical characteristics More than 300 variations of cave mineral deposits have been identified. The vast majority of speleothems are calcareous, composed of calcium carbonate (CaCO3) minerals (calcite or aragonite). Less commonly, speleothems are made of calcium sulfate (gypsum or mirabilite) or opal. Speleothems of pure calcium carbonate or calcium sulfate are translucent and colorless. The presence of iron oxide or copper provides a reddish brown color. The presence of manganese oxide can create darker colors such as black or dark brown. Speleothems can also be brown d ...

Crown Prince
A crown prince or hereditary prince is the heir apparent to the throne in a royal or imperial monarchy. The female form of the title is crown princess, which may refer either to an heiress apparent or, especially in earlier times, to the wife of the person styled crown prince. ''Crown prince'' as a descriptive term has been used throughout history for the prince who is first-in-line to a throne and is expected to succeed (i.e. the heir apparent), barring any unforeseen future event preventing this. In certain monarchies, a more specific substantive title A substantive title is a title of nobility or royalty acquired either by individual grant or inheritance. It is to be distinguished from a title shared among cadets, borne as a courtesy title by a peer's relatives, or acquired through marriage. ... may be accorded and become associated with the position of '' heir apparent'' (e.g. Prince of Wales in the United Kingdom or Prince of Asturias in the Spain, Kingdom of Spain) ...

Emperor Hirohito
Emperor , commonly known in English-speaking countries by his personal name , was the 124th emperor of Japan, ruling from 25 December 1926 until his death in 1989. Hirohito and his wife, Empress Kōjun, had two sons and five daughters; he was succeeded by his fifth child and eldest son, Akihito. By 1979, Hirohito was the only monarch in the world with the title "emperor". He was the longest-reigning historical Japanese emperor and one of the longest-reigning monarchs in the world. Hirohito was the head of state under the Meiji Constitution during Japan's imperial expansion, militarization, and involvement in World War II. Japan waged a war across Asia in the 1930s and 40s in the name of Hirohito, who was revered as a god. After Japan's surrender, he was not prosecuted for war crimes, as General Douglas MacArthur thought that an ostensibly cooperative emperor would help establish a peaceful Allied occupation, and help the U.S. achieve their postwar objectives.

Cave
A cave or cavern is a natural void in the ground, specifically a space large enough for a human to enter. Caves often form by the weathering of rock and often extend deep underground. The word ''cave'' can refer to smaller openings such as sea caves, rock shelters, and grottos, that extend a relatively short distance into the rock and they are called ''exogene'' caves. Caves which extend further underground than the opening is wide are called ''endogene'' caves. Speleology is the science of exploration and study of all aspects of caves and the cave environment. Visiting or exploring caves for recreation may be called ''caving'', ''potholing'', or ''spelunking''. Formation types The formation and development of caves is known as ''speleogenesis''; it can occur over the course of millions of years. Caves can range widely in size, and are formed by various geological processes. These may involve a combination of chemical processes, erosion by water, tectonic forces, microorgani ...
