San'in Kaigan Global Geopark
The is a geopark in Japan. The area was declared a Japanese Geopark in 2008, and a UNESCO Global Geopark in 2010. The underlying themes of the geopark are "geological features, the natural environment, people's lives, and the formation of the Sea of Japan". This geologically diverse area contains records of the process from when Japan was part of the Asian continent to its present-day formation of the Sea of Japan. People's lives are also diverse in this area because of its geodiversity. Area The San'in Kaigan Geopark is located to the northwest of Osaka and Kyoto and consists of Kyotango in Kyoto Prefecture, Toyooka, Kami, and Shin'onsen in Hyōgo Prefecture, Iwami, and a major part of Tottori in Tottori Prefecture. The geopark has an area of 2,458.44 square kilometers. Geosites The geopark includes sites that relate to the surrounding geomorphology and geology. Examples include the rice terraces and Tajima cattle grazing areas located on the gentle slopes form ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geomorphology
Geomorphology (from Ancient Greek: , ', "earth"; , ', "form"; and , ', "study") is the scientific study of the origin and evolution of topographic and bathymetric features created by physical, chemical or biological processes operating at or near Earth's surface. Geomorphologists seek to understand why landscapes look the way they do, to understand landform and terrain history and dynamics and to predict changes through a combination of field observations, physical experiments and numerical modeling. Geomorphologists work within disciplines such as physical geography, geology, geodesy, engineering geology, archaeology, climatology, and geotechnical engineering. This broad base of interests contributes to many research styles and interests within the field. Overview Earth's surface is modified by a combination of surface processes that shape landscapes, and geologic processes that cause tectonic uplift and subsidence, and shape the coastal geography. Surface processes co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dune
A dune is a landform composed of wind- or water-driven sand. It typically takes the form of a mound, ridge, or hill. An area with dunes is called a dune system or a dune complex. A large dune complex is called a dune field, while broad, flat regions covered with wind-swept sand or dunes with little or no vegetation are called ''ergs'' or ''sand seas''. Dunes occur in different shapes and sizes, but most kinds of dunes are longer on the stoss (upflow) side, where the sand is pushed up the dune, and have a shorter ''slip face'' in the lee side. The valley or trough between dunes is called a ''dune slack''. Dunes are most common in desert environments, where the lack of moisture hinders the growth of vegetation that would otherwise interfere with the development of dunes. However, sand deposits are not restricted to deserts, and dunes are also found along sea shores, along streams in semiarid climates, in areas of glacial outwash, and in other areas where poorly cemented sa ...

Shallots
The shallot is a botanical variety (a cultivar) of the onion. Until 2010, the (French red) shallot was classified as a separate species, ''Allium ascalonicum''. The taxon was synonymized with ''Allium cepa'' (the common onion) in 2010, as the difference was too small to justify a separate species. As part of the onion genus ''Allium'', its close relatives include garlic, scallions, leeks, chives, and the Chinese onion. Names The name "shallot" comes from Ashkelon, an ancient Canaanite city, where Classical-era Greeks believed shallots originated. The term ''shallot'' is usually applied to the French red shallot (''Allium cepa'' var. ''aggregatum'', or the ''A. cepa'' Aggregatum Group). It is also used for the Persian shallot or ''musir'' (''A. stipitatum'') from the Zagros Mountains in Iran and Iraq, and the French gray shallot ('' Allium oschaninii'') which is also known as ''griselle'' or "true shallot"; it grows wild from Central to Southwest Asia. The name ''shallot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Melons
A melon is any of various plants of the family Cucurbitaceae with sweet, edible, and fleshy fruit. The word "melon" can refer to either the plant or specifically to the fruit. Botanically, a melon is a kind of botanical berry, berry, specifically a "pepo (botany), pepo". The word ''melon'' derives from Latin ', which is the Latinisation (literature), latinization of the Ancient Greek, Greek (''mēlopepōn''), meaning "melon",. itself a compound of (''mēlon''), "apple, treefruit (''of any kind'')" and (''pepōn''), amongst others "a kind of gourd or melon". Many different cultivars have been produced, particularly of cantaloupes. History Melons originated in Africa or in the hot valleys of Southwest Asia, especially Iran and India, from where they gradually began to appear in Europe toward the end of the Western Roman Empire. Melons are known to have been grown by the ancient Egyptians. However, recent discoveries of melon seeds dated between 1350 and 1120 BCE in Nuragic sa ...

Onsen
In Japan, are the country's hot springs and the bathing facilities and traditional inns around them. As a volcanically active country, Japan has many onsens scattered throughout all of its major islands. There are approximately 25,000 hot spring sources throughout Japan that provide hot mineral water to about 3,000 genuine onsen establishments. Onsens come in many types and shapes, including and . Baths may be either publicly run by a municipality or privately, often as part of a hotel, ''ryokan'', or . The presence of an onsen is often indicated on signs and maps by the symbol ♨ or the kanji (''yu'', meaning "hot water"). Sometimes the simpler hiragana character ゆ (''yu''), understandable to younger children, is used. Traditionally, onsens were located outdoors, although many inns have now built indoor bathing facilities as well. Nowadays, as most households have their own bath, the number of traditional public baths has decreased, but the number of sightseeing ho ...

Handbag
A handbag, commonly known as a purse or pocketbook in North American English, is a handled medium-to-large bag used to carry personal items. Purse, handbag or pouch The term "purse" originally referred to a small bag for holding coins. In many English-speaking countries, it is still used to refer to a small money bag. A "handbag" is a larger accessory that holds objects beyond currency, such as personal items. American English typically uses the terms purse and handbag interchangeably. The term handbag began appearing in the early 1900s. Initially, it was most often used to refer to men's hand-luggage. Women's bags grew larger and more complex during this period, and the term was attached to the accessory. "Pocketbook" is another term for a woman's handbag that was most commonly used on the East Coast of the United States in the mid-twentieth century. Modern origin Early modern Europeans wore purses for one sole purpose: to carry coins. Purses were made of soft fabric or lea ...

Oriental Stork
The Oriental stork (''Ciconia boyciana''; Japanese: コウノトリ ''Konotori'') is a large, white bird with black wing feathers in the stork family Ciconiidae. Taxonomy The species was first described by Robert Swinhoe in 1873. It is closely related to and resembles the European white stork (''C. ciconia''), of which it was formerly often treated as a subspecies. Description It is typically larger than the white stork, at long, tall, a weight of and a wingspan of .''CRC Handbook of Avian Body Masses'' by John B. Dunning Jr. (Editor). CRC Press (1992), Unlike its more widespread cousin, the Oriental stork has red skin around its eye, with a whitish iris and black bill. Both sexes are similar. The female is slightly smaller than male. The young are white with orange bills. Distribution and habitat The Oriental stork is found in Japan, Manchuria, Korea and Siberia. It was once extirpated from Japan and the Korean Peninsula. However, in May 2007 a hatchling was reported ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chionoecetes Opilio
''Chionoecetes opilio'', a species of snow crab, also known as opilio crab or opies, is a predominantly epifaunal crustacean native to shelf depths in the northwest Atlantic Ocean and north Pacific Ocean. It is a well-known commercial species of ''Chionoecetes'', often caught with traps or by trawling. Seven species are in the genus ''Chionoecetes'', all of which bear the name "snow crab". ''C. opilio'' is related to '' C. bairdi'', commonly known as the tanner crab, and other crab species found in the cold, northern oceans. Anatomy Snow crabs have equally long and wide carapaces, or protective shell-coverings, over their bodies. Their tubercles, or the bodily projections on their shells, are moderately enclosed in calcium deposits, and they boast hooked setae, which are rigid, yet springy, hair-like organs on their claws. Snow crabs have a horizontal rostrum at the front of the carapace; the rostrum is basically just an extension of the hard, shell covering of the carapace and ...

Landslides
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the shear strength of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
