Daikon Island
is a volcanic island in the middle of Sakumia, a brackish volcanic between Tottori and Shimane prefectures in Japan. Daikon Island is administered as part of Matsue, Shimane Prefecture. Daikon-jima takes its name from the daikon, the large, white East Asian radish. The island was, however, known throughout Japanese history as "Tako-shima", meaning "Octopus Island." Daikon Island is a shield volcano, a type of volcano composed of fluid lava flows. The island's highest elevation is a small volcano, Mount Ōzuka (). The base of the island composed of basalt. The surface of the island undulates slightly, and consists of a lava plateau. The surface of the island consists of a 2-meter deep layer of clay composed of volcanic ash. On the eastern end of the Daikon Island in the Osoe district there are lava tubes of up ). The lava tubes were formed by lava flows over the island. Lava tubes composed of secondary lava flows in the Terazu district of the island. They are designated Natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nakaumi
is a brackish lake located between Tottori and Shimane prefectures in Japan. The lake is enclosed by the Shimane Peninsula to the north and Yumigahama Peninsula to the east. It is the fifth largest lake in surface area in Japan. Nakaumi connects Lake Shinji (宍道湖 ''Shinji-ko'') and the Sea of Japan, and is surrounded by the municipalities Matsue, Yasugi, Yonago and Sakaiminato. There are two large islands in the lake, Daikon Island (大根島 ''Daikonjima'', literally "radish island") and Eshima Island (江島 ''Eshima'', "inlet island"). There are bridges (like the Eshima Ohashi Bridge) and roads that connect the east and west shores of the lake through the two islands. Nakaumi is a brackish lake because it is connected to the Sea of Japan by a short channel, the Sakai Channel, and lies so low that the tides reverse the flow of the rivers all the way into Lake Shinji. Nakaumi (中海) literally means "middle sea". Even though Nakaumi is a lake, it was likely named a ... [...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 ...

Volcanoes Of Honshū
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 pa ...

Islands Of Shimane Prefecture
An island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. The to ...

Edo Period
The or is the period between 1603 and 1867 in the history of Japan, when Japan was under the rule of the Tokugawa shogunate and the country's 300 regional '' daimyo''. Emerging from the chaos of the Sengoku period, the Edo period was characterized by economic growth, strict social order, isolationist foreign policies, a stable population, perpetual peace, and popular enjoyment of arts and culture. The period derives its name from Edo (now Tokyo), where on March 24, 1603, the shogunate was officially established by Tokugawa Ieyasu. The period came to an end with the Meiji Restoration and the Boshin War, which restored imperial rule to Japan. Consolidation of the shogunate The Edo period or Tokugawa period is the period between 1603 and 1867 in the history of Japan, when Japan was under the rule of the Tokugawa shogunate and the country's regional '' daimyo''.

Peony
The peony or paeony is a flowering plant in the genus ''Paeonia'' , the only genus in the family Paeoniaceae . Peonies are native to Asia, Europe and Western North America. Scientists differ on the number of species that can be distinguished, ranging from 25 to 40, although the current consensus is 33 known species. The relationships between the species need to be further clarified. Most are herbaceous perennial plants tall, but some are woody shrubs tall. They have compound, deeply lobed leaves and large, often fragrant flowers, in colors ranging from purple and pink to red, white or yellow, in late spring and early summer. The flowers have a short blooming season, usually only 7–10 days. Peonies are popular garden plants in temperate regions. Herbaceous peonies are also sold as cut flowers on a large scale, although generally only available in late spring and early summer. Description Morphology All Paeoniaceae are herbaceous perennials or deciduous shrubs, with t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ginseng
Ginseng () is the root of plants in the genus ''Panax'', such as Korean ginseng ('' P. ginseng''), South China ginseng ('' P. notoginseng''), and American ginseng ('' P. quinquefolius''), typically characterized by the presence of ginsenosides and gintonin. Ginseng is most commonly used in the cuisines and medicines of China and Korea. Although ginseng has been used in traditional medicine over centuries, modern clinical research is inconclusive about its medical effectiveness. There is no substantial evidence that ginseng is effective for treating any medical condition, and in the United States, for example, its use has not been approved by the US Food and Drug Administration (FDA) as a prescription drug. Although ginseng is commonly sold as a dietary supplement, inconsistent manufacturing practices for supplements have led to analyses showing that ginseng products may be contaminated with toxic metals or unrelated filler compounds, and its excessive use may have adverse effec ...

Lava Tube
A lava tube, or pyroduct, is a natural conduit formed by flowing lava from a volcanic vent that moves beneath the hardened surface of a lava flow. If lava in the tube empties, it will leave a cave. Formation A lava tube is a type of lava cave formed when a low-viscosity lava flow develops a continuous and hard crust, which thickens and forms a roof above the still-flowing lava stream. Tubes form in one of two ways: either by the crusting over of lava channels, or from pāhoehoe flows where the lava is moving under the surface. Lava usually leaves the point of eruption in channels. These channels tend to stay very hot as their surroundings cool. This means they slowly develop walls around them as the surrounding lava cools and/or as the channel melts its way deeper. These channels can get deep enough to crust over, forming an insulating tube that keeps the lava molten and serves as a conduit for the flowing lava. These types of lava tubes tend to be closer to the lava erupt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanic Ash
Volcanic ash consists of fragments of rock, mineral crystals, and volcanic glass, created during volcano, volcanic eruptions and measuring less than 2 mm (0.079 inches) in diameter. The term volcanic ash is also often loosely used to refer to all explosive eruption products (correctly referred to as ''tephra''), including particles larger than 2 mm. Volcanic ash is formed during explosive volcanic eruptions when dissolved gases in magma expand and escape violently into the atmosphere. The force of the gases shatters the magma and propels it into the atmosphere where it solidifies into fragments of volcanic rock and glass. Ash is also produced when magma comes into contact with water during phreatomagmatic eruptions, causing the water to explosively flash to steam leading to shattering of magma. Once in the air, ash is transported by wind up to thousands of kilometres away. Due to its wide dispersal, ash can have a number of impacts on society, including animal a ...
