Udo Island
Udo, (also called U-island, since do means island) is located on the northeast of Seongsan-ri, off the coast of Jeju, South Korea. This is the largest of the islands included in Jeju City. Udo, literally "Cow Island" in Hanja, has this name because it looks like a cow lying down. The whole of Udo is a lava plateau and a fertile flatland where major agricultural products such as sweet potatoes, garlic, and peanuts are produced. There is a parasitic cone, called ''soeui meori oreum'' in native Korean or ''udubong'' (牛頭峰) in Hanja (both mean "Cow's Head Peak"), in the southeast. Tourism Udo is one of the most visited spots in Jeju Island. About a million people visit Udo every year. Thanks to the scenery, it became the location for a few Korean films. Especially, ''Seobinbaeksa'' located on the west-coast of Udo Island was created by Rhodolith Rhodoliths (from Greek for ''red rocks'') are colorful, unattached calcareous nodules, composed of crustose, benthic marine red ...

South Korea
South Korea, officially the Republic of Korea (ROK), is a country in East Asia, constituting the southern part of the Korea, Korean Peninsula and sharing a Korean Demilitarized Zone, land border with North Korea. Its western border is formed by the Yellow Sea, while its eastern border is defined by the Sea of Japan. South Korea claims to be the sole legitimate government of the entire peninsula and List of islands of South Korea, adjacent islands. It has a Demographics of South Korea, population of 51.75 million, of which roughly half live in the Seoul Capital Area, the List of metropolitan areas by population, fourth most populous metropolitan area in the world. Other major cities include Incheon, Busan, and Daegu. The Korean Peninsula was inhabited as early as the Lower Paleolithic period. Its Gojoseon, first kingdom was noted in Chinese records in the early 7th century BCE. Following the unification of the Three Kingdoms of Korea into Unified Silla, Silla and Balhae in the ...

Korean People
Koreans ( South Korean: , , North Korean: , ; see names of Korea) are an East Asian ethnic group native to the Korean Peninsula. Koreans mainly live in the two Korean nation states: North Korea and South Korea (collectively and simply referred to as just Korea). They are also an officially recognized ethnic minority in other Asian countries; such as China, Japan, Kazakhstan and Uzbekistan. Koreans also form sizeable communities in Europe, specifically in Russia, Germany, United Kingdom, and France. Over the course of the 20th century, Korean communities have also formed in the Americas (especially in the United States and Canada) and Oceania. As of 2021, there were an estimated 7.3 million ethnic Koreans residing outside Korea. Etymology South Koreans refer to themselves as Hanguk-in(Korean: 한국인, Hanja: 韓國人) or Hanguk-saram (''Korean: 한국 사람''), both of which mean "people of the Han". When including members of the Korean diaspora, Koreans often use ...

Jeju City
Jeju City ( ko, 제주시, Jeju-si; ) is the capital of the Jeju Province in South Korea and the largest city on Jeju Island. The city is served by Jeju International Airport ( IATA code CJU). Located on an island off the Korean Peninsula, Jeju has mild, warm weather during much of the year. The city is a well-known resort, with prestigious hotels and public casino facilities. In 2011, 9.9 million passengers flew between the two cities of Seoul and Jeju, making the Gimpo–Jeju route the world's busiest passenger air route. Jeju welcomes over ten million visitors every year, mainly from the South Korean mainland, Japan, and China. The population of Jeju City is 486,306 people and 205,386 households (244,153 men and 242,153 women, February 2019). The population density is 470.03 (per square km, 2015). History The area of the city has played a central role in Jeju since before recorded history. The Samseonghyeol, holes from which the three ancestors of the Jeju people are s ...

Sino-Korean Vocabulary
Sino-Korean vocabulary or Hanja-eo () refers to Korean words of Chinese origin. Sino-Korean vocabulary includes words borrowed directly from Chinese, as well as new Korean words created from Chinese characters, and words borrowed from Sino-Japanese vocabulary. Many of these terms were borrowed during the height of Chinese-language literature on Korean culture. Anywhere from 30-60 percent of Korean words are of Chinese character origin. Many of these words have also been truncated or altered for the Korean language. History The use of Chinese and Chinese characters in Korea dates back to at least 194 BCE. While Sino-Korean words were widely used during the Three Kingdoms period, they became even more popular during the Silla period. During this time, male aristocrats changed their given names to Sino-Korean names. Additionally, the government changed all official titles and place names in the country to Sino-Korean. Sino-Korean words remained popular during the Goryeo and Jos ...

Lava Plateau
A volcanic plateau is a plateau produced by volcanism, volcanic activity. There are two main types: lava plateaus and pyroclastic plateaus. Lava plateau Lava plateaus are formed by highly fluid basaltic lava during numerous successive eruptions through numerous vents without violent explosions (quiet eruptions). These eruptions are quiet because of low viscosity of lava, so that it is very fluid and contains a small amount of trapped gases. The resulting sheet lava flows may be extruded from linear fissure vent, fissures or rifts or gigantic volcanic eruptions through multiple vents characteristic of the prehistoric era which produced giant flood basalts. Multiple successive and extensive lava flows cover the original landscape to eventually form a plateau, which may contain lava fields, cinder cones, shield volcanoes and other :Volcanic landforms, volcanic landforms. In some cases, a lava plateau may be part of a single volcano. An example is the massive Level Mountain shi ...

Parasitic Cone
A parasitic cone (also adventive cone or satellite cone) is the cone-shaped accumulation of volcanic material not part of the central vent of a volcano. It forms from eruptions from fractures on the flank of the volcano. These fractures occur because the flank of the volcano is unstable. Eventually, the fractures reach the magma chamber and generate eruptions called flank eruptions, which, in turn, produce a parasitic cone. A parasitic cone can also be formed from a dike or sill cutting up to the surface from the central magma chamber in an area different from the central vent. A peculiar example of multiple parasitic cones is Jeju Island in South Korea. Jeju features 368 " oreums" (; "mount"), which lie in a roughly lateral line on either side of the island's central dormant shield volcano Hallasan. See also *Flank crater A volcanic crater is an approximately circular depression in the ground caused by volcanic activity. It is typically a bowl-shaped feature containing ...

Rhodolith
Rhodoliths (from Greek for ''red rocks'') are colorful, unattached calcareous nodules, composed of crustose, benthic marine red algae that resemble coral. Rhodolith beds create biogenic habitat for diverse benthic communities. The rhodolithic growth habit has been attained by a number of unrelated coralline red algae, organisms that deposit calcium carbonate within their cell walls to form hard structures or nodules that resemble beds of coral. Rhodoliths do not attach themselves to the rocky seabed. Rather, they roll like tumbleweeds along the seafloor until they become too large in size to be mobilised by the prevailing wave and current regime. They may then become incorporated into a semi-continuous algal mat or form an algal build-up. While corals are animals that are both autotrophic (photosynthesize via their symbionts) or heterotrophic (feeding on plankton), rhodoliths produce energy solely through photosynthesis (i.e. they can only grow and survive in the photic zone of ...
