Volcano Boarding
Volcano boarding or volcano surfing is a sport performed on the slopes of a volcano. One of the most popular places for the activity is the Cerro Negro near Leon in western Nicaragua. Riders hike up the volcano and slide down, sitting or standing, on a thin plywood or metal board. The sport is also practiced on Mount Yasur on Tanna, Vanuatu, Mount Bromo in Indonesia, and very few other locations. Volcano boarding can be an extreme sport. Potential dangers include falling and getting cut by the rough volcanic ash, breathing poisonous gasses, contracting histoplasmosis (otherwise known as "caver's disease"), or being hit by flying molten lava. Protective gear, including jumpsuits and goggles, is often used. Cerro Negro is also an active volcano, although the last eruption was in 1999. Mount Yasur is far more active and more dangerous, with volcanic eruptions occurring every day. Sandboarding, a similar activity performed on sand dunes, was established in the 1970s and 1980s: Derek ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano Boarding Cerro Negro
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 ...

Sand 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 san ...

Boardsports
Boardsports are active outdoor sports that are played with some sort of board as the primary equipment. These sports take place on a variety of terrain, from paved flat-ground and snow-covered hills to water and air. Most boardsports are considered action sports or extreme sports, and thus often appeal to youth. Some board sports were marginalized in the past. However, many board sports are gaining mainstream recognition, and with this recognition have enjoyed wider broadcast, sponsorship and inclusion in institutional sporting events, including the Olympic Games. Surfing is the first known boardsport, originating from Polynesian culture. Skateboarding was then invented by surfers looking to "surf" on land. It is hard to estimate when most boardsports were "invented" because people have been making homemade versions throughout history. For example, it is not hard to conceive of a person, who is familiar with the concept of skiing or sledding, standing sideways on a plank of wood an ...

X Games
The X Games are an annual extreme sports event organized, produced and broadcast by ESPN. Coverage is also shown on ESPN's sister network, ABC. The inaugural X Games were held during the summer of 1995 in Providence and Newport, Rhode Island, United States. Participants compete to win bronze, silver, and gold medals, as well as prize money. The competition often features new tricks such as Tony Hawk's 900 (skateboarding trick), 900 in skateboarding, Shaun White's Double McTwist 1260 in snowboard, Dave Mirra’s Double Backflip in BMX, Travis Pastrana's Double Backflip in freestyle motocross, Heath Frisby's first snowmobile frontflip, Chuck Carothers's first body varial in Moto X Best Trick, Henrik Harlaut's first nose-butter triple cork in Ski Big Air, Gus Kenworthy's first switch triple rodeo in a ski slopestyle competition and Torstein Horgmo's first landed triple cork in a snowboard competition. Concurrent with competition is the "X Fest" sports and music festival, which off ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extreme Sports
Action sports, adventure sports or extreme sports are activities perceived as involving a high degree of risk. These activities often involve speed, height, a high level of physical exertion and highly specialized gear. Extreme tourism overlaps with extreme sport. The two share the same main attraction, " adrenaline rush" caused by an element of risk, and differ mostly in the degree of engagement and professionalism. Definition The definition of extreme sports is not exact and the origin of the terms is unclear, but it gained popularity in the 1990s when it was picked up by marketing companies to promote the X Games and when the Extreme Sports Channel and Extreme International launched. More recently, the commonly used definition from research is "a competitive (comparison or self-evaluative) activity within which the participant is subjected to natural or unusual physical and mental challenges such as speed, height, depth or natural forces and where fast and accurate cogniti ...

Snowboarding
Snowboarding is a recreational and competitive activity that involves descending a snow-covered surface while standing on a snowboard that is almost always attached to a rider's feet. It features in the Winter Olympic Games and Winter Paralympic Games. Snowboarding was developed in the United States, inspired by skateboarding, sledding, surfing, and skiing. It became popular around the globe, and was introduced as a Winter Olympic Sport at Nagano in 1998 and featured in the Winter Paralympics at Sochi in 2014. , its popularity (as measured by equipment sales) in the United States peaked in 2007 and has been in a decline since. History The first snowboards were developed in 1965 when Sherman Poppen, an engineer in Muskegon, Michigan, invented a toy for his daughters by fastening two skis together and attaching a rope to one end so he would have some control as they stood on the board and glided downhill. Dubbed the "snurfer" (combining snow and surfer) by his wife Nancy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiian Lava Sledding
Hawaiian lava sledding ( Hawaiian: hee hōlua, "sled surfing") is a traditional sport of the Native Hawaiians. Similar to wave surfing, hee hōlua involves the use of a narrow ( long, wide) wooden sled (''papa hōlua''). The sled is used standing up, lying down, or kneeling, to ride down man-made or naturally occurring courses (''kahua hōlua)'' of rock, often reaching speeds of or greater. In the past, Hawaiian lava sledding was considered both a sport and a religious ritual for honoring the gods. Sleds Papa hōlua are composed of a pair of runners and a superstructure (platform). The runners are made from hard native woods, traditionally that of kauila (''Alphitonia ponderosa'' or ''Colubrina oppositifolia''), uhiuhi (''Caesalpinia kavaiensis''), or māmane (''Sophora chrysophylla''). The runners have up-curved fore edges, straight aft edges, and rounded lower edges. Crosspieces keep the runners apart. The superstructure, two rails smaller in diameter than the runners an ...

Sandboarding
Sandboarding is a boardsport and extreme sport similar to snowboarding that involves riding across or down a sand dune while standing on a board, either with both feet strapped in or while standing loose, without bindings. Sandboarding can also be practised sitting down or lying on the belly or the back. It typically involves a sandboard, although it is also possible to use sleds, surfboards, a skateboard deck, or snowboards. Sandboarding has adherents throughout the world, but is most prevalent in desert areas or coastal areas with beach dunes. It is less popular than snowboarding, partly because it is very difficult to build a mechanised ski lift on a sand dune, meaning participants must walk or ride a dune buggy or all-terrain vehicle back to the top of the dune. On the other hand, dunes are normally available year-round as opposed to ski resorts, which are seasonal. Equipment The sandboard base is much harder than a snowboard, and is built mostly out of formica or laminex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
