Selfoss (waterfall)
Selfoss () is a waterfall on the river Jökulsá á Fjöllum in the north of Iceland. The river drops over a number of waterfalls over about 30 km before flowing into Öxarfjörður, a bay of the Arctic Sea. The river originates as melt water from the glacier Vatnajökull and therefore the water flow varies depending on the season, the weather and volcanic activity. A few hundred meters downstream of the -high waterfall is Dettifoss, the second-most powerful waterfall in Europe. Below the falls, the river passes through a gorge which is part of the Jökulsárgljúfur National Park.

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Jökulsá á Fjöllum
Jökulsá á Fjöllum (; "glacial river in the mountains") is the second longest river in Iceland (206 km). Its source is the Vatnajökull glacier. It flows into the Greenland Sea. Jökulsá á Fjöllum streams over the waterfalls Selfoss, Dettifoss, Hafragilsfoss, and , the second of which is the most powerful waterfall in Europe. The source of the river is in the Vatnajökull National Park, one of three national parks in Iceland. The river is located in the northeast of Iceland and forms the eastern boundary of Ódáðahraun, an extensive lava field. Its drainage basin is the largest in Iceland at 7,380 square kilometers. Glacial flooding Dettifoss drops into the Jökulsárgljúfur canyon, a feature which, along with the Ásbyrgi gorge, appears to have been formed by catastrophic glacial flooding caused by volcanic activity. The volcano in question was possibly Bárðarbunga, which has been identified as posing the risk of a similar event in the future. The larges ...

Waterfall
A waterfall is a point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling on to softer rock, which Erosion, erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls for years, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

Glacier
A glacier (; ) is a persistent body of dense ice that is constantly moving under its own weight. A glacier forms where the accumulation of snow exceeds its Ablation#Glaciology, ablation over many years, often Century, centuries. It acquires distinguishing features, such as Crevasse, crevasses and Serac, seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water. On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand.

Vatnajökull
Vatnajökull ( Icelandic pronunciation: , literally "Glacier of Lakes"; sometimes translated as Vatna Glacier in English) is the largest and most voluminous ice cap in Iceland, and the second largest in area in Europe after the Severny Island ice cap of Novaya Zemlya. It is in the south-east of the island, covering approximately 8% of the country. Size With an area of 7,900 km2, Vatnajökull is the second largest ice cap in Europe by volume (about 3,000 km3) and area (after the still larger Severny Island ice cap of Novaya Zemlya, Russia, which is in the extreme northeast of Europe). On 7 June 2008, it became a part of the Vatnajökull National Park. The average thickness of the ice is , with a maximum thickness of . Iceland's highest peak, Hvannadalshnúkur (), as part of the Öræfajökull, is in the southern periphery of Vatnajökull, near Skaftafell.

Volcano
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 ...

Europe
Europe is a large peninsula conventionally considered a continent in its own right because of its great physical size and the weight of its history and traditions. Europe is also considered a Continent#Subcontinents, subcontinent of Eurasia and it is located entirely in the Northern Hemisphere and mostly in the Eastern Hemisphere. Comprising the westernmost peninsulas of Eurasia, it shares the continental landmass of Afro-Eurasia with both Africa and Asia. It is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south and Asia to the east. Europe is commonly considered to be Boundaries between the continents of Earth#Asia and Europe, separated from Asia by the drainage divide, watershed of the Ural Mountains, the Ural (river), Ural River, the Caspian Sea, the Greater Caucasus, the Black Sea and the waterways of the Turkish Straits.

Jökulsárgljúfur National Park
Jökulsárgljúfur National Park () is a former national park situated in the north of Iceland around the river Jökulsá á Fjöllum. It lies to the north of the Dettifoss waterfall. On 7 June 2008, it became a part of the larger Vatnajökull National Park. Geography The area is of interest because of its chaotic canyon and volcanic mountains. Eight thousand years ago, volcanic fissures of the Askja volcanic system erupted directly underneath the river and glacial ice. This caused explosions and chaotic flooding. The center of the park was Vesturdalur with ''Hljóðaklettar'' (rock of echoes). ''Rauðhólar'' (red mountain) is of interest because of its special colouring due to iron oxidations. Another sight is the canyon of Ásbyrgi Ásbyrgi () is a glacial canyon and forest in the north of Iceland, located approximately east of Húsavík on the Diamond Circle road. The horseshoe-shaped depression is part of the Vatnajökull National Park and measures approximately 3.5 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waterfalls Of Iceland
Iceland is unusually suited for waterfalls (Icelandic: s. ''foss,'' pl. ''fossar''). This island country has a north Atlantic climate that produces frequent rain and snow and a near-Arctic location that produces large glaciers, whose summer melts feed many rivers. As a result, it is home to a number of large and powerful waterfalls.
