Öxarfjörður
Öxarfjörður () is a broad fjord in northeastern Iceland, situated between the Tjörnes and Melrakkaslétta headlands. Geography Öxarfjörður is encircled by mountain ranges to the west and east, and the Gjástykki lava fields and an area with sand deposited by the glacial river Jökulsá á Fjöllum in the south. The only village in the area is Kópasker with about 130 inhabitants. The Mid-Atlantic ridge runs through the western part of the fjord before going underwater again. Öxarfjörður went deeper inland in earlier geological times but the glacial river Jökulsá deposited sands from the highlands on a triangular area of about 300 km² called Sandur . Sandur is still trenched by the delta of Jökulsá which is constantly changing its riverbed. There are two big lakes on Sandur, Vikingavatn and Skjálftavatn , the latter one formed by an earthquake in 1976, over the course of which some houses in the area were destroyed. Economy The economy of the area is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kópasker
Kópasker () is a small village with approximately 120 inhabitants in the municipality of Norðurþing, situated on the eastern shore of Öxarfjörður in northeast Iceland. Kópasker (church 1).jpg, Church of Kópasker: ''Snartarstaðarkirkja'' KópaskerGeneralView.jpg, General view Overview The first residential house in Kópasker, Bakki, was built in 1912 by Árni Ingimundarson. Bakki burned down in 1988. Kópasker grew around the operation of the Co-op, providing services to local agriculture and fisheries.

Tjörnes
Tjörnes () is a peninsula situated at the northeast of Iceland, between the fjords of Öxarfjörður and Skjálfandi.

Salmon
Salmon () is the common name for several list of commercially important fish species, commercially important species of euryhaline ray-finned fish from the family (biology), family Salmonidae, which are native to tributary, tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus ''Oncorhynchus'') basin. Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen. Salmon are typically fish migration, anadromous: they hatch in the gravel stream bed, beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn (biology), spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run ma ...

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 km in length and over 1 km wide. For more than half of its length, the canyon is divided through the middle by a distinctive rock formation 25 meters high called ''Eyjan'' (, "the Island"), from which a vast landscape is seen. The canyon's steep sides are formed by cliffs up to in height. Within in the canyon is a woodland of birch and willow. Between 1947 and 1977, a number of foreign tree species were introduced, including spruce, larch and pine. The small lake ''Botnstjörn'' is home to a variety of waterfowl species. Ásbyrgi was most likely formed by catastrophic glacial flooding of the river Jökulsá á Fjöllum after the last ice age, first 8–10,000 years ago, and then again some 3,000 years ago. The river has sin ... [...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 ...

Dettifoss
Dettifoss () is a waterfall in Vatnajökull National Park in Northeast Iceland, and is reputed to be the second most powerful waterfall in Europe after the Rhine Falls. Dettifoss is situated on the Jökulsá á Fjöllum river, which flows from the Vatnajökull glacier and collects water from a large area in Northeast Iceland. The sediment-rich runoff colours the water a greyish white. The falls are wide and have a drop of down to the canyon Jökulsárgljúfur.

Since 2008, Iceland has three national parks. Prior to 2008 there were four national parks in Iceland; in that year Jökulsárgljúfur and Skaftafell were merged and incorporated into Vatnajökull National Park.

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.

Geothermal Energy
Geothermal energy is the thermal energy in the Earth's crust which originates from the formation of the planet and from radioactive decay of materials in currently uncertain but possibly roughly equal proportions. The high temperature and pressure in Earth's interior cause some rock to melt and solid mantle to behave plastically. This results in parts of the mantle convecting upward since it is lighter than the surrounding rock. Temperatures at the core–mantle boundary can reach over 4000 °C (7200 °F). Geothermal heating, using water from hot springs, for example, has been used for bathing since Paleolithic times and for space heating since ancient Roman times. More recently geothermal power, the term used for generation of electricity from geothermal energy, has gained in importance. It is estimated that the earth's geothermal resources are theoretically more than adequate to supply humanity's energy needs, although only a very small fraction is currently being ...
