Mount Esja
Esja, in Icelandic called Esjan, which means "the Esja" (), is a mountain situated in the south-west of Iceland, about ten kilometres north of Iceland's capital city ReykjavÃk. Esja is not a single mountain, but a volcanic mountain range, made from basalt and tuff. Etymology The name is likely related to an archaic word, , meaning rock flake or carving stone. In the ''Kjalnesinga saga'', there is a rich widow among Irish settlers named Esja, but it is likely that the woman's name is derived from the mountain and not vice versa. ''Esja'' can be used as a given name in Iceland. Formation Esja was built up at the end of the Pleistocene with the beginning of the Ice Age. During the warm periods lava flowed, and in the cold periods ridges of tuff were built up under the glacier. The western part of the mountain range is the oldest (about 3.2 million years) and the eastern part is the youngest (about 1.8 million years). The movements of the plate boundarie ...

ReykjavÃk
ReykjavÃk ( ; ) is the capital and largest city of Iceland. It is located in southwestern Iceland, on the southern shore of Faxaflói bay. Its latitude is 64°08' N, making it the world's northernmost capital of a sovereign state. With a population of around 131,136 (and 233,034 in the Capital Region), it is the centre of Iceland's cultural, economic, and governmental activity, and is a popular tourist destination. ReykjavÃk is believed to be the location of the first permanent settlement in Iceland, which, according to Landnámabók, was established by Ingólfr Arnarson in 874 CE. Until the 18th century, there was no urban development in the city location. The city was officially founded in 1786 as a trading town and grew steadily over the following decades, as it transformed into a regional and later national centre of commerce, population, and governmental activities. It is among the cleanest, greenest, and safest cities in the world. History According to lege ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratum
In geology and related fields, a stratum ( : strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either '' bedding surfaces'' or ''bedding planes''.Salvador, A. ed., 1994. ''International stratigraphic guide: a guide to stratigraphic classification, terminology, and procedure. 2nd ed.'' Boulder, Colorado, The Geological Society of America, Inc., 215 pp. . Prior to the publication of the International Stratigraphic Guide, older publications have defined a stratum as either being either equivalent to a single bed or composed of a number of beds; as a layer greater than 1 cm in thickness and constituting a part of a bed; or a general term that includes both ''bed'' and ''lamina''.Neuendorf, K.K.E., Mehl, Jr., J.P., and Jackson, J.A. , eds., 2005.

Volcanoes Of Iceland
:''The volcano system in Iceland that started activity on August 17, 2014, and ended on February 27, 2015, is Bárðarbunga.'' :''The volcano in Iceland that erupted in May 2011 is GrÃmsvötn.'' Iceland experiences frequent volcanic activity, due to its location both on the Mid-Atlantic Ridge, a divergent tectonic plate boundary, and over a hot spot. Nearly thirty volcanoes are known to have erupted in the Holocene epoch; these include Eldgjá, source of the largest lava eruption in human history. Volcanic systems and volcanic zones of Iceland Holocene volcanism in Iceland is mostly to be found in the ''Neovolcanic Zone'', comprising the Reykjanes Volcanic Belt (RVB), the West Volcanic Zone (WVZ), the Mid-Iceland Belt (MIB), the East Volcanic Zone (EVZ) and the North Volcanic Zone (NVZ). Two lateral volcanic zones play a minor role: Öræfi Volcanic Belt (ÖVB) and Snæfellsnes Volcanic Belt (SVB). Outside of the main island are the Reykjanes Ridge (RR), as part of the Mid-At ...

Mountains Of Iceland
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited Summit (topography), summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are Monadnock, isolated summits, but most occur in mountain ranges. Mountain formation, Mountains are formed through Tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosys ...

Mosfellsbær
Mosfellsbær (, colloquially Mosó) is a town in south-west Iceland, east of the country's capital, ReykjavÃk. The town of Mosfellsbær is a 15-minute drive from midtown ReykjavÃk. The district includes the Leiruvogur cove, which forms part of Kollafjörður fjord. Three rivers empty into the cove: Leirvogsá, KaldakvÃsl and Varmá. Mosfellsbær provides numerous opportunities for outdoor and leisure activities. There has been a systematic development of outdoor recreational areas for residents, their guests and tourists. Often called "the green town", the town enjoys thermal activity and a number of greenhouses have been built there. Since 1933 it has supplied the capital area with natural hot water for house heating, swimming pools, and other uses. The mountainous area around the town is visited for hiking, skiing, hunting and fishing for trout and char in the small lakes. Landscape The natural landscape of Mosfellsbær is rugged, and 80% of the district lies more than 100 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cairn
A cairn is a man-made pile (or stack) of stones raised for a purpose, usually as a marker or as a burial mound. The word ''cairn'' comes from the gd, cà rn (plural ). Cairns have been and are used for a broad variety of purposes. In prehistoric times, they were raised as markers, as memorials and as burial monuments (some of which contained chambers). In modern times, cairns are often raised as landmarks, especially to mark the summits of mountains. Cairns are also used as trail markers. They vary in size from small stone markers to entire artificial hills, and in complexity from loose conical rock piles to elaborate megalithic structures. Cairns may be painted or otherwise decorated, whether for increased visibility or for religious reasons. A variant is the inuksuk (plural inuksuit), used by the Inuit and other peoples of the Arctic region of North America. History Europe The building of cairns for various purposes goes back into prehistory in Eurasia, ranging in s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rhyolite
Rhyolite ( ) is the most silica-rich of volcanic rocks. It is generally glassy or fine-grained (aphanitic) in texture, but may be porphyritic, containing larger mineral crystals (phenocrysts) in an otherwise fine-grained groundmass. The mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Rhyolitic magma is extremely viscous, due to its high silica content. This favors explosive eruptions over effusive eruptions, so this type of magma is more often erupted as pyroclastic rock than as lava flows. Rhyolitic ash-flow tuffs are among the most voluminous of continental igneous rock formations. Rhyolitic tuff has been extensively used for construction. Obsidian, which is rhyolitic volcanic glass, has been used for tools from prehistoric times to the present day because it can be shaped to an extremely sharp edge. Rhyolitic pumice finds use as an abrasive, in concrete, and as a soil amendment. Description Rhyolite i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
