Columnar Jointing
Columnar jointing is a geological structure where sets of intersecting closely spaced fractures, referred to as Joint (geology), joints, result in the formation of a regular array of polygonal Prism (geometry), prisms, or columns. Columnar jointing occurs in many types of igneous rocks and forms as the rock cools and contracts. Columnar jointing can occur in cooling lava flows and ashflow tuffs (ignimbrites), as well as in some shallow intrusions. Columnar jointing also occurs rarely in sedimentary rocks if they have been heated by nearby hot magma. The columns can vary from 3 meters to a few centimeters in diameter, and can be as much as 30 meters tall. They are typically parallel and straight, but can also be curved and vary in diameter. An array of regular, straight, and larger-diameter columns is called a colonnade; an irregular, less-straight, and smaller-diameter array is termed an entablature. The number of sides of the individual columns can vary from 3 to 8, with 6 sides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Idaho
Idaho ( ) is a state in the Pacific Northwest region of the Western United States. To the north, it shares a small portion of the Canada–United States border with the province of British Columbia. It borders the states of Montana and Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. The state's capital and largest city is Boise. With an area of , Idaho is the 14th largest state by land area, but with a population of approximately 1.8 million, it ranks as the 13th least populous and the 7th least densely populated of the 50 U.S. states. For thousands of years, and prior to European colonization, Idaho has been inhabited by native peoples. In the early 19th century, Idaho was considered part of the Oregon Country, an area of dispute between the U.S. and the British Empire. It officially became U.S. territory with the signing of the Oregon Treaty of 1846, but a separate Idaho Territory was not organized until 1863, instead ...

Causeway
A causeway is a track, road or railway on the upper point of an embankment across "a low, or wet place, or piece of water". It can be constructed of earth, masonry, wood, or concrete. One of the earliest known wooden causeways is the Sweet Track in the Somerset Levels, England, which dates from the Neolithic age. Timber causeways may also be described as both boardwalks and bridges. Etymology When first used, the word ''causeway'' appeared in a form such as "causey way" making clear its derivation from the earlier form "causey". This word seems to have come from the same source by two different routes. It derives ultimately, from the Latin for heel, ''calx'', and most likely comes from the trampling technique to consolidate earthworks. Originally, the construction of a causeway utilised earth that had been trodden upon to compact and harden it as much as possible, one layer at a time, often by enslaved bodies or flocks of sheep. Today, this work is done by machines. The s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Irish Language
Irish ( Standard Irish: ), also known as Gaelic, is a Goidelic language of the Insular Celtic branch of the Celtic language family, which is a part of the Indo-European language family. Irish is indigenous to the island of Ireland and was the population's first language until the 19th century, when English gradually became dominant, particularly in the last decades of the century. Irish is still spoken as a first language in a small number of areas of certain counties such as Cork, Donegal, Galway, and Kerry, as well as smaller areas of counties Mayo, Meath, and Waterford. It is also spoken by a larger group of habitual but non-traditional speakers, mostly in urban areas where the majority are second-language speakers. Daily users in Ireland outside the education system number around 73,000 (1.5%), and the total number of persons (aged 3 and over) who claimed they could speak Irish in April 2016 was 1,761,420, representing 39.8% of respondents.

Staffa
Staffa ( gd, Stafa, , from the Old Norse for stave or pillar island) is an island of the Inner Hebrides in Argyll and Bute, Scotland. The Vikings gave it this name as its columnar basalt reminded them of their houses, which were built from vertically placed tree-logs. Staffa lies about west of the Isle of Mull; its area is and the highest point is above sea level. The island came to prominence in the late 18th century after a visit by Sir Joseph Banks. He and his fellow-travellers extolled the natural beauty of the basalt columns in general and of the island's main sea cavern, which Banks renamed 'Fingal's Cave'. Their visit was followed by those of many other prominent personalities throughout the next two centuries, including Queen Victoria and Felix Mendelssohn. The latter's ''Hebrides Overture'' brought further fame to the island, which was by then uninhabited. It is now in the care of the National Trust for Scotland.
