12 de abr. de 2018 · For centuries, the prevailing legend surrounding the Giant's Causeway in Northern Ireland was that Fionn Mac Cumhaill (Finn McCool), the mythical hunter-warrior of Irish mythology associated...
13 de abr. de 2018 · A TEAM of scientists from the University of Liverpool has made a breakthrough into how the unusual Giant’s Causeway rock formations were created. According to legend, the causeway was created by Irish giant Finn MacCool throwing chunks of the Antrim coast into the sea to build a route to Scotland.
Discover the amazing geological history of the Giant's Causeway, a natural wonder of hexagonal basalt columns in Northern Ireland. This article is part of the sciencefocusexplains series, where you can learn more about the world around you.
The Giant's Causeway (Irish: Clochán an Aifir) is an area of about 40,000 interlocking basalt columns, the result of an ancient volcanic fissure eruption. It is located in County Antrim on the north coast of Northern Ireland, about three miles (4.8 km) northeast of the town of Bushmills.. It was declared a World Heritage Site by UNESCO in 1986 and a national nature reserve by the Department ...
14 de nov. de 2019 · Scientists would have you believe that the Giant’s Causeway was formed 50 to 60 million years ago during a series of volcanic eruptions. The columns were formed when eruptions threw up molten basalt which formed a pool of lava. As this cooled and contracted, cracks appeared across the lava and formed dark, hexagonal stone steps.
Those rifts produced cracks, and up through those cracks came lots of molten rock and lava. Much later, erosion then caused rivers to form in the basalt. Then more lava came, which flowed through the river valleys. In this river valley, the Giant’s Causeway we think of today was formed.
