Nature on the Giant's Causeway

Nature on the Giant's Causeway

Fingal's Cave is formed by hexagonal jointed basalt columns within lava flows This type of cave was formed by sea erosion during the Paleocene and is structurally similar to the Giant's Causeway in Northern Ireland and Ulva Coastal caves can be found in a variety of source rocks from sedimentary to metamorphic to igneous but metamorphic caves are typically larger due to the stronger source rocks The cave features a large arched entrance filled with seawater The cave entrance during calm weather from April to September allows exploration from the inside appearing to frame the island of Iona across the water During the Paleocene it was a sea cave on the uninhabited island of Staffa in Scotland's Inner Hebrides

Fractures run perpendicular to the cooling surface. Fingal's Cave is a sea cave on the uninhabited island of Staffa in Scotland's Inner Hebrides renowned for its natural resonance These fractures gradually widen toward the center of the flow forming the long hexagonal columns seen in the wave-eroded cross-section today A similar hexagonal fracture pattern is found in dry cracks in mud Cooling on the upper and lower surfaces of the solidified lava results in contraction and fracture beginning with a blocky tetragonal pattern and transitioning to a regular hexagonal fracture pattern.

Several sites of natural wonder and beauty are represented. Fingal's Cave is the site of the giant Benandonner a legendary Scottish giant associated with the Giant's Causeway in Northern Ireland once the birthplace of the giant Finn The story of a Scottish giant and an Irish hero a battle to see who could resist the threat is depicted in the natural setting of Northern Ireland's Giant's Causeway A giant named Fionn McCumhall or Finn MacCool after defeating all the giants in Ireland challenged the remaining giants making a loud noise that reached the giant Nenandonner on the opposite coast. 

Benandonner accepted the challenge and built a passage across the sea to fight Benandonner and triumph This natural heritage site is located on the north coast of County Antrim near Bushmills in Northern Ireland United Kingdom almost 3 kilometers long each rock has a diameter of about 40-50 centimeters 1-2 meters high

but some are even larger The largest rock is up to 12 meters high covering an area of ​​about 70 hectares Inside is composed of more than 40,000 large basalt boulders shaped like pillars standing on the ground more than 40,000 small and large lined up like a giant walkway leading from the cliff down to the beach below Giant's causeway was first discovered in 1692 by the Bishop of Derry and was declared a World Heritage Site in 1986 Formed approximately 50-60 million years ago by lava from volcanoes that flooded the area into chalk When the lava cooled and hardened it contracted evenly horizontally causing the rocks to split into columns resembling dry cracked earth
