Between 400 million and 300 million years ago, parts of Northwest Europe, including much of Ireland, sank beneath a warm tropical sea. Great coral reefs formed in these waters, eventually creating the limestone that still makes up about 65 per cent of the area of the island.
What is the formation of rocks? There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changesu2014such as melting, cooling, eroding, compacting, or deformingu2014that are part of the rock cycle. Sedimentary rocks are formed from pieces of other existing rock or organic material.
Then, Why is it called Giant’s Causeway? The Giant’s Causeway gained its name due to the Irish myth surrounding its formation. Most likely because of the Causeway’s uniform and unusual shape, the people of Ancient Ireland created a fable to understand how the Causeway was created.
Is Giants Causeway a volcano? The Giant’s Causeway formed between 50 and 60 million years ago, when the region that now sits on the Antrim coastline was subject to intense volcanic activity. Molten basalt erupted through chalk beds and formed a lake of lava.

Between around 1.6 billion and 600 million years ago, at least two or three of these mighty supercontinents are thought to have existed, and as they formed and fragmented Ireland and North America were escorted on an epic voyage, at times resting north of the equator, at others being dragged almost as far as the South …
