The story of Northern Ireland's rocks is one of a journey through space and time, as our seemingly unchanging earth has altered its appearance as land masses come and go and physically move their position. What is now the solid land forming Northern Ireland tells complex history as this part of the earth has moved through many different climatic zones, sometimes occurring as dry land, at other times submerged below past oceans.
