1:1.5M scale 'Geology Through Climate Change' poster map covering UK mainland, Northern Ireland and Eire. This poster map shows the rocks of Britain and Ireland in a new way, grouped and coloured according to the environment under which they were formed. Photographs illustrate modern-day environments, alongside images of the typical rock types which are formed in them. The ages of the rocks are shown in a timeline, which also shows global temperatures and sea levels changing through time. The changing positions of Britain and Ireland as they drifted northwards through geological time are illustrated too. It was jointly produced by the BGS, the Geological Survey of Northern Ireland and the Geological Survey of Ireland. It has been endorsed by a range of teaching organisations including WJEC (previously the Welsh Joint Education Committee), OCR (Oxford Cambridge and RSA Examinations), The Association of Teaching Organisations of Ireland and the Earth Science Teachers Association. Although primarily intended as a teaching resource, the poster map will be of interest to anyone seeking to understand the imprint geological time has left in the rocks of our islands. This poster map is free, all you pay is the postage and packing.
