Geological time: Track 1


Geology is the scientific study of the Earth, its origin, structure, processes and composition. This album is concerned mainly with the interpretation of geological maps and the relationship between the landscape and underlying rocks. It reveals how the geological history of any area can be interpreted from a geological map. Dr Andrew Bell visits Morecambe Bay and the 'special' Siccar Point to investigate the rocks and stones in the area. This material is taken from The Open University course S260 Geology.
