This programme reviews the experimental evidence for drifting continents, an idea which caused a revolution in the Earth Sciences. Briefly these are (1)Paleoclimatic evidence for latitudinal drift ...(2)Paleomagnetic evidence from 'apparent polar wandering' curves (3)Fossil links between widely separated continents (4)Similar rocks and mountain chains on distant continents. The drift hypothesis is reinforced by the continued creation of new ocean floor at volcanic ridges and its destruction by subduction beneath ocean trenches. The programme shows the climatic evidence of tropical climates in the UK which led to our presently exploited resources of coal and oil. Extensive use is made of models and graphic animation to explain the dynamics of plate tectonics.
