An illustration of continental drift
Professor Iain Stewart cuts up a world map and shows how the land masses can fit together. This demonstration shows why geologists began to believe that land masses had once been joined together, then moved apart in the process known as continental drift.
Use as an introduction to plate tectonics. Pupils could be given a photocopied map to try it for themselves. Expand on the ideas of plates moving in relation to each other by discussing features such as fold mountains and ocean trenches.
This could be used with other extracts from the 'Men of Rock' series to understand how recent many modern geological theories are.
