Form 2, you have been continuing your 'Earth Forces' unit of work this week by studying the theory of plate tectonics and continental drift. The image above (courtesy of USGS) shows the break up of the supercontinent of Pangea and the subsequent drift of the continents to their present day locations.You can read more about the theory of continental drift and about Alfred Wegener, the German scientisy who first proposed it here.
Click on the hyperlinked text to view again an animation of continental drift which you may have looked at in class. There is also a good animation of the convection currents in the mantle which cause the plates to move. Next week we will move on to looking at different types of plate boundaries.
