The new ELI today is the last in our series of What drives the plates? - 'What drives the plates? Modelling slab pull; modelling and discussing the slab pull plate-driving mechanism in the classroom'
Different ways of modelling the slab pull plate-driving mechanism are used in classroom discussion. Seismic wave velocity measurements show that some subducting plates sink right down to near the mantle/core boundary, pulling the surface part of the plate behind them.
Many more activities about plate tectonics can be found on our website.
