Tectonics Revision

Dear All Tonights session is on tectonic theory, so everything connected to plate tectonics, types of volcanoes, earthquake theory, hotspots and continental drift. Please submit questions in advance if you cannot make it alter, the session starts at 730, and will run for as long as we need to, as there was no work shop on tuesday lunchtime. Please remember, that yout questions do not appear automatically, only when I poublish them! So you may need to be patient as i organise your answers to make the session more logical.
