Today's new Earthlearningidea is an ELI+ activity - 'Melting and boiling – the influence of pressure; how does a reduction in pressure lower melting and boiling points?'
This ELI is a demonstration of the reduction of boiling point due to reducing the pressure. This provides an analogy with rocks melting at a lower temperature when the overlying pressure is reduced, notably at a divergent plate margin.
Other activities related to pressure or to plate tectonics can be found by using the search engine or alphabetical index on our website.
