Updated 'mantle plume' activity

Because the science has moved on, we have just re-published an activity we first wrote in 2010. This includes all the latest thinking on this topic.

A “mantle plume” in a beaker – but not driving plates: mantle plumes ‘yes’ – but convection currents driving plates, probably ‘No’

This Earthlearningidea replaces A “mantle plume” in a beaker: modelling processes at a constructive (divergent) plate margin’, which was published when the convection current model of mantle drag was thought to be the main driving force of plate movement.
Many more activities relating to plate tectonics, including recent UPDATES can be found on our website.
