Hotspots . . what are they?

 Today we consider 'Hotspots; modelling the movement of a plate across the globe'.

In this ELI a felt-tip pen and a piece of card are used to model the evidence of the movement of a tectonic plate over a fixed heat source in the Earth’s mantle.

Many related activities can be found in 'Plate tectonics' in our Earth energy / processes category.
