When you streach it apart it would be like magma comeing to the surface and that would cause a volcano.So when you strech it apart that causes convergent boundaries.When the convection currents in the magma moves that causes the plate to move.If you would have streach the candy and push it together it wo uld have fitted,like the earth now is moving. This is a picture of the edibile earth that I built by my self.It has the crust,mantle,inner mantle,outter mantle,inner core and outter core.It is how the earth would look if you went to the inner core,the inside.There is pressure in the earth and heat so you could not go to the inside.The reason it is this way is because the gramcraker is the crust,the choclate is the mantle, the marshmellow fluff is the oitter core and the wopper ball is the core.
