Where does slab pull occur ?

Question

I mean actual examples on the earth

Answer 1

Sorry to burst your bubble, but but i think he wants to know where slab pull occurs, as in a place, eg nazca subduction zone..

And to answer the question, i havent the foggiest, but elizabeth's idea certainly let me know what slab pull is :D

Answer 2

under ocean earth quakes

Answer 3

As plates are destroyed as they subduct into the Earth, something must replace them on the surface.

This happens at the ocean rifts, where molten magma from the mantle wells up and creates new oceanic crust. These are thus termed 'constructive plate margins'They are marked  by the volcanically-active mountain ridge that runs along either side of the rift, which runs along all of the world's ocean floors.

Here, magma from the mantle wells up and creates these basalt ridges. With time, the rock cools and moves away from the ridge, to form the relatively flat sea floor which deepens with distance from the rift.

As the magma wells up, a number of forces act upon the plate on either side, including gravity, which pulls the new rock down the slope as lava extrudes from the top of the ridge. This force, which acts to push the plates apart, is nowhere near as strong as the 'slab pull' force, which acts in the subduction zones where plates are destroyed. However, it does contribute to the plate movement, by widening the gap between the two plates. This force is termed 'slab push'.
