PMT - slab pull

Question 1

what is slab pull? basic version

Answer 1

when a plate subducts under another

sinking into the mantle pulling the rest of the plate with it causing further subduction

Question 2

explain how the process of slab pull works

Answer 2

at the convergent plate boundary a oceanic plate meets a continental plate

the denser oceanic plate subducts beneath the lighter continental plate

due to gravity the oceanic plate sinks further into the mantle downwards

Question 3

what does slab pull explain?

Answer 3

why some plates move more quickly than others

plates with larger subduction zones eg the pacific plate moves faster as the slab pull effect is stronger

Question 4

what does the force of slab pull create?

Answer 4

volcanism

earthquakes
