PMT - slab pull Flashcards
1
Q
what is slab pull? basic version
A
when a plate subducts under another
sinking into the mantle pulling the rest of the plate with it causing further subduction
2
Q
explain how the process of slab pull works
A
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
3
Q
what does slab pull explain?
A
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
4
Q
what does the force of slab pull create?
A
volcanism
earthquakes
