plate boundaries Flashcards

1
Q

features of a destructive plate boundary

A

oceanic crust subducted under continental by slab pull (due to higher density), friction causes earthquake and in the subduction zone magma is heated and rises to fill the gap

Q

costructive plate boundary features

A

mid atlantic ridges are created as plate diverge, so new litosphere is created through gaps created
