plate boundaries Flashcards
what are the types of crust in a divergent plate boundary
Oceanic and oceanic
what are the types of crust in a convergent plate boundary
Oceanic and continental
what are the types of crust in a collision plate boundary
continental and continental
what are the types of crust in a conservative plate boundary
continental and continental
what is the direction of plate movement in a divergent plate boundary
plates are moving apart, so magma escapes from the mantle below
what is the direction of plate movement in a convergent plate boundary
plates move towards eachother, the denser (thicker) oceanic crust is forced under the continental plate
what is the direction of plate movement in a collision plate boundary
magma from the mantle rises up to make new crust
what is the direction of plate movement in a conservative plate boundary
plates slide paste eachother at different speeds, but as they start to move friction occurs and they become stuck
