Plate margins Flashcards
what movement is at conservative plate margins?
the plates are sliding past each other
what is a conservative plate margin like?
the plates are rock with jagged edges that snag against each other
what happens during the movement of the conservative plates?
the friction and pressure between the plates build until the plates can’t take the stress
what is the last thing that causes the ground to shake at a conservative margin?
The two plates suddenly slip past each other which cause both plates to move and as a result the ground may shake (earthquake)
what is the movement at constructive plate margins?
the plates move apart (diverge)
what happens during the movement of constructive plates?
the convection currents push apart (diverge) and cause a gap to form between the plates
what’s the last thing that happens at a constructive plate margin to cause a volcano?
magma rises up to fill the gap that is created between the 2 plates
what movement is at a destructive plate margin?
The oceanic plate slides beneath the continental plate. The point at which this happens is called a subduction zone.
what happens during the movement of the destructive plates?
The rocks catch against one another as the plates are not smooth surfaces. The pressure between the plates build until they can’t take the stress
what is the last thing that happens at a constructive plate margin to causes the earthquake?
the plates slip past each other which cause both plates to move and as a result the ground may shake (earthquake)
what movement are the plates going at collision plate margins?
the plates are colliding
what happens during the movement of the collision plates?
if two continental plates collide, neither can sink and so the land buckles upwards to form fold mountains.
