Q

what is the last thing that causes the ground to shake at a conservative margin?

A

The two plates suddenly slip past each other which cause both plates to move and as a result the ground may shake (earthquake)

Q

what’s the last thing that happens at a constructive plate margin to cause a volcano?

Q

what movement is at a destructive plate margin?

A

The oceanic plate slides beneath the continental plate. The point at which this happens is called a subduction zone.

Q

what happens during the movement of the destructive plates?

A

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

Q

what happens during the movement of the collision plates?

A

if two continental plates collide, neither can sink and so the land buckles upwards to form fold mountains.
