Why plate boundaries move?
Because of convection currents
1 of 8
Convection Currents
Hot magma rises from the inner core to the magma, then moves sideways under the crust, then cools down and sinks and goes back to the core
2 of 8
Constructive, Divergent
Plates move apart they separate
3 of 8
Destructive, Convergent
Plates collide
4 of 8
Collision
Oceanic crust collides with oceanic crust and they push up against each other and form folded mountains, eg. Himalayas
5 of 8
Conservative, Transform
Plates slide past each other
6 of 8
Volcanoes
Constructive, DIVERGENT, Oceanic crust with Oceanic crust, they move apart magma rises volcano forms. DESTRUCTIVE, Convergent, oceanic crust subducts under the continental crust and melts pressure builds up in the magma chamber, eg. Etna
7 of 8
Earthquake
Conservative, TRANSFORM, Plate boundaries pass each other, eg. San Andreas Fault
