The movement of plates

Oceanic crust

Continental crust​​

Plate margins

underneath the oceans

can be subducted

It is denser than continental crust

under land masses or continents

older than oceanic crust

less often destroyed

Earthquakes are found along all types of plate margins

Volcanoes occur at constructive and destructive plate margins

Convergent Boundaries

Divergent Boundaries

Transform Boundaries

two plates collide

crust is destroyed

oceanic-oceanic

continental+continental

plates that separate

creates new crust

earthquakes

volcanoes

plates slide horizontally

collide they get stuck

rock breaking

earthquakes
