a graph displaying all earthquakes for the past 30 years
6
Tsunamis are caused by
Subduction zones
Movement along plate boundaries
Earthquakes near/in water
Volcanoes
7
Subduction occurs when
oceanic crust is pushed below continental crust
continental and oceanic crust collide forming volcanoes
continental crust sinks below oceanic crust
oceanic crust overlaps continental crust
8

Convection Current
Converging Current
Subduction Current
Magma Recycling
13
Pasty Lava can be identified by
more violent eruptions

Do you think you know enough about this topic for your test?
I don't feel like I know enough, Yet
I need some help understanding this topic and will ask Ms. B
I have a pretty good understanding but I need to study more
Yes! I feel like I could sit the test now!
