Convergent Plate Boundaries

Back 22

Between two plates that are moving closer to each other

Hint 22

Front 23

Transform Plate Boundaries

Back 23

Between two plates that are sliding past each other

Hint 23

Front 24

Subduction

Back 24

One tectonic plate moves under another tectonic plate and sinks
