Tectonic Plates 1
In this type of boundary, plates are moving towards each other.
convergent plate boundaries
In this type of plate boundary, plates are moving apart
divergent plate boundaries
What is the thinnest part of the earth?
the crust
In this type of boundary, plates slide against each other
transform plate boundaries
Where do tectonic plates interact?
boundaries
What lies directly beneath the crust
the mantle
Divergent boundaries create what in the ocean?
