Across
- 4. form at divergent boundaries
- 6. molten rock that is housed in the mantle
- 7. currents in the upper mantle that allow the plates to move.
- 8. one plate slides under the other one
- 9. form at convergent boundaries where one plate is denser than the other
Down
- 1. move toward each other and collide
- 2. when two plates slide past each other going opposite directions
- 3. moves away from each other forming a gap between the two plates
- 5. most common at transform boundaries
- 6. form at convergent boundaries where both plates have the same density
