Across
- 2. when a convergent plate is more dense than the other
- 4. at this boundary,plates move away from each other
- 6. lava under ground
- 7. boundary where plates move toward each other and collide
- 9. boundary where plates slide past each other
Down
- 1. also forms at divergent boundaries
- 2. zone at convergent boundaries
- 3. underground
- 5. happens at a convergent boundary
- 8. happens at a divergent boundary
