Plate Tectonics
Across
- 2. boundary where 2 plates move apart
- 4. occur at all plate boundaries
- 6. formed when 2 continental plates collide
- 9. the earth's surface is broken into pieces that float on molten rock; earthquakes, mountains,and volcanoes form
- 10. molten rock
- 12. boundary where 2 plates collide
Down
- 1. chunks of lithosphere
- 3. boundary where plates slide side by side
- 5. where 2 plates collide and the more dense plate is recycled in the mantle
- 7. deep crack in the earth
- 8. when new crust forms as 2 oceanic plates move apart
- 11. forms where 2 plates collide
