| 11. | A large continental block existed with oceanic crust subducting underneath it.
|
| 12. | Beneath the wedge are several seismic layers within the oceanic crust.
|
| 13. | They also found that the oceanic crust was much thinner than continental crust.
|
| 14. | Ocean island basalts are found on islands and volcanoes located on oceanic crust.
|
| 15. | Through subduction, oceanic crust and lithosphere returns to the convecting mantle.
|
| 16. | The oceanic crust is moving away from the Explorer Ridge to either side.
|
| 17. | The intrusions were formed when upwelling asthenosphere partially melted thick overlying oceanic crust.
|
| 18. | As the oceanic crust dives into trenches, the continental crust collects above them.
|
| 19. | The circulation of hydrothermal fluids through young oceanic crust causes chlorite, and serpentine, respectively.
|
| 20. | The oceanic crust is moving away from the East Pacific Rise to either side.
