Alternatively, subducted oceanic crust may be able to pull adjacent continental crust down into the asthenosphere.

This proposed that mid-oceanic ridges represent regions where new oceanic crust is being generated by the upwelling of hot mantle material.

Continental lithosphere stands higher than oceanic lithosphere because continental crust is both of greater thickness and lower density than oceanic crust.

Basalts are the rocks which are formed at mid-ocean ridges, and which make up the entire oceanic crust.
