How did continental crust form on earth?
The crust, is the surface of the Earth; therefore on the top. The above is true, however it is slightly more complicated than this! Crust is formed at mid ocean ridges where magma rises to the surface as tectonic plates move apart. It is also formed (perhaps counter-intuitively) at destructive plate margins where volcanism occurs and the lava adds to the overlying crust. Oceanic sediments build up at the boundary of the continental crust as the oceanic slab scrapes against the overlying continental crust as it subducts (this is known as an accretionary prism).
