  • Most scientists believe that Earth’s crust is composed of plates. There are two kinds of crust. Oceanic crust is more dense, on average, than continental crust. Accordingly, what would most likely happen if a plate of oceanic crust and a plate of continental crust collided?

    The oceanic crust would sink below the continental crust.
    The oceanic crust would ride above the continental crust.
    The continental crust would sink below the oceanic crust.
    The continental crust would become thinner than the oceanic crust.
