When oceanic and continental crust converge, the oceanic plate will dive beneath the continental plate. What best explains the results of this action?

• The oceanic crust is moved upward by the radiation of heat

• The oceanic crust will melt as it moves deeper in the earth.

• The continental crust will form a mountain range.

• The two crusts will form an ocean basin
