      • the earths outer surface or crust is made up of a number of plates
        • heat from the outer core causes convection currents in the mantle which is like a very thick and sticky liquid

                                  • where two plates rub against each other, you will find an earthquake zone
                                • when these currents rise up to meet the crust they tend to drag the plates apart. this happens in the middle of the oceans, often you will find underwater volcanos or chains of islands such as hawaii
