Why is continental crust lower in density than seafloor crust?
A) Continental crust is made of rock, while seafloor crust has more metals. B) Continental crust is made from volcanic rock called basalt, which is lower in density than what the seafloor crust is made from. C) Continental crust is made from remelted seafloor crust and therefore only the lower-density material rises to form it. D) Continental crust is actually denser than seafloor crust. E) Seafloor crust is more compact due to the weight of the oceans, but it is made of the same material as the continental crust.
