Quizplus · Accepted Answer

Chemical differentiation is the process by which heavier materials sank into the centers of terrestrial planets while lighter materials rose to the surfaces early in the history of these planets. Seafloor spreading and plate tectonics are processes related to the movement and formation of Earth's crust, while subduction is a process in which one tectonic plate is forced beneath another plate.
