What is the relationship between plate tectonics and "seafloor spreading"? seafloor spreading is the force that moves the plates in earth's crust. when the plates in earth's crust become larger, then seafloor spreading occurs. the movement of plates in earth's crust is the cause of seafloor spreading. when seafloor spreading increases, then the movement of plates in earth's crust increases.

does this help? seafloor spreading. Seafloor spreading is a geologic process in which tectonic plates—large slabs of Earth's lithosphere—split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection.

I'm almost completely sure it's "A." If not, I'm so sorry.
