Explanation: Seafloor spreading helps explain continental drift in the theory of plate tectonics. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. ... At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed.
