the process of seafloor spreading provide an explanation as to how the tectonic plates moved. True or False?

True.

Explanation:

Seafloor spreading helps explain continental drift in the theory of plate tectonics... Plates that are not subducting are driven by gravity sliding off the elevated mid-ocean ridges a process called ridge push. At a spreading center, basaltic magma rises up the fractures and cools on the ocean floor to form new seabed. Seafloor spreading occurs at divergent plate boundaries. As tectonic plates slowly move away from each other, heat from the mantle's convection currents makes the crust more plastic and less dense. The less-dense material rises, often forming a mountain or elevated area of the seafloor. Eventually, the crust cracks.

polar areas, such as antarctica or the south pole.
