It plays a number of roles. First, the tectonic plates essentially float on the asthenosphere because they are less dense. Second, since oceanic crust is denser than continental crust, it can subduct into the mantle while continental crust cannot. Plate tectonics is driven in part by mantle convection, which results from variations in density due to temperature differences.
