The plate tectonics theory explains that earth's lithosphere (outer rigid shell) is composed of several dozen plates, or pieces, which float on a ductile mantle the theory describes how these plates may rift into pieces, diverging apart and forming a new ocean basin, followed by motion reversal, convergence back together, plate collision.
