"Sections of Earth's continents are in slow, constant movement."

Explanation: Plate tectonics says Earth's lithosphere is broken into plates (including continental plates) that move slowly over the asthenosphere. The other choices are incorrect or misleading (plates do converge sometimes, but that alone doesn't describe the theory; the moving sections are the rigid lithosphere, not the asthenosphere; ocean floor moves by seafloor spreading, not "carried by rift valleys").
