which statement best describes the theory of plate tectonics?\nplates sometimes move closer to one another.\nsections of earth that shift are part of earth’s asthenosphere.\nsections of earth’s continents are in slow, constant movement.\nparts of the ocean floor move as they are carried by rift valleys.

Answer

Brief Explanations:

The theory of plate tectonics states that the Earth's lithosphere is divided into tectonic plates that are in slow, constant motion. These plates can move closer to one another (convergent boundaries), move apart (divergent boundaries), or slide past each other (transform - boundaries). The sections in motion are part of the lithosphere, not the asthenosphere. Rift valleys are associated with divergent boundaries but the movement of ocean - floor is due to plate movement in general, not just being carried by rift valleys. The best description among the options is that sections of Earth's continents (which are part of the tectonic plates) are in slow, constant movement.

Answer:

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