Which statement best describes the theory of plate tectonics?
•plates sometimes move closer to one another
•sections of earth that shift are parts of earths asthenosphere
•sections of earths continents are in slow constant movement
•parts of the ocean floor move as they are carried by rift valleys

The theory of plate tectonics describes sections of earth's continents are in slow constant movement.

Plate tectonics is the is present under the solid crust of the Earth that is known as lithosphere. These plates have the tendency to move in proportion constantly in order to form further new combinations.

Therefore, the theory is discussed as a scientific theory that demonstrates the formation of landforms due to the movements of Earth's subterranean.

The statement that best describes the theory of plate tectonics is the one that says that sections of Earth's continents are in slow constant movement.

Explanation:

Plate tectonics is a geological theory developed to explain the phenomenon of continental drift, that is, the continents of the earth are not invariably positioned on the surface of the earth but move in proportion to each other and constantly forming new combinations.

According to plate tectonic theory, the outermost part of the earth's interior consists of two layers, the outer lithosphere and the inner asthenosphere. Plate tectonics arose from two distinct geological observations: scattering zones and continental drift.
