According to the theory of plate tectonics, the plates are: Choose one or more: A. discrete pieces of lithosphere which move with respect to one another. B. linked pieces of lithosphere which float atop the asthenosphere. C. composed of either continental or continental and oceanic lithosphere. D. moved by the creation of new crust and subduction of old crust. E. significantly more plastic than the rigid asthenosphere atop which they float.

The plate tectonic theory is one of the theories that leads to the concept of displacement of the earth's lithospheric crust.

Hence the option A, B, D, and E are correct.

Explanation:

Plate tectonics is the theory that Earth's outer shell is divided into several plates that glide over the mantle, the rocky inner layer above the core. The plates act like a hard and rigid shell compared to Earth's mantle.
