The movement of the plates, and the activity inside the Earth, is described as the theory of plate tectonics.

Sinking in one place leads to plates moving apart in other places. The movement of the plates and the activity inside the Earth, is called the theory of plate tectonics.

This is because, although formulating the problem of electronic structure is trivial, solving it with reasonable computational resources is known to be exceptionally challenging. The problem is ...
