Tectonics.
The branch of earth science that deals with the movements that shape the earth's crust is called tectonics. Tectonics studies the processes involved in the deformation, folding, faulting, and overall movement of the earth's lithosphere. It seeks to understand how and why the earth's crust changes over time.
Yes, that is true. The movement of the pieces of the Earth's crust is explained in a subject called plate tectonics.

Plate tectonics.
But plate tectonics is the theory which suggests that the Earth's crust is made up of solid plates moving relative to each other. Plate tectonics and the plate tectonics theory aren't really two separate things. However plates are pieces of the Earth's crust which are moving.
They are called plate tectonics.
