They are called tectonic or lithospheric plates.

Tectonic plates
The lithosphere is broken into about 100 separate sections called tectonic or crustal plates. They are divided by faults which are very much like cracks between plates. These plates float on top of the asthenosphere. A rift valley is a deep valley that forms where two plates move apart.
