B. The Earth crust is divided into several large plates that move relative to each other.

Explanation:The Earth's crust is divided into Oceanic and continental plates,these plates move relative to each other. This movement leads to the formation of Midocean ridges and Mountains. The continental plate is less dense than the Oceanic plate. The continental plates are composed mainly of Sedimentary, Igneous and Metamorphic rocks while the Oceanic plate is made up of tectonic layers beneath the oceans.
