WitrynaMovement of the liquid within the outer core generates Earth’s magnetic field. 2. The Mantle. It is the LARGEST layer of the earth that lies beneath the crust. It represents 84% of the Earth’s volume. This layer is composed of very hot, dense rock, and rich in the chemical elements. Oceanic crust is the uppermost layer of the oceanic portion of the tectonic plates. It is composed of the upper oceanic crust, with pillow lavas and a dike complex, and the lower oceanic crust, composed of troctolite, gabbro and ultramafic cumulates. The crust overlies the rigid uppermost layer of the mantle. The crust and the rigid upper mantle layer together constitute oceanic lithosphere.
