The boundary between the Earth’s crust and the lithospheric mantle is known as the Mohorovičić discontinuity (short form: Moho; Fig. 1 ), named after the Croatian geophysicist Andrija S. Mohorovičić (1857–1936). Fig. 1 WebEarth’s outermost, rigid, rocky layer is called the crust. It is composed of low-density, easily melted rocks; the continental crust is predominantly granitic rock (see granite), while composition of the oceanic crust …
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earths structure.
