From the crust to the core, the density of the material increases. We shall discuss in detail the properties of each of this layer in the next chapter. Evolution of
Origin of the earth – Earth's crust – Composition. Origin of earth. Earth is one of the 9 planets (8 excluding Pluto) orbiting the SUN in the Solar. System.

Mg, Fe. – Dense (~2.9 g/cc). – impermanent. • Continental. – Thick (~35 km on average). – Heterogeneous. – “Granitic" - more properly. “granodioritic".
The origin and evolution of the Earth's continental crust. Stuart Ross Taylorl & Scott M. McLennan2. The present upper crustal composition of the Earth is attributed largely to intracrustal differentiation. resulting in the production of K-rich granites. The crust grows episodically and it is concluded that at least. 60 per cent of it

appropriate to discuss the origin тt the Earth and its composition as seen from a geochemical standpoint. A chapter on the rotation of the Earth is followed by aspects relating to the core through to the crust in sequence. The various chapters demonstrate the successful merging of geophysics and geochemistry that has been
Origin and Evolution of Earth. Research Questions for a Changing Planet. Questions about the origins and nature of Earth have long preoccupied human thought and the scientific endeavor. Deciphering the planet's history and processes could improve the abil- ity to predict catastrophes like earthquakes and volcanoes,
