Final answer:

Continental and oceanic crust composition, asthenosphere, and mantle thickness.


Explanation:

The Composition of Earth's Crust and Mantle

Continental crust is primarily composed of granite rocks, while oceanic crust consists mainly of basaltic rocks. The Asthenosphere is known as the 'plastic mantle' due to its ability to flow slowly under stress. The mantle is the thickest layer of Earth, comprising mostly of iron and magnesium silicates and oxides.
