Thick mantle

WebWhile the continental crust is 30–70 km thick, the oceanic crustal thickness is 6–12 km. The oceanic crust is also denser (2.8–3.0 g/cm 3) than the continental crust (2.6–2.7 g/cm 3 ). The average Archean crust is ~35 km thick, whereas the Proterozoic crust is significantly thicker (~45 km). WebIt is 2900 km thick, and contains about 80% of the Earth’s volume. The mantle consists of iron and magnesium silicates and magnesium oxides, so it is more similar to the rocks of Earth’s surface than to the materials in the core. The mantle has a density of 4.5 g/cm 3, and temperatures in the range of 1000-1500 o C.
