The Earths crust.
If you're asking how much of the earth is in the crust layer, less than one percent. If you're asking what it's composition is:SiO2:60.6Al2O3:15.9CaO:6.4MgO:4.7Na2O:3.1Fe as FeO:6.7K2O:1.8TiO2:0.7P2O5:0.1
With a very sizable iron core and a (by comparison) wafer-thin crust, I doubt that the earth's crust even approximates a full percentage point.

No. The crust contains a small fraction of earth's mass. Most of the mass is contained in the mantle.
its the percentage in mass !
mass of Earth = 5.97219 × 1024 kilograms. Roughly.The mass of the earth is not represented by the earths crust
Silicates make up close to 95 percent of the rocks in the Earth's crust
the answer is athenosphere because it has less percent and since mantle has the most then athenosphere should have the 67% of the earths mass
30%
Oxygen comprises about 47% by weight of Earth's crust
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
