The Earths 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
The mantle makes up about 67% of Earth's mass.
The Mantle
the layer of rock that comprises 67% of earths mass
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.
The core!
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
The layer closest to the Earth's surface is the troposphere. It contains most of the atmosphere's mass and is where weather events occur.
The mantle is the layer of the Earth that makes up approximately 68% of the Earth's mass. It is located between the Earth's crust and core and consists of solid rock that can flow slowly over geological time scales.
The mantle and core make up the most percentage of Earth's mass. The mantle is the thickest layer and accounts for about 84% of Earth's total volume, while the core makes up about 32.5% of Earth's total mass.
earths mass = 5.974 * 10^24 kg, so 1 percent = 5.974 * 10^22 kg
