The mantle.
The Mantle takes up 84% of the Earth's mass.
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 Mantle
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.
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 layer of rock that comprises 67% of earths mass
The mantle.
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 Sun's photosphere comprises 0.77% oxygen by mass but is mostly hydrogen (73.5%).
