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.
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
When mass is added to Earth's crust, it causes the crust to subside and sink due to the increased weight. Conversely, when mass is removed from the crust, it can rebound and rise due to the decreased load. This process is known as isostatic adjustment and can result in changes in the Earth's topography.
Oxygen is the most abundant element in the Earth's crust, making up about 46.6% of its mass.
The crust is about 40 kilometers thick in many places. The crust is the coldest layer of all the layers of earth. The crust makes up less than 1% of the earths mass. The crust is mainly made up of silicon,aluminum,calcium,sodium, and potassium.
The Mantle
The Earths crust.
No. The crust contains a small fraction of earth's mass. Most of the mass is contained in the mantle.
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 answer is athenosphere because it has less percent and since mantle has the most then athenosphere should have the 67% of the earths mass
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
About 2%
30%
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
