less than 1%
Silicates make up about 90% of Earth's crust. These minerals are composed of silicon and oxygen, along with other elements like aluminum, iron, calcium, and magnesium. Silicate minerals are the building blocks of most rocks on Earth's surface.
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.

Another word for Earth's outer surface is "crust."
About 2%.
mass of Earth = 5.97219 × 1024 kilograms. Roughly.The mass of the earth is not represented by the earths crust
The Earths crust.
Silicates make up close to 95 percent of the rocks in the Earth's crust
Oxygen comprises about 47% by weight of Earth's crust
The Earth's crust contains eight elements. The most common element among the eight is Oxygen (47 percent) and second is Silicon (28 percent).
The Earths crust is approximately 650 km deep.
Oxygen and silicon make up more than 80 percent of the atoms found in the Earth's crust. Oxygen is the most abundant element in the Earth's crust, comprising about 46.6% of the crust by weight, while silicon is the second most abundant at around 27.7%.
Quartz make up about 30 percent of earths continental crust...
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
